Peter Gray has a passion for understanding various aspects of human behavior and physiology, especially in the realm of reproduction, from an integrative, evolutionary perspective. That is a sensible scholarly passion too: In a Darwinian world, the ultimate currency is reproductive success.

In practice, this means focusing on features of human fatherhood, sexuality, partnerships, and more, while situating a topical focus within evolutionary and life history theory, comparative animal research, cross-cultural patterns, and physiological processes. This is an inherently interdisciplinary and scientific approach but also well situated within anthropology, given the field’s appreciation for our primate kin, cross-cultural emphasis, and overarching evolutionary perspective.
