Unlike the other founders of sociobiology, Trivers was more interested in human than in animal behavior. The founding genius of sociobiology, Bill Hamilton, was a naturalist and romantic who felt himself ill at ease in the modern world, and had a passion for insects, especially wasps. EO Wilson loves ants and arranged his office at Harvard so that there were ant colonies in Perspex all around the walls, and the visitor might think he was inside a gigantic ants’ nest. Wilson added one final chapter on humans to his book Sociobiology almost as an afterthought, though this caused a bitter feud that has divided the Harvard biology faculty to this day. Trivers, however, started his theories from what he could observe of human behavior, and then went looking for genetic causes whose logic would apply across the whole living world.
