2Stereoscopic vision
each eye takes a view of the same area from slightly different angles. can see where objects are in relation to our own bodies.
3Arboreal locomotion Hypothesis
Important to early primates to move efficiently and have good hand-eye coordination
4Visual predation Hypothesis
vision helps predators locate prey. suggests the diet of early primates was a predator
5Nocturnal vision hypothesis
Big eyes indicate hunting at night, early primates were hunting, and big eyes can take in more light
6Grasping Hands

8Carnivore
sharp teeth and pointed. Good for piercing, tearing, shredding
9Humans
flat molars, sharp canines
10Digestive tract
length is indicator of the main source of food
11Comparative anatomy
organisms share a common ancestor; classifying organisms
12Homologous structures
structures are similar in different species because they share a common ancestor
13Analogous Structures
structures are similar in different organisms because they evolved in a similar enviorment, not because of a common ancestor
