PSY311H5 Lecture Notes - Lecture 2: Sociobiology, Natural Selection, Twin
Document Summary
This means it is really important to our own survival. Natural selection: organisms are well equipped to cope with environmental challenges to: we have the genetic material to make sure we have what we have to continue to. Genetic endowment: biological structure we receive for this purpose. The most fit species to meet environmental challenges are the ones that will ultimately: as environments change some specifies are better and some are worse, this is between species. Extension of evolutionary theory to social behaviour. An attempt to organize the facts about the adaptive significance of social behaviour in animals and by extension, in human beings. Ex: parenting behaviours (harder for moms to be away from newborns than dads) Three aspects of evolutionary theory must be emphasized: Evolution concepts apply as much to behaviour as to structural characters: not just gills and lungs, but behavior as well, we can only infer behaviours origins though.
