Head to tail: the molecules that tell you how to grow a backbone

Growing the right number of vertebrae in the right places is an important job – and scientists have found the molecules that act like ‘theatre directors’ for vertebrae genes in mice: telling them how much or how little to express themselves.

The finding may give insight into how the body-shapes of different species of animals evolved, since the molecules under scrutiny are present in a wide range of animals – ranging from fish to snakes to humans.
