The theory of evolution and Neo-Darwinian biological theory extend their analysis in sociobiology from the life sciences and the animal societies to human societies. Sociobiology as a unifying theory of the social interaction within and between species has led to an integration of economic analysis into biology. The economy of nature has become the subject of bioeconomics which in turn transferred biological analysis to the human economy. Evolution, competition, selection, and cooperation are phenomena common to the economy of nature and human economy. The inclusion of economic and cultural theory in evolution theory raises the question whether the Neo-Darwinian Synthesis with its exclusive concern with somatic heredity is able to incorporate developmental systems of the human economy and of cultural heredity. A new synthesis of the natural and the social sciences is in the making.
