ANT211H5 Lecture Notes - Lecture 2: Sociobiology, Ontogeny, Heredity
Document Summary
Darwin the idea that there is variation in every population competition no one is identical variation between individuals o o some will be successful in their reproduction and some will be less successful. Where animals vary, and where those variations are at least partly inherited, the less successful varieties will be eliminated, and the more successful will become relatively numerous. Offspring must reach sexual maturity and go on to reproduce. A successful organisms traits must be passed on to descendents. Key to reproductive success: create offspring and that they reproduce. The study of behavior based on darwinian paradigm formed in 1970s, by e. o wilson o o biologist who studied ant behavior and genetic populations ants are related to their genetics. Natural selection allows us to answer to why questions of human behavior. 4 explanations to answer why in biology: proximate causation. Concerns the direct mechanisms that bring something about. Physiological explanation of why something happens e. g. blood.
