Perhaps much of the controversy about evolutionary psychology devolves from forgetting some basic biological definitions. The gene is the unit of inheritance, which has a complex and imprecise relationship with the mature, viable organism that has inherited it. The unit of evolution is the individual organism. Therefore, the arguments about what is more important in evolution are specious. Since “survival of the fittest” is actually an ecological phenomenon that occurred in the distant past under conditions that cannot now be duplicated, we will never prove which genes mattered most then for any given species.
