The ferocious 1975 backlash against
Wilson's attempt to apply
evolutionary biology to human social behavior — a case study in how disciplines punish boundary-crossing.
Wilson's 1975

The book's first twenty-six chapters, covering insects through mammals, were received as a landmark contribution. The twenty-seventh chapter, which tentatively extended the framework to human beings, provoked a response so violent it included physical assault: a pitcher of water poured over Wilson's head at the American Association for the Advancement of Science meeting in 1978, accompanied by chants from demonstrators.

They were social scientists, humanists, and biologists aligned with specific political commitments that Wilson's framework appeared
