This could get hairy: A new study from scientists at the University of Utah and University of Pittsburgh, published in the journal eLife, shows that a set of genes and regulatory regions of the genome appear essential for making hair. And it seems humans actually have the genes for a full coat of body hair, but the researchers believe evolution simply “disabled them.”

“We have taken the creative approach of using biological diversity to learn about or own genetics,” Nathan Clark, a human geneticist now at Utah and a study coauthor, says in a news release. “This is helping us to pinpoint regions of our genome that contribute to something important to us.”

Exploring why some mammals have much less body hair than others led the group of three researchers to start comparing genetic codes from 62 animals. The scientists believe their study shows how regulatory regions of the genome influence the hair-growing process indirectly, guiding when and where certain genes turn on and just how much hair is made.
