From a description of his new book:
In Why Is the Penis Shaped Like That?, the research psychologist and award-winning columnist Jesse Bering features more than thirty of his most popular essays from Scientific American and Slate, as well as two new pieces, that take readers on a bold and captivating journey through some of the most taboo issues related to evolution and human behavior. Exploring the history of cannibalism, the neurology of people who are sexually attracted to animals, the evolution of human body fluids, the science of homosexuality, and serious questions about life and death, Bering astutely covers a generous expanse of our kaleidoscope of quirks and origins.
Jesse is also the author of The Belief Instinct: The Psychology of Souls, Destiny, and the Meaning of Life. He recently filled in for Savage Love. Previous videos of Jesse here and here. “Ask Anything” archive here.
