ANT101H5 Chapter Notes - Chapter 9: Apidium, Simian, Aegyptopithecus
Document Summary
Debated actual primates vs member of close but different group of mamals. Eocene (56-33 mya)= closer connections to living primates. Widely distributed mostly extinct by end of eocene. Possible roots of anthropoids -> apidium ( lie near evolutionary divergence, arboreal quadruped traits, severaldotun jaws/partial dentitions) aegyptopithecus- bridges gap between eocene and. Miocene (23-5 mya)= closer to apes and humans. European forms derived + varied evolutionary similarities because of homoplasy. Asian forms- largest and most varied highly derived. 4 general points miocne =hominoids (closer to apes than old world monkeys_ Very derived therefore not ancestral to any living form. Hominins derived sometime in later miocene= bipedalism. = characteristics of bipedalism larger brain size toolmaking behaviour. Mosaic evolution = evolution rate of different functional systems at different times. Advantages -> freed hands for carrying objects, wider view of surrounding, cover great distances.
