Document Summary
The living primates: despite the sa(cid:373)e (cid:271)asi(cid:272) adaptatio(cid:374)s, still a lot of di(cid:448)ersit(cid:455) , morphological, ecological, and behavioral diversity, morphological- sizes, ecological- different places around the world, behavioral- nocturnal primates vs ones active during the day. Mammal radiation: divided mammals into 3 different groups, metatheria, marsupials, prototherian, platypus- ones that lay eggs, eutheria, placentas, uterus mammals. No, they just prospered after the dinosaurs died. Geographical distribution of living nonhuman primates: chart of the world. Extremities adapted for prehension: opposable thumbs and big toe(ish) (owm, apes, humans, pentadactyly- 5 digits, flat nails, exceptions. What makes a primate: olfactory apparatus reduced, stereoscopic vision, binocular vision, color vision, fovea centralis, central pit in the retina that lets us focus on something and still see stuff outside of that, slow reproductive rate. Large brain: homeothermy- constant body temperature, specialized skeleton. Modern primate and non-primate skulls: picture of different skulls.
