Today we have relatively few hominoid groups:a. Hylobatesb. Pongoc. Gorillad. Pane. Homov. What happened to all the apes?a. Global cooling restricted forested environments to the tropics. This trend began in the mid-Mioceneb. In the more open habitats, apes were unable to compete with the cercopithecoidsII. Humansi. Extant hominoids:a. Derived human traits1. Ovligately bipedal2. Small canines3. Large brains4. Broad dietary niche and tool use5. Extended time to maturityii. When did great apes and humans diverge?a. 5.5-7 myaiii. What would we expect the earliest hominin to look like?a. They would not look like living humans1. We would expect them to look “ape like”2. The spritting of the chimp and human lineages 6-8 mya would not have entailed a dramatic adaptive shift for the earliest hominin3. BUT While we might expect these early hominins to share some features with living chimps, the chimp lineage has continued to evolve after it split from humans, just as humans have
