Evolutionary psychology investigates the adaptive function of human cognition, emotion, and behavior. The approach equips psychologists to describe the human mind in a way that is consistent with revelations in biology, ecology, and genetics, without ignoring the unique influence of personal and cultural factors. Shaped by natural selection, the brain has narrow and flexible capacities as an organ of the animal body; it consists of modules specialized at solving adaptive problems that recurred in the ancestral environment. In understanding the cooperation and contradiction of these systems, evolutionary psychologists seek to better describe the design of the animal mind.

Evolutionary principles have played a central role in our understanding of non-human sexual behavior for 150 years. Over the past 40 years, research has accumulated that demonstrates the applicability of evolutionary principles to human sexual attractions and behaviors. My research and expertise draw upon this literature and the diverse individual and cultural factors that influence male and female sexuality development and expression. A fully modern understanding of human sexuality requires the synthesis of evolutionary foundations, environmental inputs, and individual variation.
