The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
The Effects Of Diet, Size, And Phylogeny On Primate Dental Proportions, Rudolph J. Wilkins
Graduate Theses and Dissertations
It is generally appreciated that there is a relationship between the relative size of the incisors, mandible length, and diet in primates. More specifically, the differences in relative incisor size among primate species are believed to be evolutionary adaptations to their use during food processing and acquisition. While this satisfactorily explains relatively large incisors, it fails to address the relatively small incisor size seen in many taxa. One hypothesis is that there is a trade-off between molar size and incisor size in species with relatively short mandibles. The following study uses two-way ANOVA to evaluate the possibility that spatial constraint …
Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Sacral Morphology Of Prehensile-Tailed Primates In Relation To Biomechanical Loading, Hannah Grace Showalter
Graduate Theses and Dissertations
The few available comparative studies of prehensile tail anatomy in primates have established that several features of the caudal vertebrae are associated with adaptation to the increased loading of the tail during prehension. Given that the caudal vertebrae are anchored to the sacrum, it stands to reason that sacral morphology should also covary with tail prehensility. Convergent evolution of prehension in ateline and cebine primates and clear variation in the use of tails among taxa raises questions not only of how sacral morphology differs between prehensile and non-prehensile taxa, but whether different prehensile-tailed taxa evolved the same solutions to the …
