So evolution has determined the characteristic of humans. So evolution determined behavior of organisms. Long limbs (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) (cid:1) Lots of possibilities: bipedalism, fire, speech, diet change, savannah living . Adaptationism is talking about all biological features as though they are for something. A particular story might not be falsifiable. Mircocephalin evidence of positive selection (4000-5000 years) We can look at a certain region of dna, and is africans and. People assume that this means one region is smarter because of this variation (but this is inconsistent) Brain size is unchanged over 35 000 years. H. sapiens has a larger brain wrong neanderthals actually had a bigger brain. More complex behavior (tools, art, trade ) extended phenotype ; archaeological evidence.
