A Stone Age person buried 12,000 years ago in a cave in Italy had a rare genetic disorder that shortened her arms and legs, a new study finds. A DNA analysis of her skeleton revealed that she was a teenage girl who had a rare form of dwarfism. The finding is the earliest DNA diagnosis of a genetic disease in an anatomically modern human, the researchers said. She was buried in an embraced position with an adult nicknamed "Romito 1," who was also interred in the limestone Romito Cave in southern Italy. Romito 2's diet and nutritional condition were similar to those of the other people buried in Romito Cave, suggesting that her community looked after her.
