Good news, maybe, if you dig on androgyny—researchers at North Carolina State University say that the faces of men and women are much more alike now than they were just a couple of hundred years ago. They’ve figured this out by examining about 250 skulls from Spain and Portugal that date from the 1600s to the present day.

According to experts, better diet and environmental factors caused the changes. In particular, the facial structure of women has changed and become noticeably larger than their older counterparts.

The team focused in on the differences between men and women because it could “help us establish the sex of the remains based on their craniofacial features,” said lead researcher Dr Ann Ross, an anthropologist. We knew there had to be a science-y reason. We were hoping for something that explained look-alike celebrity couples, but that will have to wait for a sexier study.
