Document Summary
Only about 400 species: still, it is very diverse, there are many groups vested within others. Carpolestes simpsoni: earliest primate in the fossil record, has grasping digits and an apposable big toe with a nail rather than a claw, did not have binocular vision. Includes great apes and humans: subfamily is homininae. Includes gorillas, chimpanzees, and humans: tripe is hominini. Includes humans and our close extinct relatives: these changes are meant to reflect how closely related we are to the great apes. I meter tall: had teeth similar to modern humans, their brains were no larger than ape brains, about 35% the size of a modern human brain, one of the most famous fossils is a 40% complete. 11-9-16: there is a general belief that homo species evolved from a gracile. Africa: shows intermediate features similar to both homo and australopithecus, based on the skull shape, it was assigned to the homo lineage.
