David Barash, professor of psychology at the University of Washington, is the author of over 20 books (among them Natural Selections, The Myth of Monogamy and Madame Bovary's Ovaries) and over 200 articles. One of the earliest proponents of "sociobiology" in the 1970s, now know as "evolutionary psychology" or "evolutionary biology," he remains among its most articulate popularizers. Judith E Lipton earned her MD from the University of North Carolina at Chapel Hill. She met David Barash in 1975, in Seattle, Washington, and they were married in 1977. Her collaboration with Dr. Barash led to a shift in focus, to evolutionary psychiatry. Together they have published 6 books including "The Myth of Monogamy" and "Gender Gap."
