These traits include those related to the skeletal anatomy of the eye orbits, the number and types of teeth, and traits that relate to specific forms of locomotion. Ontogeny of the Postorbital Region in Tarsiers and Other Primates The bigger the social group, the more complex the social interactions, leading to the evolution of larger brains with more computing power, the theory suggests. Anthrop Anz 2:113135, Witzel U, Preschoft H (2004) The functional structure of the facial skull in hominoids. Individuals appear to benefit from group living, particularly when predation pressure is high, when females are sexually receptive, and when there is high likelihood of encountering a potentially infanticidal male. Brain size increased rapidly during human evolution due to the expansion of many brain regions, resulting in human brains being exceptionally larger than those of our closest relatives. 5. 2003.

Anterolateral ligament anatomy: a comparative anatomical study. Thanks also to Stacey McCarthy for assistance with illustrations, and to Tim Smith and Valerie De Leon for sharing their critically important evidence, and thinking, on the ontogeny of tarsier cranial morphology. Specifically, we propose that key postorbital traits, including the frontal spur in strepsirrhines and the posterior lamina of the zygomatic in anthropoids, develop as a result of the spatial relationships of brain, eyes, and teeth. Clipboard, Search History, and several other advanced features are temporarily unavailable.

(Gursky, 2002; Gursky-Doyen, 2010; Napier and Napier, 1985; Roberts, 1994), Young spectral tarsiers are precocial and receive only maternal care. Primates that have a postorbital bar as well as a complete bony wall behind the orbit (i.e., a fully enclosed orbit) have postorbital closure. We also describe and illustrate formation of the tarsier partial postorbital septum through the perinatal period using a growth series of Tarsius syrichta.

These arboreal quadrupeds live in small groups. Postorbital bar and postorbital closure A postorbital bar is a bony ring that forms the outside border of the eye orbit. Mothers sling offspring older than 3 weeks of age under their bellies while leaping and moving from tree to tree. Tarsiers also draw tourists to the Indonesian islands and are beneficial to humans financially as a form of ecotourism. They have long scaly tails with tufts of fur only present on the distal third of the tail. (Remember, this is a shared, derived trait that defines strepsirhines). Tarsiers have caused a lot of confusion for biological anthropologists because they share many traits with other haplorhines (the anthropoids: monkeys, apes, and humans), but they also share ancestral traits with strepsirhines. Though Sivapithecus was slightly larger than Ramapithecus, it was only a small-to-medium-sized ape about the size of a modern chimpanzee. Tarsiers are among the smallest known primates. Monkeys do not have the ability to see in the dark as most do not have the special eye adaptation called the tapetum lucidum. This structure is found in all primates.

To test these competing hypotheses while minimizing the confounding effect of tarsier orbital hypertrophy, we compared tarsiers and other primates at early (fetal and newborn) ages using dissection, micro-CT scans and soft tissue histology.
