R. McNeill Alexander is renowned for his biomechanics textbooks, but in Human Bones (Pi Press, $37.50) he provides a tour of the 213 bones of the human skeleton for a general audience. He explains how our skeletons form and function, and how knowledge of individual differences assists forensics and archaeology. Accompanying the text are stunning photographs, like this one of a Chinese woman's bound foot, taken by Aaron Diskin.
