Origins of the human brain and behaviour. Questions addressed by studying nonhuman animals: understanding brain mechanisms. Uses cross species comparisons: human neurological disorders. Researchers produce a models of human neurological disorder an in animal. Cause and treatment for the disease can be examined through manipulation of variables. Humans today are the only surviving member of the hominid branch: human evolution. Studied through archeological, biochemical and genetic, and behavioral evidence.
