There's more to this unbuttoned and intellectually playful book than its plea for a conservation of ethic and the preservation of animal species in all their diversity. We get, for example, several autobiographical glimpses into the background of Professor Wilson...We see Professor Wilson as a boy growing up in the Florida panhandle...Elsewhere he astonishes us with a description of the mating dance of the male Emperor of Germany bird of paradise, and the degree of genetic congruity between pygmy chimpanzees and Homo Sapiens.
