Bone is a marvel, an adaptable and resilient building material developed over more than four hundred million years of evolutionary history. It gives your body its shape and the ability to move. It grows and changes with you, an undeniable document of who you are and how you lived. Arguably, no other part of the human anatomy has such rich scientific and cultural significance, both brimming with life and a potent symbol of death. In this delightful natural and cultural history of bone, Brian Switek explains where our skeletons came from, what they do inside us, and what others can learn about us when these artifacts of mineral and protein are all we've left behind. Bridging the worlds of paleontology, anthropology, medicine, and forensics, Skeleton Keys illuminates the complex life of bones inside our bodies and out.
