Title = {Evidence of weaning stress in the long bones of a Central

Abstract = {Diaphyseal growth patterns are described and analysed for a
cross-sectional sample of immature Central California
Amerindian skeletal remains. This collection is housed at
the Lowie Museum of Anthropology, Berkeley, California, and
comprises the largest immature skeletal sample of
prehistoric Amerindians from the West Coast of North America
examined to date. Mean long bone length values and estimates
of growth velocity are compared to data reported for the
Indian Knoll and Arikara skeletal samples. The Central
California long bone growth curves are very similar to the
Indian Knoll and Arikara from birth through dental age 2. A
period of growth retardation is evident in the Central
California sample at dental age 3, both in comparison to the
Central California 2-year-olds and the Indian Knoll and
Arikara 3-year-olds. However, estimated growth velocity
indicates a comparable decline in growth rates for all three
groups between ages 2 and 3. Catch-up growth is exhibited in
the Central California long bones at dental ages 4 and 5.
The departure from the expected cross-sectional growth curve
between ages 3 and 5 is suggested to be correlated with the
onset of weaning and a subsequent slow-down in skeletal
growth. A method of quantitatively testing for the presence
of poor growth performance in archaeological skeletal
collections is applied to the Central California
data.},

Year = {1992},
Month = {June},
url = {http://dx.doi.org/10.1080/02724634.1992.10011448},
Abstract = {This study investigates the biomechanics of dental function
in Ptilodus (Multituberculata) through vector analysis of
masticatory muscles and comparisons of mechanically relevant
cranial and dental dimensions to extant functional
analogues. To isolate function, feeding behavior is divided
into incision, slicing-crushing, and grinding, and these
activities are related to corresponding dental regions
(incisors, premolars, and molars, respectively).
Quantitative comparisons to living mammals are made with
respect to inferred muscle vectors. The masticatory
apparatus of Ptilodus appears to have been adapted for a
variety of jaw movements, including powerful retraction
during the grinding cycle (utilizing the posterior part of
the temporalis muscle), and the generation of large bite
forces at a variety of tooth positions. The lateral
compression of p4 is one indication that resistant food
objects were a dietary component. However, the size and
orientation of the posterior surface of the mandibular
condyle indicates an upper size limit of approximately 10 mm
for relatively resistant items. The size and arrangement of
the bony and muscular structures indicate that the
masticatory apparatus was potentially versatile and, thus,
that Ptilodus and, by inference, other multituberculates,
were probably omnivorous. © 1992 by the Society of

Title = {EMG of the digastric muscle in gibbon and orangutan:
functional consequences of the loss of the anterior
digastric in orangutans.},
Journal = {American journal of physical anthropology},
Volume = {94},
Number = {4},
Pages = {549-567},
Year = {1994},
Month = {August},
ISSN = {0002-9483},
url = {http://dx.doi.org/10.1002/ajpa.1330940408},
Abstract = {Unlike all other primates, the digastric muscle of the
orangutan lacks an anterior belly; the posterior belly,
while present, inserts directly onto the mandible. To
understand the functional consequences of this morphologic
novelty, the EMG activity patterns of the digastric muscle
and other potential mandibular depressors were studied in a
gibbon and an orangutan. The results suggest a significant
degree of functional differentiation between the two
digastric bellies. In the gibbon, the recruitment pattern of
the posterior digastric during mastication is typically
biphasic. It is an important mandibular depressor, active in
this role during mastication and wide opening. It also acts
with the anterior suprahyoid muscles to move the hyoid prior
to jaw opening during mastication. The recruitment patterns
of the anterior digastric suggest that it is functionally
allied to the geniohyoid and mylohyoid. For example,
although it transmits the force of the posterior digastric
during mandibular depression, it functions independent of
the posterior digastric during swallowing. Of the muscles
studied, the posterior digastric was the only muscle to
exhibit major differences in recruitment pattern between the
two species. The posterior digastric retains its function as
a mandibular depressor in orangutans, but is never recruited
biphasically, and is not active prior to opening. The unique
anatomy of the digastric muscle in orangutans results in
decoupling of the mechanisms for hyoid movement and
mandibular depression, and during unilateral activity it
potentially contributes to substantial transverse movements
of the mandible. Hypotheses to explain the loss of the
anterior digastric should incorporate these functional
conclusions.},

Title = {Shape, relative size, and size‐adjustments in
morphometrics},
Journal = {American Journal of Physical Anthropology},
Volume = {38},

Pages = {137-161},
Publisher = {WILEY},

Abstract = {Many problems in comparative biology and biological
anthropology require meaningful definitions of “relative
size” and “shape.” Here we review the distinguishing
features of ratios and residuals and their relationships to
other methods of “size‐adjustment” for continuous
data. Eleven statistical techniques are evaluated in
reference to one broadly interspecific data set
(craniometries of adult Old World monkeys) and one narrowly
intraspecific data set (anthropometries of adult Native
American males). Three different types of residuals are
compared to three versions of shape ratios, and these are
contrasted to “cscores,” Penrose shape, and multivariate
adjustments based on the first principal component of the
logged variance‐covariance matrix; all methods are also
compared to raw and logged raw data. In order to help us
identify appropriate; methods for size‐adjustment,
geometrically similar or “isometric” versions of the
male vervet and the Inuit male were created by scalar
multiplication of all variables. The geometric mean of all
variables is used as overall “size” throughout this
investigation, but our conclusions would be the same for
most other size variables. Residual adjustments failed to
correctly identify individuals of the same shape in both
sampkles. Like residuals, cscores are also sample‐specific
and incorrectly attribute different shape values to
individuals known to be identical in shape. Multivariate
“residuals” (e.g., discarding the first principal
component and Burnaby's method) are plagued by similar
problems. If one of the goals of an analysis is to identify
individuals (OTUs) of the same shape after accounting for
overalll size differences, then none of these methods can be
recommended. We also reject the assertion that
size‐adjusted variables should be unciorrelated with size
of “size‐free”; rather, whether or not shape covaries
with size is an important empirical determination in any
analysis. Without explicit similarity criteria, “lines of
subtraction” can be very misleading. Only variables in the
Mosimann family of shape rations allowed us to identify
sized individuals of the same shape (“Iso‐OUTs”).
Residuals from isometric lines in logarithmic space,
projections of logged data to a plane orthogonal to an
isometric vector, and Penrose shape distance based on logged
data are also part of this shape family. Shape defined in
this manner can be significantly correlated with size in
allometric data sets (e.g., guenon craniometrics); ratio
shape differences may be largely independent of size in
narrowly intraspecific or intrasexual data sets (e.g.,
Native American anthropometrics). Log‐transformations of
shape variables are not always necessary or desirable. We
hope our findings enciourage other workers to question the
assumptions and utility of residuals as size‐adjusted data
and to explore shape and relative size within Mosimann's
explicitly geometric framework. © 1995 Wiley‐Liss, Inc.

Title = {The expanded mandibular condyle of the Megaladapidae.},
Journal = {American journal of physical anthropology},
Volume = {103},
Number = {2},
Pages = {263-276},
Year = {1997},
Month = {June},
ISSN = {0002-9483},

Abstract = {The Megaladapidae have a posterior expansion of the
articular surface of the mandibular condyle. Several other
strepsirhine species exhibit a similar condylar surface. In
this study, I propose two behavioral scenarios in which the
posterior articular expansion might function: 1) contact
with the postglenoid process and resistance to joint stress
during browsing, and 2) movement against the postglenoid
process during the fast closing and power strokes of
mastication, as a consequence of large transverse jaw
movements and associated with a strong mandibular symphysis.
These models are evaluated through dissection of the TMJ in
Lepilemur and from comparative anatomical observations on
strepsirhines and ungulates. In Lepilemur the mandibular
symphysis is unfused, but compared to the unfused symphyses
of other strepsirhines is strengthened by interlocking bony
projections (Beecher [1977] Am. J. Phys. Anthropol.
47:325-336). An accessory articular meniscus is found
between the posterior articular expansion and the
postglenoid process in Lepilemur, suggesting that
significant movement occurs in this part of the TMJ. The
symphysis is fused in adult specimens of Megaladapis. A
posterior articular expansion is common among ungulates, and
its presence is associated not with browsing but with
symphyseal fusion. This supports the second model and
suggests that the posterior articular expansion functions as
a movement surface during mastication. Schwartz and
Tattersall ([1987] J. Hum. Evol. 16:23-40) cite the
posterior articular expansion as a synapomorphy uniting an
Adapis-Leptadapis clade with a Megaladapidae-Daubentonia-Indridae
clade. The comparative evidence suggests that the posterior
articular expansion has evolved convergently in adapines,
notharctines, megaladapids, hapalemurids, and indrids as
part of a functional complex related to herbivory. However,
close morphological similarity of the posterior articular
expansion among genera within these strepsirhine subfamilies
and families indicates that it is probably a reliable
synapomorphy at lower taxonomic levels.},

Abstract = {The hypothesis that the shape of the bony temporomandibular
joint (TMJ) is functionally related to sagittal sliding of
the condyle during mastication is tested, and a model of the
relation of sagittal sliding to mandibular size, TMJ shape,
and diet is developed. Sagittal sliding is defined as
fore-aft motion of the condyle during mandibular translation
and/or angular rotation. Ascending ramus height is used as a
structural correlate of the distance between the condyle and
the mandibular axis of rotation (CR). Cineradiographic data
on sagittal sliding and gape during mastication in Ateles
spp., Macaca fascicularis, Papio anubis, and Pan troglodytes
in conjunction with comparative data on mandibular size and
TMJ shape are used to evaluate the hypothesis. The results
show that 1) linear and angular gape are highly positively
correlated with sagittal sliding, 2) pure mandibular
translation is rare during mastication, 3) the CR is rarely
if ever located at the condyle during mastication, 4)
angular gape should be standardized in interindividual
comparisons of sagittal sliding, and 5) the height of the
ascending ramus (and by inference the CR-to-condyle
distance) is highly positively correlated with absolute
sagittal sliding. Sagittal sliding relative to the length of
the articular eminence was the variable used to explore the
relation between TMJ shape and sliding. This variable
standardized absolute sagittal sliding relative to joint
size. The relative depth and orientation of the articular
eminence were not correlated with relative sagittal sliding.
The anteroposterior curvature of the condyle was highly
negatively correlated with relative sagittal sliding. Flat
condyles are associated with large amounts of relative
sagittal sliding. A flat condyle increases joint contact
area, which reduces joint stress. A flat condyle also
increases joint congruence, and this may facilitate the
combined sliding and rolling motion of the condyle when the
sliding motion is relatively large. The shape of the
entoglenoid process was also positively correlated with
relative sagittal sliding. A relatively large entoglenoid
process may help to guide sagittal sliding and prevent
excessive mediolateral sliding of the condyle. The
functional model makes a number of predictions about the
correlations between food consistency and food object size,
mandibular size, TMJ shape, and sagittal sliding of the
condyle during mastication and incision.},

Abstract = {The purpose of this study is to test various hypotheses
about balancing-side jaw muscle recruitment patterns during
mastication, with a major focus on testing the hypothesis
that symphyseal fusion in anthropoids is due mainly to
vertically- and/or transversely-directed jaw muscle forces.
Furthermore, as the balancing-side deep masseter has been
shown to play an important role in wishboning of the macaque
mandibular symphysis, we test the hypothesis that primates
possessing a highly mobile mandibular symphysis do not
exhibit the balancing-side deep masseter firing pattern that
causes wishboning of the anthropoid mandible. Finally, we
also test the hypothesis that balancing-side muscle
recruitment patterns are importantly related to allometric
constraints associated with the evolution of increasing body
size. Electromyographic (EMG) activity of the left and right
superficial and deep masseters were recorded and analyzed in
baboons, macaques, owl monkeys, and thick-tailed galagos.
The masseter was chosen for analysis because in the frontal
projection its superficial portion exerts force primarily in
the vertical (dorsoventral) direction, whereas its deep
portion has a relatively larger component of force in the
transverse direction. The symphyseal fusion-muscle
recruitment hypothesis predicts that unlike anthropoids,
galagos develop bite force with relatively little
contribution from their balancing-side jaw muscles. Thus,
compared to galagos, anthropoids recruit a larger percentage
of force from their balancing-side muscles. If true, this
means that during forceful mastication, galagos should have
working-side/balancing-side (W/B) EMG ratios that are
relatively large, whereas anthropoids should have W/B ratios
that are relatively small. The EMG data indicate that
galagos do indeed have the largest average W/B ratios for
both the superficial and deep masseters (2.2 and 4.4,
respectively). Among the anthropoids, the average W/B ratios
for the superficial and deep masseters are 1.9 and 1.0 for
baboons, 1.4 and 1.0 for macaques, and both values are 1.4
for owl monkeys. Of these ratios, however, the only
significant difference between thick-tailed galagos and
anthropoids are those associated with the deep masseter.
Furthermore, the analysis of masseter firing patterns
indicates that whereas baboons, macaques and owl monkeys
exhibit the deep masseter firing pattern associated with
wishboning of the macaque mandibular symphysis, galagos do
not exhibit this firing pattern. The allometric
constraint-muscle recruitment hypothesis predicts that
larger primates must recruit relatively larger amounts of
balancing-side muscle force so as to develop equivalent
amounts of bite force. Operationally this means that during
forceful mastication, the W/B EMG ratios for the superficial
and deep masseters should be negatively correlated with body
size. Our analysis clearly refutes this hypothesis. As
already noted, the average W/B ratios for both the
superficial and deep masseter are largest in thick-tailed
galagos, and not, as predicted by the allometric constraint
hypothesis, in owl monkeys, an anthropoid whose body size is
smaller than that of thick-tailed galagos. Our analysis also
indicates that owl monkeys have W/B ratios that are small
and more similar to those of the much larger-sized baboons
and macaques. Thus, both the analysis of the W/B EMG ratios
and the muscle firing pattern data support the hypothesis
that symphyseal fusion and transversely-directed muscle
force in anthropoids are functionally linked. This in turn
supports the hypothesis that the evolution of symphyseal
fusion in anthropoids is an adaptation to strengthen the
symphysis so as to counter increased wishboning stress
during forceful unilateral mastication. (ABSTRACT

gouge trees to elicit exudate flow whereas others scrape the
hardened gums from trees. These foraging behaviors are
thought to require high external forces at the anterior
dentition. In this study, we test whether skull form in
gouging and scraping galagids corresponds to this suggested
need to produce these higher external forces and to resist
increased internal loads in the jaws. We find few consistent
morphological patterns linking skull form and the generation
of high forces during gouging. However, there is some
tendency for gougers and scrapers to show increased load
resistance capabilities in their mandibles. Future research
on the mechanical properties of trees exploited by these
species and on jaw function during gouging and scraping will
improve our understanding of the mechanical demands of gum
feeding on the galagid skull form.},

Callithrix spp., Phaner furcifer, and most likely Euoticus
elegantulus elicit exudate flow by biting into trees with
their anterior dentition. We define this behavior as
gouging. Beyond the recent publication by Dumont ([1997] Am
J Phys Anthropol 102:187-202), there have been few attempts
to address whether any aspect of skull form in gouging
primates relates to this specialized feeding behavior.
However, many researchers have proposed that tree gouging
results in larger bite force, larger internal skull loads,
and larger jaw gapes in comparison to other chewing and
biting behaviors. If true, then we might expect primate
gougers to exhibit skull modifications that provide
increased abilities to produce bite forces at the incisors,
withstand loads in the skull, and/or generate large gapes
for gouging. We develop 13 morphological predictions based
on the expectation that gouging involves relatively large
jaw forces and/or jaw gapes. We compare skull shapes for P.
furcifer to five cheirogaleid taxa, E. elegantulus to six
galagid species, and C. jacchus to two tamarin species, so
as to assess whether gouging primates exhibit these
predicted morphological shapes. Our results show little
morphological evidence for increased force-production or
load-resistance abilities in the skulls of these gouging
primates. Conversely, these gougers tend to have skull
shapes that are advantageous for creating large gapes. For
example, all three gouging species have significantly lower
condylar heights relative to the toothrow at a given
mandibular length in comparison with closely related,
nongouging taxa. Lowering the height of the condyle relative
to the mandibular toothrow should reduce the stretching of
the masseters and medial pterygoids during jaw opening, as
well as position the mandibular incisors more anteriorly at
wide jaw gapes. In other words, the lower incisors will
follow a more vertical trajectory during both jaw opening
and closing. We predict, based on these findings, that
tree-gouging primates do not generate unusually large
forces, but that they do use relatively large gapes during
gouging. Of course, in vivo data on jaw forces and jaw gapes
are required to reliably assess skull functions during
gouging.},

Abstract = {We examined masseter and temporalis recruitment and firing
patterns during chewing in five male Belanger's treeshrews
(Tupaia belangeri), using electromyography (EMG). During
chewing, the working-side masseters tend to show almost
three times more scaled EMG activity than the balancing-side
masseters. Similarly, the working-side temporalis muscles
have more than twice the scaled EMG activity of the
balancing-side temporalis. The relatively higher activity in
the working-side muscles suggests that treeshrews recruit
less force from their balancing-side muscles during chewing.
Most of the jaw-closing muscles in treeshrews can be sorted
into an early-firing or late-firing group, based on
occurrence of peak activity during the chewing cycle.
Specifically, the first group of jaw-closing muscles to
reach peak activity consists of the working-side anterior
and posterior temporalis and the balancing-side superficial
masseter. The balancing-side anterior and posterior
temporalis and the working-side superficial masseter peak
later in the power stroke. The working-side deep masseter
peaks, on average, slightly before the working-side
superficial masseter. The balancing-side deep masseter
typically peaks early, at about the same time as the
balancing-side superficial masseter. Thus, treeshrews are
unlike nonhuman anthropoids that peak their working-side
deep masseters early and their balancing-side deep masseters
late in the power stroke. Because in anthropoids the late
firing of the balancing-side deep masseter contributes to
wishboning of the symphysis, the treeshrew EMG data suggest
that treeshrews do not routinely wishbone their symphyses
during chewing. Based on the treeshrew EMG data, we
speculate that during chewing, primitive euprimates 1)
recruited more force from the working-side jaw-closing
muscles as compared to the balancing-side muscles, 2) fired
an early group of jaw-closing muscles followed by a second
group of muscles that peaked later in the power stroke, 3)
did not fire their working-side deep masseter significantly
earlier than their working-side superficial masseter, and 4)
did not routinely fire their balancing-side deep masseter
after the working-side superficial masseter.},

Abstract = {The major purpose of this study is to analyze anterior and
posterior temporalis muscle force recruitment and firing
patterns in various anthropoid and strepsirrhine primates.
There are two specific goals for this project. First, we
test the hypothesis that in addition to transversely
directed muscle force, the evolution of symphyseal fusion in
primates may also be linked to vertically directed
balancing-side muscle force during chewing (Hylander et al.
[2000] Am. J. Phys. Anthropol. 112:469-492). Second, we test
the hypothesis of whether strepsirrhines retain the
hypothesized primitive mammalian condition for the firing of
the anterior temporalis, whereas anthropoids have the
derived condition (Weijs [1994] Biomechanics of Feeding in
Vertebrates; Berlin: Springer-Verlag, p. 282-320).
Electromyographic (EMG) activities of the left and right
anterior and posterior temporalis muscles were recorded and
analyzed in baboons, macaques, owl monkeys, thick-tailed
galagos, and ring-tailed lemurs. In addition, as we used the
working-side superficial masseter as a reference muscle, we
also recorded and analyzed EMG activity of the left and
right superficial masseter in these primates. The data for
the anterior temporalis provided no support for the
hypothesis that symphyseal fusion in primates is linked to
vertically directed jaw muscle forces during mastication.
Thus, symphyseal fusion in primates is most likely mainly
linked to the timing and recruitment of transversely
directed forces from the balancing-side deep masseter
(Hylander et al. [2000] Am. J. Phys. Anthropol.
112:469-492). In addition, our data demonstrate that the
firing patterns for the working- and balancing-side anterior
temporalis muscles are near identical in both strepsirrhines
and anthropoids. Their working- and balancing-side anterior
temporalis muscles fire asynchronously and reach peak
activity during the power stroke. Similarly, their working-
and balancing-side posterior temporalis muscles also fire
asynchronously and reach peak activity during the power
stroke. Compared to these strepsirrhines, however, the
balancing-side posterior temporalis of anthropoids appears
to have a relatively delayed firing pattern. Moreover, based
on their smaller W/B ratios, anthropoids demonstrate a
relative increase in muscle-force recruitment of the
balancing-side posterior temporalis. This in turn suggests
that anthropoids may emphasize the duration and magnitude of
the power stroke during mastication. This hypothesis,
however, requires additional testing. Furthermore, during
the latter portion of the power stroke, the late activity of
the balancing-side posterior temporalis of anthropoids
apparently assists the balancing-side deep masseter in
driving the working-side molars through the terminal portion
of occlusion.},

to be associated with shearing along a series of crests,

whether significant muscle activity and, by inference,

during phase II movement, there is negligible force
developed in the superficial and deep masseter and the

mandibular movements are small during phase II compared to
phase I. These results suggest that grinding during phase II
movement is of minimal importance for food breakdown, and
that most food breakdown on phase II facets occurs primarily
at the end of phase I movement (i.e., crushing during phase
I movement). We note, however, that depending on the

occurs along phase I facets during phase
I.},

Abstract = {We examined masseter recruitment and firing patterns during
chewing in four adult ring-tailed lemurs (Lemur catta),
using electromyography (EMG). During chewing of tougher
foods, the working-side superficial masseter tends to show,
on average, 1.7 times more scaled EMG activity than the
balancing-side superficial masseter. The working-side deep
masseter exhibits, on average, 2.4 times the scaled EMG
activity of the balancing-side deep masseter. The relatively
larger activity in the working-side muscles suggests that
ring-tailed lemurs recruit relatively less force from their
balancing-side muscles during chewing. The superficial
masseter working-to-balancing-side (W/B) ratio for lemurs
overlaps with W/B ratios from anthropoid primates. In
contrast, the lemur W/B ratio for the deep masseter is more
similar to that of greater galagos, while both are
significantly larger than W/B ratios of anthropoids. Because
ring-tailed lemurs have unfused and hence presumably weaker
symphyses, these data are consistent with the symphyseal
fusion-muscle recruitment hypothesis stating that symphyseal
fusion in anthropoids provides increased strength for
resisting forces created by the balancing-side jaw muscles
during chewing. Among the masseter muscles of ring-tailed
lemurs, the working-side deep masseter peaks first on
average, followed in succession by the balancing-side deep
masseter, balancing-side superficial masseter, and finally
the working-side superficial masseter. Ring-tailed lemurs
are similar to greater galagos in that their balancing-side
deep masseter peaks well before their working-side
superficial masseter. We see the opposite pattern in
anthropoids, where the balancing-side deep masseter peaks,
on average, after the working-side superficial masseter.
This late activity of the balancing-side deep masseter in
anthropoids is linked to lateral-transverse bending, or
wishboning, of their mandibular symphyses. Subsequently, the
stresses incurred during wishboning are hypothesized to be a
proximate reason for strengthening, and hence fusion, of the
anthropoid symphysis. Thus, the absence of this
muscle-firing pattern in ring-tailed lemurs with their
weaker, unfused symphyses provides further correlational
support for the symphyseal fusion late-acting balancing-side
deep masseter hypothesis linking wishboning and symphyseal
strengthening in anthropoids. The early peak activity of the
working-side deep masseter in ring-tailed lemurs is unlike
galagos and most similar to the pattern seen in macaques and
baboons. We hypothesize that this early activity of the
working-side deep masseter moves the lower jaw both
laterally toward the working side and vertically upward, to
position it for the upcoming power stroke. From an
evolutionary perspective, the differences in peak firing
times for the working-side deep masseter between ring-tailed
lemurs and greater galagos indicate that deep masseter
firing patterns are not conserved among strepsirrhines.},

Abstract = {We investigated patterns of jaw-muscle coordination during
rhythmic mastication in three species of ungulates
displaying the marked transverse jaw movements typical of
many large mammalian herbivores. In order to quantify
consistent motor patterns during chewing, electromyograms
were recorded from the superficial masseter, deep masseter,
posterior temporalis and medial pterygoid muscles of goats,
alpacas and horses. Timing differences between muscle pairs
were evaluated in the context of an evolutionary model of
jaw-muscle function. In this model, the closing and food
reduction phases of mastication are primarily controlled by
two distinct muscle groups, triplet I (balancing-side
superficial masseter and medial pterygoid and working-side
posterior temporalis) and triplet II (working-side
superficial masseter and medial pterygoid and balancing-side
posterior temporalis), and the asynchronous activity of the
working- and balancing-side deep masseters. The three
species differ in the extent to which the jaw muscles are
coordinated as triplet I and triplet II. Alpacas, and to a
lesser extent, goats, exhibit the triplet pattern whereas
horses do not. In contrast, all three species show marked
asynchrony of the working-side and balancing-side deep
masseters, with jaw closing initiated by the working-side
muscle and the balancing-side muscle firing much later
during closing. However, goats differ from alpacas and
horses in the timing of the balancing-side deep masseter
relative to the triplet II muscles. This study highlights
interspecific differences in the coordination of jaw muscles
to influence transverse jaw movements and the production of
bite force in herbivorous ungulates.},

Abstract = {Anthropologists studying primate chewing have focused on the
origins and evolution of the masticatory apparatus of
anthropoids and humans. We know far less about the
functional morphology and evolution of the masticatory
apparatus in the earliest euprimates (e.g., Jablonski,
1986). A more complete understanding of masticatory
apparatus function in the earliest primates would greatly
benefit studies of chewing behavior in both strepsirrhines
and haplorhines. We begin addressing this shortcoming in
this chapter by asking, "To what extent do treeshrews share
similar jaw-muscle activity patterns during chewing with
living primates?" We use the small, nonprimate mammal,
Belangers treeshrew (Tupaia belangeri), as an extant model
of jaw-muscle activity during chewing, or mastication, in
early euprimates. By comparing living primates to this
treeshrew, we can infer whether the origin of primates
involved significant changes in jaw-muscle activity patterns
during chewing. Because we can make some basic functional
links between jaw-muscle activity patterns and jaw form, our
results will aid future interpretations of masticatory
apparatus function from jaw form in living and fossil
primates. © Springer Science+Business Media, LLC

Abstract = {Biologists that study mammals continue to discuss the
evolution of and functional variation in jaw-muscle activity
during chewing. A major barrier to addressing these issues
is collecting sufficient in vivo data to adequately capture
neuromuscular variation in a clade. We combine data on
jaw-muscle electromyography (EMG) collected during
mastication from 14 species of primates and one of
treeshrews to assess patterns of neuromuscular variation in
primates. All data were collected and analyzed using the
same methods. We examine the variance components for EMG
parameters using a nested ANOVA design across successive
hierarchical factors from chewing cycle through species for
eight locations in the masseter and temporalis muscles.
Variation in jaw-muscle EMGs was not distributed equally
across hierarchical levels. The timing of peak EMG activity
showed the largest variance components among chewing cycles.
Relative levels of recruitment of jaw muscles showed the
largest variance components among chewing sequences and
cycles. We attribute variation among chewing cycles to (1)
changes in food properties throughout the chewing sequence,
(2) variation in bite location, and (3) the multiple ways
jaw muscles can produce submaximal bite forces. We
hypothesize that variation among chewing sequences is
primarily related to variation in properties of food. The
significant proportion of variation in EMGs potentially
linked to food properties suggests that experimental
biologists must pay close attention to foods given to
research subjects in laboratory-based studies of feeding.
The jaw muscles exhibit markedly different variance
components among species suggesting that primate jaw muscles
have evolved as distinct functional units. The
balancing-side deep masseter (BDM) exhibits the most
variation among species. This observation supports previous
hypotheses linking variation in the timing and activation of
the BDM to symphyseal fusion in anthropoid primates and in
strepsirrhines with robust symphyses. The working-side
anterior temporalis shows a contrasting pattern with little
variation in timing and relative activation across primates.
The consistent recruitment of this muscle suggests that
primates have maintained their ability to produce vertical
jaw movements and force in contrast to the evolutionary
changes in transverse occlusal forces driven by the varying
patterns of activation in the BDM.},

Abstract = {The goal of this study is to clarify the functional and
biomechanical relationship between jaw morphology and in
vivo masticatory loading in selenodont artiodactyls. We
compare in vivo strains from the mandibular corpus of goats
and alpacas to predicted strain patterns derived from
biomechanical models for mandibular corpus loading during
mastication. Peak shear strains in both species average
600-700 microepsilon on the working side and approximately
450 microepsilon on the balancing side. Maximum principal
tension in goats and alpacas is directed at approximately 30
degrees dorsocaudally relative to the long axis of the
corpus on the working side and approximately perpendicular
to the long axis on the balancing side. Strain patterns in
both species indicate primarily torsion of the working-side
corpus about the long axis and parasagittal bending and/or
lateral transverse bending of the balancing-side corpus.
Interpretation of the strain patterns is consistent with
comparative biomechanical analyses of jaw morphology
suggesting that in goats, the balancing-side mandibular
corpus is parasagittally bent whereas in alpacas it
experiences lateral transverse bending. However, in light of
higher working-side corpus strains, biomechanical
explanations of mandibular form also need to consider that
torsion influences relative corpus size and shape.
Furthermore, the complex combination of loads that occur
along the selenodont artiodactyl mandibular corpus during
the power stroke has two implications. First, added
clarification of these loading patterns requires in vivo
approaches for elucidating biomechanical links between
mandibular corpus morphology and masticatory loading.
Second, morphometric approaches may be limited in their
ability to accurately infer masticatory loading regimes of
selenodont artiodactyl jaws.},

Abstract = {The social brain hypothesis proposes that haplorhine
primates have evolved relatively large brains for their body
size primarily as an adaptation for living in complex social
groups. Studies that support this hypothesis have shown a
strong relationship between relative brain size and group
size in these taxa. Recent reports suggest that this pattern
is unique to haplorhine primates; many nonprimate taxa do
not show a relationship between group size and relative
brain size. Rather, pairbonded social monogamy appears to be
a better predictor of a large relative brain size in many
nonprimate taxa. It has been suggested that haplorhine
primates may have expanded the pairbonded relationship
beyond simple dyads towards the evolution of complex social
groups. We examined the relationship between group size,
pairbonding, and relative brain size in a sample of 19
lemurs; strepsirrhine primates that last share a common
ancestor with monkeys and apes approximately 75 Ma. First,
we evaluated the social brain hypothesis, which predicts
that species with larger social groups will have relatively
larger brains. Secondly, we tested the pairbonded
hypothesis, which predicts that species with a pairbonded
social organization will have relatively larger brains than
non-pairbonded species. We found no relationship between
group size or pairbonding and relative brain size in lemurs.
We conducted two further analyses to test for possible
relationships between two nonsocial variables, activity
pattern and diet, and relative brain size. Both diet and
activity pattern are significantly associated with relative
brain size in our sample. Specifically, frugivorous species
have relatively larger brains than folivorous species, and
cathemeral species have relatively larger brains than
diurnal, but not nocturnal species. These findings highlight
meaningful differences between Malagasy strepsirrhines and
haplorhines, and between Malagasy strepsirrhines and
nonprimate taxa, regarding the social and ecological factors
associated with increases in relative brain size. The
results suggest that factors such as foraging complexity and

Abstract = {Differences in cognitive abilities and the relatively large
brain are among the most striking differences between humans
and their closest primate relatives. The energy trade-off
hypothesis predicts that a major shift in energy allocation
among tissues occurred during human origins in order to
support the remarkable expansion of a metabolically
expensive brain. However, the molecular basis of this
adaptive scenario is unknown. Two glucose transporters
(SLC2A1 and SLC2A4) are promising candidates and present
intriguing mutations in humans, resulting, respectively, in
microcephaly and disruptions in whole-body glucose
homeostasis. We compared SLC2A1 and SLC2A4 expression
between humans, chimpanzees and macaques, and found
compensatory and biologically significant expression changes
on the human lineage within cerebral cortex and skeletal
muscle, consistent with mediating an energy trade-off. We
also show that these two genes are likely to have undergone
adaptation and participated in the development and
maintenance of a larger brain in the human lineage by
modulating brain and skeletal muscle energy allocation. We
found that these two genes show human-specific signatures of
positive selection on known regulatory elements within their
5'-untranslated region, suggesting an adaptation of their
regulation during human origins. This study represents the
first case where adaptive, functional and genetic lines of
evidence implicate specific genes in the evolution of human
brain size.},

Abstract = {Body size and food properties account for much of the
variation in the hard tissue morphology of the masticatory
system whereas their influence on the soft tissue anatomy
remains relatively understudied. Data on jaw adductor fiber
architecture and experimentally determined ingested food
size in a broad sample of 24 species of extant
strepsirrhines allows us to evaluate several hypotheses
about the influence of body size and diet on the masticatory
muscles. Jaw adductor mass scales isometrically with body
mass (β = 0.99, r = 0.95), skull size (β = 1.04, r =
0.97), and jaw length cubed (β = 1.02, r = 0.95). Fiber
length also scales isometrically with body mass (β = 0.28,
r = 0.85), skull size (β = 0.33, r = 0.84), and jaw length
cubed (β = 0.29, r = 0.88). Physiological cross-sectional
area (PCSA) scales with isometry or slight positive
allometry with body mass (β = 0.76, r = 0.92), skull size
(β = 0.78, r = 0.94), and jaw length cubed (β = 0.78, r =
0.91). Whereas PCSA is isometric to body size estimates in
frugivores, it is positively allometric in folivores.
Independent of body size, fiber length is correlated with
maximum ingested food size, suggesting that ingestive gape
is related to fiber excursion. Comparisons of temporalis,
masseter, and medial pterygoid PCSA in strepsirrhines of
different diets suggest that there may be functional
partitioning between these muscle groups.},

Abstract = {The establishment of a publicly-accessible repository of
physiological data on feeding in mammals, the Feeding
Experiments End-user Database (FEED), along with
improvements in reconstruction of mammalian phylogeny,
significantly improves our ability to address long-standing
questions about the evolution of mammalian feeding. In this
study, we use comparative phylogenetic methods to examine
correlations between jaw robusticity and both the relative
recruitment and the relative time of peak activity for the
superficial masseter, deep masseter, and temporalis muscles
across 19 mammalian species from six orders. We find little
evidence for a relationship between jaw robusticity and
electromyographic (EMG) activity for either the superficial
masseter or temporalis muscles across mammals. We
hypothesize that future analyses may identify significant
associations between these physiological and morphological
variables within subgroups of mammals that share similar
diets, feeding behaviors, and/or phylogenetic histories.
Alternatively, the relative peak recruitment and timing of
the balancing-side (i.e., non-chewing-side) deep masseter
muscle (BDM) is significantly negatively correlated with the
relative area of the mandibular symphysis across our
mammalian sample. This relationship exists despite BDM
activity being associated with different loading regimes in
the symphyses of primates compared to ungulates, suggesting
a basic association between magnitude of symphyseal loads
and symphyseal area among these mammals. Because our sample
primarily represents mammals that use significant transverse
movements during chewing, future research should address
whether the correlations between BDM activity and symphyseal
morphology characterize all mammals or should be restricted
to this "transverse chewing" group. Finally, the significant
correlations observed in this study suggest that
physiological parameters are an integrated and evolving
component of feeding across mammals.},

Abstract = {Descriptive and quantitative analyses of electromyograms
(EMG) from the jaw adductors during feeding in mammals have
demonstrated both similarities and differences among species
in chewing motor patterns. These observations have led to a
number of hypotheses of the evolution of motor patterns, the
most comprehensive of which was proposed by Weijs in 1994.
Since then, new data have been collected and additional
hypotheses for the evolution of motor patterns have been
proposed. Here, we take advantage of these new data and a
well-resolved species-level phylogeny for mammals to test
for the correlated evolution of specific components of
mammalian chewing motor patterns. We focus on the evolution
of the coordination of working-side (WS) and balancing-side
(BS) jaw adductors (i.e., Weijs' Triplets I and II), the
evolution of WS and BS muscle recruitment levels, and the
evolution of asynchrony between pairs of muscles. We
converted existing chewing EMG data into binary traits to
incorporate as much data as possible and facilitate robust
phylogenetic analyses. We then tested hypotheses of
correlated evolution of these traits across our phylogeny
using a maximum likelihood method and the Bayesian Markov
Chain Monte Carlo method. Both sets of analyses yielded
similar results highlighting the evolutionary changes that
have occurred across mammals in chewing motor patterns. We
find support for the correlated evolution of (1) Triplets I
and II, (2) BS deep masseter asynchrony and Triplets I and
II, (3) a relative delay in the activity of the BS deep
masseter and a decrease in the ratio of WS to BS muscle
recruitment levels, and (4) a relative delay in the activity
of the BS deep masseter and a delay in the activity of the
BS posterior temporalis. In contrast, changes in relative WS
and BS activity levels across mammals are not correlated
with Triplets I and II. Results from this work can be
integrated with dietary and morphological data to better
understand how feeding and the masticatory apparatus have
evolved across mammals in the context of new masticatory
demands.},

Abstract = {Jaw-muscle electromyographic (EMG) patterns indicate that
compared with thick-tailed galagos and ring-tailed lemurs,
anthropoids recruit more relative EMG from their
balancing-side deep masseter, and that this muscle peaks
late in the power stroke. These recruitment and firing
patterns in anthropoids are thought to cause the mandibular
symphysis to wishbone (lateral transverse bending),
resulting in relatively high symphyseal stresses. We test
the hypothesis that living strepsirrhines with robust,
partially fused symphyses have muscle recruitment and firing
patterns more similar to anthropoids, unlike those
strepsirrhines with highly mobile unfused symphyses.
Electromyographic (EMG) activity of the superficial and deep
masseter, anterior and posterior temporalis, and medial
pterygoid muscles were recorded in four dentally adult
Verreaux's sifakas (Propithecus verreauxi). As predicted, we
find that sifaka motor patterns are more similar to
anthropoids. For example, among sifakas, recruitment levels
of the balancing-side (b-s) deep masseter are high, and the
b-s deep masseter fires late during the power stroke. As
adult sifakas often exhibit nearly complete symphyseal
fusion, these data support the hypothesis that the evolution
of symphyseal fusion in primates is functionally linked to
wishboning. Furthermore, these data provide compelling
evidence for the convergent evolution of the wishboning
motor patterns in anthropoids and sifakas.},

Abstract = {Previous research has revealed significant size differences
between human male and female carpal bones but it is unknown
if there are significant shape differences as well. This
study investigated sex-related shape variation and
allometric patterns in five carpal bones that make up the
radiocarpal and midcarpal joints in modern humans. We found
that many aspects of carpal shape (76% of all variables
quantified) were similar between males and females, despite
variation in size. However, 10 of the shape ratios were
significantly different between males and females, with at
least one significant shape difference observed in each
carpal bone. Within-sex standard major axis regressions
(SMA) of the numerator (i.e., the linear variables) on the
denominator (i.e., the geometric mean) for each
significantly different shape ratio indicated that most
linear variables scaled with positive allometry in both
males and females, and that for eight of the shape ratios,
sex-related shape variation is associated with statistically
similar sex-specific scaling relationships. Only the length
of the scaphoid body and the height of the lunate triquetrum
facet showed a significantly higher SMA slope in females
compared with males. These findings indicate that the
significant differences in the majority of the shape ratios
are a function of subtle (i.e., not statistically
significant) scaling differences between males and females.
There are a number of potential developmental, functional,
and evolutionary factors that may cause sex-related shape
differences in the human carpus. The results highlight the
potential for subtle differences in scaling to result in
functionally significant differences in shape.},

Abstract = {<h4>Objective</h4>The purpose of this study was to determine
whether high amounts of fast/type II myosin heavy chain
(MyHC) in the superficial as compared to the deep temporalis
muscle of adult female and male baboons (Papio anubis)
correlates with published data on muscle function during
chewing. Electromyographic (EMG) data show a regional
specialization in activation from low to high amplitude
activity during hard/tough object chewing cycles in the
baboon superficial temporalis.(48,49) A positive correlation
between fast/type II MyHC amount and EMG activity will
support the high occlusal force hypothesis.<h4>Design</h4>Deep
anterior temporalis (DAT), superficial anterior temporalis
(SAT), and superficial posterior temporalis (SPT) muscle
samples were analyzed using SDS-PAGE gel electrophoresis to
test the prediction that SAT and SPT will show high amounts
of fast/type II MyHC compared to DAT. Serial muscle sections
were incubated against NOQ7.5.4D and MY32 antibodies to
determine the breadth of slow/type I versus fast/type II
expression within each section.<h4>Results</h4>Type I and
type IIM MyHCs comprise nearly 100% of the MyHCs in the
temporalis muscle. IIM MyHC was the overwhelmingly
predominant fast MyHC, though there was a small amount of
type IIA MyHC (≤5%) in DAT in two individuals. SAT and SPT
exhibited a fast/type II phenotype and contained large
amounts of IIM MyHC whereas DAT exhibited a type I/type II
(hybrid) phenotype and contained a significantly greater
proportion of MyHC-I. MyHC-I expression in DAT was sexually
dimorphic as it was more abundant in females.<h4>Conclusions</h4>The
link between the distribution of IIM MyHC and high relative
EMG amplitudes in SAT and SPT during hard/tough object
chewing cycles is evidence of regional specialization in
fibre type to generate high occlusal forces during chewing.
The high proportion of MyHC-I in DAT of females may be
related to a high frequency of individual fibre recruitment
in comparison to males.},

Abstract = {Enamel thickness varies substantially among extant hominoids
and is a key trait with significance for interpreting
dietary adaptation, life history trajectory, and
phylogenetic relationships. There is a strong link in humans
between enamel formation and mutations in the exons of the
four genes that code for the enamel matrix proteins and the
associated protease. The evolution of thick enamel in humans
may have included changes in the regulation of these genes
during tooth development. The cis-regulatory region in the
5' flank (upstream non-coding region) of MMP20, which codes
for enamelysin, the predominant protease active during
enamel secretion, has previously been shown to be under
strong positive selection in the lineages leading to both
humans and chimpanzees. Here we examine evidence for
positive selection in the 5' flank and 3' flank of AMELX,
AMBN, ENAM, and MMP20. We contrast the human sequence
changes with other hominoids (chimpanzees, gorillas,
orangutans, gibbons) and rhesus macaques (outgroup), a
sample comprising a range of enamel thickness. We find no
evidence for positive selection in the protein-coding
regions of any of these genes. In contrast, we find strong
evidence for positive selection in the 5' flank region of
MMP20 and ENAM along the lineage leading to humans, and in
both the 5' flank and 3' flank regions of MMP20 along the
lineage leading to chimpanzees. We also identify putative
transcription factor binding sites overlapping some of the
species-specific nucleotide sites and we refine which
sections of the up- and downstream putative regulatory
regions are most likely to harbor important changes. These
non-coding changes and their potential for differential
regulation by transcription factors known to regulate tooth
development may offer insight into the mechanisms that allow
for rapid evolutionary changes in enamel thickness across
closely-related species, and contribute to our understanding
of the enamel phenotype in hominoids.},

Abstract = {Galago senegalensis is a habitual arboreal leaper that
engages in rapid spinal extension during push-off. Large
muscle excursions and high contraction velocities are
important components of leaping, and experimental studies
indicate that during leaping by G. senegalensis, peak power
is facilitated by elastic storage of energy. To date,
however, little is known about the functional relationship
between epaxial muscle fiber architecture and locomotion in
leaping primates. Here, fiber architecture of select epaxial
muscles is compared between G. senegalensis (n = 4) and the
slow arboreal quadruped, Nycticebus coucang (n = 4). The
hypothesis is tested that G. senegalensis exhibits
architectural features of the epaxial muscles that
facilitate rapid and powerful spinal extension during the
take-off phase of leaping. As predicted, G. senegalensis
epaxial muscles have relatively longer, less pinnate fibers
and higher ratios of tendon length-to-fiber length,
indicating the capacity for generating relatively larger
muscle excursions, higher whole-muscle contraction
velocities, and a greater capacity for elastic energy
storage. Thus, the relatively longer fibers and higher
tendon length-to-fiber length ratios can be functionally
linked to leaping performance in G. senegalensis. It is
further predicted that G. senegalensis epaxial muscles have
relatively smaller physiological cross-sectional areas
(PCSAs) as a consequence of an architectural trade-off
between fiber length (excursion) and PCSA (force). Contrary
to this prediction, there are no species differences in
relative PCSAs, but the smaller-bodied G. senegalensis
trends towards relatively larger epaxial muscle mass. These
findings suggest that relative increase in muscle mass in G.
senegalensis is largely attributable to longer fibers. The
relative increase in erector spinae muscle mass may
facilitate sagittal flexibility during leaping. The
similarity between species in relative PCSAs provides
empirical support for previous work linking osteological
features of the vertebral column in lorisids with axial
stability and reduced muscular effort associated with slow,
deliberate movements during anti-pronograde
locomotion.},

Abstract = {<h4>Background</h4>In recent years large bibliographic
databases have made much of the published literature of
biology available for searches. However, the capabilities of
the search engines integrated into these databases for
text-based bibliographic searches are limited. To enable
searches that deliver the results expected by comparative
anatomists, an underlying logical structure known as an
ontology is required.<h4>Development and testing of the
ontology</h4>Here we present the Mammalian Feeding Muscle
Ontology (MFMO), a multi-species ontology focused on
anatomical structures that participate in feeding and other
oral/pharyngeal behaviors. A unique feature of the MFMO is
that a simple, computable, definition of each muscle, which
includes its attachments and innervation, is true across
mammals. This construction mirrors the logical foundation of
comparative anatomy and permits searches using language
familiar to biologists. Further, it provides a template for
muscles that will be useful in extending any anatomy
ontology. The MFMO is developed to support the Feeding
Experiments End-User Database Project (FEED,
https://feedexp.org/), a publicly-available, online
repository for physiological data collected from in vivo
studies of feeding (e.g., mastication, biting, swallowing)
in mammals. Currently the MFMO is integrated into FEED and
also into two literature-specific implementations of
Textpresso, a text-mining system that facilitates powerful
searches of a corpus of scientific publications. We evaluate
the MFMO by asking questions that test the ability of the
ontology to return appropriate answers (competency
questions). We compare the results of queries of the MFMO to
results from similar searches in PubMed and Google
Scholar.<h4>Results and significance</h4>Our tests
demonstrate that the MFMO is competent to answer queries
formed in the common language of comparative anatomy, but
PubMed and Google Scholar are not. Overall, our results show
that by incorporating anatomical ontologies into searches,
an expanded and anatomically comprehensive set of results
can be obtained. The broader scientific and publishing
communities should consider taking up the challenge of
semantically enabled search capabilities.},

Abstract = {A major goal of evolutionary studies is to better understand
how complex morphologies are related to the different
functions and behaviours in which they are involved. For
example, during locomotion and hunting behaviour, the head
and the eyes have to stay at an appropriate level in order
to reliably judge distance as well as to provide postural
information. The morphology and orientation of the orbits
and cranial base will have an impact on eye orientation.
Consequently, variation in orbital and cranial base
morphology is expected to be correlated with aspects of an
animal's lifestyle. In this study, we investigate whether
the shape of the skull evolves in response to the functional
demands imposed by ecology and behaviour using geometric
morphometric methods. We test if locomotor habitats, diet,
and activity pattern influence the shape of the skull in
musteloid carnivorans using (M)ANOVAs and phylogenetic
(M)ANOVAs, and explore the functional correlates of
morphological features in relation to locomotor habitats,
diet, and activity pattern. Our results show that phylogeny,
locomotion and, diet strongly influence the shape of the
skull, whereas the activity pattern seems to have a weakest
influence. We also show that the locomotor environment is
highly integrated with foraging and feeding, which can lead
to similar selective pressures and drive the evolution of
skull shape in the same direction. Finally, we show similar
responses to functional demands in musteloids, a super
family of close related species, as are typically observed
across all mammals suggesting the pervasiveness of these
functional demands.},

Abstract = {The origin and evolution of manual grasping remain poorly
understood. The ability to cling requires important grasping
abilities and is essential to survive in species where the
young are carried in the fur. A previous study has suggested
that this behaviour could be a pre-adaptation for the
evolution of fine manipulative skills. In this study we
tested the co-evolution between infant carrying in the fur
and manual grasping abilities in the context of food
manipulation. As strepsirrhines vary in the way infants are
carried (mouth vs. fur), they are an excellent model to test
this hypothesis. Data on food manipulation behaviour were
collected for 21 species of strepsirrhines. Our results show
that fur-carrying species exhibited significantly more
frequent manual grasping of food items. This study clearly
illustrates the potential novel insights that a behaviour
(infant carrying) that has previously been largely ignored
in the discussion of the evolution of primate manipulation
can bring.},

Abstract = {Analyses of muscular activity during rhythmic behaviors
provide critical data for biomechanical studies. Electrical
potentials measured from muscles using electromyography
(EMG) require discrimination of noise regions as the first
step in analysis. An experienced analyst can accurately
identify the onset and offset of EMG but this process takes
hours to analyze a short (10-15s) record of rhythmic EMG
bursts. Existing computational techniques reduce this time
but have limitations. These include a universal threshold
for delimiting noise regions (i.e., a single signal value
for identifying the EMG signal onset and offset),
pre-processing using wide time intervals that dampen
sensitivity for EMG signal characteristics, poor performance
when a low frequency component (e.g., DC offset) is present,
and high computational complexity leading to lack of time
efficiency. We present a new statistical method and MATLAB
script (EMG-Extractor) that includes an adaptive algorithm
to discriminate noise regions from EMG that avoids these
limitations and allows for multi-channel datasets to be
processed. We evaluate the EMG-Extractor with EMG data on
mammalian jaw-adductor muscles during mastication, a
rhythmic behavior typified by low amplitude onsets/offsets
and complex signal pattern. The EMG-Extractor consistently
and accurately distinguishes noise from EMG in a manner
similar to that of an experienced analyst. It outputs the
raw EMG signal region in a form ready for further
analysis.},

Abstract = {OBJECTIVE: The jaw-closing muscles of humans and nonprimate
mammals express alpha-cardiac fibers but MyHC α-cardiac has
not been identified in the jaw adductors of nonhuman
primates. We determined whether MyHC α-cardiac is expressed
in the superficial masseter and temporalis muscles of the
sooty mangabey (Cercocebus atys), an African Old World
monkey that specializes on hard seeds. DESIGN: LC-MS/MS
based proteomics was used to identify the presence of MyHC
Iα. Immunohistochemistry was used to analyze the
composition and distribution of fiber types in the
superficial masseter and temporalis muscles of eight C.
atys. Serial sections were stained against MyHC α-cardiac
(MYH6), as well as MyHC-1 (NOQ7.5.4D), MyHC-2 (MY-32), and
MyHC-M (2F4). RESULTS: Proteomics analysis identified the
presence of Myosin-6 (MyHC α-cardiac) in both heart atrium
and superficial masseter. MyHC α-cardiac was expressed in
abundance in the superficial masseter and temporalis muscles
of all eight individuals and hybrid fibers were common.
CONCLUSIONS: The identification of MyHC α-cardiac in the
jaw adductors of sooty mangabeys is a novel finding for
nonhuman primates. The abundance of MyHC α-cardiac
indicates a fatigue-resistant fiber population characterized
by intermediate speed of contraction between pure MyHC-1 and
MyHC-2 isoforms. We suggest that α-cardiac fibers may be
advantageous to sooty mangabeys, whose feeding behavior
includes frequent crushing of relatively large, hard seeds
during the power stroke of ingestion. Additional studies
comparing jaw-adductor fiber phenotype of hard-object
feeding primates and other mammals are needed to explore
this relationship further.},

Abstract = {Speed-related gait transitions occur in many animals, but it
remains unclear what factors trigger gait changes. While the
most widely accepted function of gait transitions is that
they reduce locomotor costs, there is no obvious metabolic
trigger signalling animals when to switch gaits. An
alternative approach suggests that gait transitions serve to
reduce locomotor instability. While there is evidence
supporting this in humans, similar research has not been
conducted in other species. This study explores energetics
and stride variability during the walk-run transition in
mammals and birds. Across nine species, energy savings do
not predict the occurrence of a gait transition. Instead,
our findings suggest that animals trigger gait transitions
to maintain high locomotor rhythmicity and reduce unstable
states. Metabolic efficiency is an important benefit of gait
transitions, but the reduction in dynamic instability may be
the proximate trigger determining when those transitions
occur.},

Abstract = {Although hand grasping is ubiquitous in primate species, its
origins remain uncertain. This is in part because
uncertainty about hand skills and grasping strategies
persists in strepsirrhines, a monophyletic group of primates
located near the base of the primate tree. In this study, we
report and discuss our observations of the different
grasping strategies adopted by 85 captive individuals
belonging to 22 species of strepsirrhines during the
grasping of food items of different sizes and consistencies.
Our results indicate that although strepsirrhines do not
present variability in their hand-grip types (sole
whole-hand power grip), they are able to adjust their
grasping strategy depending on the properties of the food.
Notably, they use the mouth when more precision is needed
(i.e. to grasp small items). Moreover, grasping strategies
adopted for big items differ depending on food consistency,
revealing a new and potentially essential factor to consider
in future research on grasping abilities. We believe that by
looking across this important set of species in
unconstrained standardized conditions, this study provides
valuable insight for further comparative research on the
potential selective pressures involved in the evolution of
hand grasping.},

Abstract = {Fine prehensile activities are often thought to have been
associated with the evolution of the human hand. However,
there has been no holistic approach establishing the link
between the morphology of the forelimb and grasping ability

possible relationships between grasping behaviour and the
morphology of the forelimb in strepsirrhines in a
phylogenetic context. To do so, grasping behaviour during
feeding and the shape of the long bones of the forelimb were
analysed for 22 species of strepsirrhines. The data obtained
show that there is a phylogenetic signal in forelimb
morphology in primates in relation to grasping behaviour,
but also that there is a marked co-evolution between
grasping behaviour and the shape of the humerus and radius.
This latter finding suggests a functional association
between grasping and forelimb shape, which in turn suggests
that bone shape constrains or facilitates behaviour. This
result may permit future inferences to be made regarding
this behaviour in extinct species and deserves further

Abstract = {Manual grasping is widespread among tetrapods but is more
prominent and dexterous in primates. Whether the selective
pressures that drove the evolution of dexterous hand
grasping involved the collection of fruit or predation on
mobile insects remains an area of debate. One way to explore
this question is to examine preferences for manual versus
oral grasping of a moving object. Previous studies on
strepsirrhines have shown a preference for oral grasping
when grasping static food items and a preference for manual
grasping when grasping mobile prey such as insects, but
little is known about the factors at play. Using a
controlled experiment with a simple and predictable motion
of a food item, we tested and compared the grasping
behaviours of 53 captive individuals belonging to 17 species
of strepsirrhines while grasping swinging food items and
static food items. The swinging motion increased the
frequency of hand-use for all individuals. Our results
provide evidence that the swinging motion of the food is a
sufficient parameter to increase hand grasping in a wide
variety of strepsirrhine primates. From an evolutionary
perspective, this result gives some support to the idea that
hand-grasping abilities evolved under selective pressure
associated with the predation of food items in motion.
Looking at a common grasping pattern across a large set of
species, this study provides important insight into
comparative approaches to understanding the evolution of the
hand grasping of food in primates and potentially other
tetrapod taxa.},

improvisational adjustments (online control), or some
combination of both. In this study, the gaze profiles of 5
male and 5 female runners, fitted with a telemetric

fixations on an obstacle during a run. Overall, participants
fixated on the obstacle 2.4 times during the run, with the
last fixation occurring on average between 40% and 80% of
the run, suggesting runners potentially shifted from a
feedforward planning strategy to an online control strategy
during the late portions of the running trial. A negative
association was observed between runner velocity and average
number of fixations. Consistent with previous studies on
visual strategies used during walking, our results indicate
that visual attentiveness is part of an important
feedforward strategy for runners allowing them to safely
approach an obstacle. Thus, visual obstacle attention is a
key factor in the navigation of complex, natural landscapes

we review relevant literature and online sources, and

While doing so this animal inserts the entire length of its
extra-long, skinny and highly mobile middle finger into the
nasal passages and then licks the nasal mucus collected. We
further investigate the internal anatomy of the nasal cavity
of the aye-aye in order to understand how it can introduce
its entire finger in its nasal cavity and discover that the
finger likely descends into the pharynx. We show that this
behaviour is present in at least 12 species of primates,

Abstract = {Anthropoid vision contributes not only to reaching and
grasping but also to the orienting of a food item during the
withdraw movement to precisely place it in the mouth for
eating. The evolutionary history of this visual control of
feeding is not known. It likely evolved from the nonvisual
control of the hand that is used with good effect for eating
in many non-primate animal species. Strepsirrhines are a
relatively large monophyletic group, diverging near the base
of the primate cladogram, and described as using vision to
reach for food. It is not known whether they use vision to
orient food items during the withdraw movement. Video
recordings of 7,464 withdraw movements from 22 species of
captive strepsirrhines eating their normal food provisions
were used to assess whether and how vision contributes to
the withdraw movement. The constituent acts of withdraw
movements, head orientation, body posture, ground-withdraw
and inhand-withdraw, were assessed using frame-by-frame
video inspection. Strepsirrhines were versatile in using
their hands to get food to the mouth. They displayed
variation between and within families that were weakly
related to phylogenetic relationships and mainly related to
feeding niches. There was no evidence that any species used
vision to assist with the withdraw movement. Instead
strepsirrhines used mouth reaching to take food from the
hand and/or perioral contact to positioning food for biting.
Our findings support two hypotheses: that visual mediation
of food orienting for placement in the mouth during the
withdraw movement is an anthropoid innovation, and that the
evolution of the visual control of feeding was not a
singular event.},

indirect calorimetry for a variety of pre-cut and whole raw
foods varying in geometric and material properties. Net
feeding costs were determined in two ways: by subtracting
either the initial metabolic rate prior to feeding or
subtracting the postprandial metabolic rate. Interspecific
scaling relationships were evaluated using pGLS and OLS
regression. Net feeding costs scale negatively relative to
both body mass and jaw-adductor mass. Large animals incur
relatively lower feeding costs indicating that small and
large animals experience and solve mechanical challenges in

Anthropologists in North Carolina in 1996. The aims of this
symposium were to gather together the preeminent researchers
on mammalian mastication and document the state of research
in that field. The symposium emphasized in vivo studies of
mammalian feeding because of a paucity of recent reviews of
this field, but included morphometric and modeling papers as
well. Subsequently the papers were revised, and were
submitted in spring 1998 for publication, pending the
outcome of peer review. Copyright 2000 Wiley-Liss,

Title = {Fiber type composition of epaxial muscles is geared toward
facilitating rapid spinal extension in the leaper Galago
senegalensis.},

Abstract = {OBJECTIVES: We hypothesized that the vertical leaper Galago
senegalensis will have epaxial extensor muscles with a fast
fiber phenotype to facilitate rapid spinal extension during
leaping in comparison to the slow-moving quadruped
Nycticebus coucang. To test this, we determined the
percentage of fiber cross-sectional area (%CSA) devoted to
Type 2 fibers in epaxial muscles of G. senegalensis compared
to those of N. coucang. MATERIALS AND METHODS:
Immunohistochemistry was used to identify Type 1, Type 2,
and hybrid fibers in iliocostalis, longissimus, and
multifidus muscles of G. senegalensis (n = 3) and N.
coucang (n = 3). Serial muscle sections were used to
estimate and compare proportions, cross-sectional areas
(CSAs), and %CSAs of Type 1, Type 2, and hybrid fibers
between species. RESULTS: Epaxial muscles of G. senegalensis
were comprised predominantly of Type 2 fibers with large
CSAs (%CSA range ≈ 83-94%; range of mean
CSA = 1,218-1,586 μm2 ). N. coucang epaxial muscles
were comprised predominantly Type 1 fibers with large CSAs
(%CSA range ≈ 69-77%; range of mean CSA = 983-1,220
μm2 ). DISCUSSION: The predominance of Type 2 fibers in G.
senegalensis epaxial muscles facilitates rapid muscle
excursion and spinal extension during leaping, and is
consistent with their relatively long muscle fibers. The
predominance of Type 1 fibers in N. coucang epaxial muscles
may aid in maintaining stable postures during bridging and
cantilevering behaviors characteristic of slow-climbing.
These histochemical characteristics highlight the major
divergent locomotor repertoires of G. senegalensis and N.
coucang.},
