Document Summary

More similar to humans in the upper and mid face: nose does not jut out, non prominent brow ridge, close orbits. Humans are more related to chimps and gorillas. Lineage of orangutans split off 12 16 mya: gorilla: 6 8 mya, human and bonobo/chimp: 4. 5 6 mya. The closer we get to the 5 mya period, the more we can identify what our common ancestor looked like. Late miocene: the number of apes dropped drastically and the old world monkeys became the most numerous because they were the most successful at adapting. Africa: 24 mya ----------- 12 mya: evidence, good fossil record, 12 mya - - - - - - - 6 mya: no fossil evidence, hominoid gap. Eurasia: 24 mya - - - - - - - 16 mya: no evidence, 16 mya ----------- 6 mya: decent fossil record, 6 mya - - - - - - - - 2. 2 mya: stops.
