There is little doubt that there is an abundance of evidence regarding the role of cooperation among social animals and it is mentioned here as a precondition for the discussion of group selection and altruism; specifically in humans.
While many of the elements that constitute human behavior are present in other animals, there is little question that humans represent an extremely unique existence. Beyond even the obvious differences regarding intellectual capacity, humans represent a
eusocial mammal that exploits an extreme division of labor, such that it is human society that operates to support human existence, rather than the capabilities of any individual (1).
