David C. Lahti is an Associate Professor of Biology at Queens College, City University of New York, where he runs a Behavior & Evolution laboratory focusing mainly on learned behavior in birds and humans. Prof. Lahti received a BS in biology and history from Gordon College. He received a PhD in moral philosophy and the philosophy of biology at the Whitefield Institute, Oxford, for a study of the contributions science can and cannot make to an understanding of the foundations of morality. He then received a PhD in ecology and evolutionary biology at the University of Michigan for a study of rapid evolution in an introduced bird. He has been a Darwin Fellow at the University of Massachusetts and a Kirschstein NRSA Research Fellow with the National Institutes of Health, where he studied the development and evolution of bird song. His current research projects include rapid trait evolution following species introduction, cultural evolution in humans and animals, and the evolution of our capacity for morality and religion.
