"The science of paleoanthropology is famously contentious, but seldom do outsiders get to see the sausage being made.  Whatever your expectations, Don Johanson’s cleverly titled, uninhibited, and irresistibly readable new memoir will tax your eyebrow-raising musculature to the limit. This book is for everyone who cares about the ancient human past and has ever wondered how we know about it."

~ Ian Tattersall, author of Understanding Human Evolution
