ANTA01H3 Lecture Notes - Lecture 3: List Of Fossil Primates, Postorbital Bar, Simian
Document Summary
Grasping extremities hand is good for holding/grasping things. Human feet cannot grasp but some primates can. Differences b/w squirrels foot and primate"s foot: squirrels have claws and no opposable big toes. Relatively large brain to their body size in comparison to other mammals. Primates are eyes-first animals, whereas dogs are nose-first. Primates have smaller noses than other mammals (e. g. horse). Eyes face forward (convergence) rather than on the side. First-eye: we use our eyes first when we observe something we don"t know. Dogs however, use their nose and sniff around to learn about something. Brain can take input from both eyes and get information on distance and get the 3-d shape of reality (visions overlap, stereoscopic versions). E. g. horse sees through parallax (put finger in front of your face, and close one eye alternatively and your finger. Horses cannot see things that is right in front of them.
