Every human being arrives in the world with a skeleton that is, by design, unfinished — roughly 270 bones, many still soft cartilage, where an adult will eventually carry 206. This is not incompleteness but ingenuity: evolution's answer to the profound tension between a large-brained species and the narrow passage through which it must enter the world. Over the course of childhood and into early adulthood, the body quietly resolves this tension, fusing and hardening until the skeleton settles into the durable architecture of adult life.
