Your face may have been sculpted by junk DNA

Even the prettiest faces are built using junk. In mice, the shapes of the face and skull are finely tuned by junk DNA, so called because it was initially thought to lack function since it doesn't encode proteins. The same junk DNA sequences are found in humans, so they are probably also shaping our faces.

This finding could help us make sense of some congenital conditions, such as cleft palates, that can develop even when the genes that shape the face appear to be working normally
