Today it’s an established fact that our skeletons are surprisingly malleable. The pure white remains displayed in museums may seem solid and inert, but the bones beneath our flesh are very much alive – they’re actually pink with blood vessels – and they’re constantly being broken down and rebuilt. So although each person’s skeleton develops according to a rough template set out in their DNA, it is then tailored to accommodate the unique stresses of their life.
This has led to a discipline known as “osteobiography” – literally “the biography of bones” – which involves looking at a skeleton to find out how its owner lived. It relies on the fact that certain activities, such as walking on two legs, leave a predictable signature behind, such as sturdier hip bones.
And from the discovery of a curious spiky growth on the back of many people’s skulls to the realisation that our jaws are getting smaller, to the enigmatic finding that German youths currently have narrower elbows than ever before, it’s clear that modern life is having an impact on our bones.
