In 1971, he published The Insect Societies, which argued that insect behavior and the behavior of other animals are influenced by similar evolutionary pressures. In 1973, Wilson was appointed the curator of entomology at the Harvard Museum of Comparative Zoology. In 1975, he published the book Sociobiology: The New Synthesis applying his theories of insect behavior to vertebrates, and in the last chapter, to humans. He speculated that evolved and inherited tendencies were responsible for hierarchical social organization among humans. In 1978 he published On Human Nature, which dealt with the role of biology in the evolution of human culture and won a Pulitzer Prize for General Nonfiction.
