PSYB65H3 Lecture 2: PSYB65 Lecture 2 Notes | Evolution & Neuroanatomy Structure
Document Summary
Evolution of ourselves, total whole: darwin: scientific explanation on the variety of spp. (cladogram of origin of humans, theory: share more dna w/ chimpanzees vs. other primates. Brain evolution: cerebellum relatively old structure, present in frog, fish, bird, human. Uses cross spp. comparisons: human neurological disorders. Researchers produce models of human neurological disorders in an animal. Evolution: progressively changing: hominid evolution, evolution = not linear, humans today = only surviving member of hominid branch, human evolution, studied through archeological, biochemical & genetic, behavioural science. Examine the bones, skulls, habitat of hominids to reconstruct features of their brains & behaviours. Looking at the brain: shape, inside of cranium (shape), volume. Small changes overtime, regularly: gives idea of when we actually diverged from a spec spp. Behavioural research: compares behaviour of one spp. to another spp. Jane goodall: observed behaviour in chimps: chimpanzee behaviour similar (less sophisticated, non-verbal communication, etc.
