Document Summary
Species heredity - the genetic endowment that members of a species have in common, including genes that influence biological maturation and aging processes. Species heredity is one reason certain patterns of development and aging are universal. There is genetic variation in a species. Some genes aid adaptation more than others do. Genes that aid their bearers in adapting to their environment will be passed to future generations more frequently than genes that do not (natural selection). Evolution is about the interaction between genes and environment. Evolutionary psychology - the application of evolutionary theory to understanding why humans think and behave as they do.
