The Social Conquest of Earth

April 30, 2012

It seems that blood may not be thicker than water after all. Today on Focus, we're joined by renowned biologist Edward O. Wilson, who in his new book The Social Conquest of Earth claims that human evolution has not been driven by kin selection, but by group selection—meaning that we are not naturally predisposed to put family first. He'll discuss this and more on today's show.

Guest: Edward O. Wilson, Ph.D. (Emeritus Pellegrino University Research Professor of the Department of Organismic and Evolutionary Biology, Harvard University; author of The Social Conquest of Earth).
