Supercooperators

In their new book "Supercooperators," Morris Novick and Roger Highfield state that "most of the great innovations of life on earth, from genes, to cells, to societies, have been due to the "master architect" of evolution: cooperation."  Figuring out how cooperation comes about and breaks down is the key to our survival as a species.  They also stage that: language, cognition morality, and the division of labor are evolutionary spin offs of the fundamental need of social creatures to cooperate; and that cooperation can prevail if altruists cluster together.
