Forming a twenty-first-century statement on Darwinian evolution, one shorn of “religious and political dogma,” Edward O. Wilson offers a bold work of scientific thought and synthesis. Asserting that religious creeds and philosophical questions can be reduced to purely genetic and evolutionary components, and that the human body and mind have a physical base obedient to the laws of physics and chemistry, Genesis demonstrates that the only way for us to fully understand human behavior is to study the evolutionary histories of nonhuman species. Of these, Wilson demonstrates that at least seventeen?among them the African naked mole rat and the sponge- dwelling shrimp?have been found to have advanced societies based on altruism and cooperation.
