What are the differences between primates and mammals?
What are some of the major primate anatomical characteristics and how are they explained via both the arboreal hypothesis and the visual predation hypothesis?
The arboreal hypothesis proposes that defining primate characteristics were adaptations to life in the trees such as: grasping hands and feet developed vision and greater intelligence. The visual predation hypothesis proposes that: primate traits arose as adaptations to preying on insects and small animals.
