Document Summary
*info from nova videos is testable will expand on info from lectures. Large brain size (encephalization) the instigator of the evolution. Habitual bipedal locomotion e. g. eoanthropus dawsoni (piltdown man) discovered by charles dawson. Claimed to have found the missing link between humans and ancestors skull was globular but prognathism existed. Claimed yes, it was large brain size that brought about human evolution, but turned out it was actually a modern homo sapiens and he had attached a baboon jaw and shaved teeth. **it is our bipedalism that drove our evolution, occurring end of miocene 6-7mya* Advantages of bipedalism bodies from waist down human-like for hominins. Contenders for earliest hominins: sahelanthropus tchadensis, chad 7-6 mya west africa. Unique features not seen on miocene apes: ardepithecus, aramis, ethiopia 4. 4 mya (reassigned to 5. 8-5. 2 mya) *must know by geography (west or south africa) and form (gracile or robust)*
