Document Summary
Gives only living model for human ancestors. Experimental = pro = spec var can be ctrl. Pro = better pic of beh, more rewarding. Prim share number of traits considered to be shared by common. Some traits evolved + changed from common ancestor = derived traits. Rel to other non mam vertebates, mam gen have hair. Hard to determine if trait is ancestral or derived many ways groupings for each. Tendency for large brain rel heavy in prop to body weight. More complex brains gives ability of thought (greater) Large brain accomodates more reliance on vision compared to. Colour vision - eg. look at tree know when ripe and know when to eat. Stereoscopic vision gives depth perception eyes. Positioned forward = binocular gives better focus on. Objects gives overlapping visual fields gives us depth. Perception more dev in anthropoids vs persimeons. Grasping toes as well as hands (opposable big toe) Flexible limb structure wide range of locomotor beh as.
