Pat Shipman is a paleoanthropologist specializing in human evolution and a well-known writer of books and articles for the general public about evolution and human biology. Her 1994 book The Evolution of Racism: Human Differences and the Use and Abuse of Science traced the complex interaction of genetics, anthropology, and racism from Darwin's day to the 20th century. Now retired from the anthropology department at Penn State, Shipman in 2015 published her 10th book, The Invaders, in which she argued provocatively that the Neanderthals were eradicated by modern humans hunting cooperatively with dogs — 20,000 years before wolves were thought to have been domesticated. Shipman is a Fellow of the AAAS and in 2006 was awarded the Leighton Wilkie Prize by the Stone Age Institute at Indiana University for her lifetime contributions to paleoanthropology. A long-time contributor to American Scientist magazine, she has also won several literary prizes and in 2000 was selected as the A. Dixon and Betty F. Johnson Lecturer in the Communication of Science at Penn State.
