The bone is a miracle. It is a strong and adaptable building material that has been around for over 500 million years of evolution. Perhaps no other part of the human body has such scientific and cultural significance. The bone is filled with life, and at the same time it is a well-known symbol of death. Brian Switek talks about bones with charm and enthusiasm. In this book, he explains how our skeleton came to be, what its functions are, and what our descendants will be able to learn about us when these amazing accumulations of minerals and protein are all we leave behind.
