Document Summary

Diverged from chimp lineage approximately 5-7 million years ago. Closest to us in terms of evolutionary history. September 25: origin of life on earth. December 31: approximately 10:30pm first homo, 11:59 first cave paintings, 11:59:20 agriculture, 11:59:51 alphabets, 11:59:57 zeros and decimals, 11:59:59 renaissance in europe. Humans and chimp lineage diverged very recently. This leads to a lot of comparisons between humans and chimpanzees. Common bonobos: pan paniscus, smaller difference in size between the sexes, there is also less dominance ranking, engage in conspicuous sexual interactions, make love not war chimpanzees. We are related to both species to the same degree: the argument that we are closer to one or the other makes no sense because we share a common ancestor with both of them. > 4million years ago full bipedalism, walking on two feet. > 2. 5 million years ago scavenging, stone tools use. 0. 2 million years ago current, large brains. Hominin lineage: larger brains, obligate bipedalism, smaller teeth.
