A gene tied to facial development hints humans domesticated themselves

Called BAZ1B, it may also help explain why domesticated animals look cuter than their wild kin

Modern humans (left in this illustration) have flatter, smaller faces than Neandertals (right) did. Now researchers are implicating a gene that affects movement of some developmentally important cells in that change.

Domestic animals’ cuteness and humans’ relatively flat faces may be the work of a gene that controls some important developmental cells, a study of lab-grown human cells suggests.
