What if we told you that Santa's reindeer weren't who you thought they were, and that it's more likely that Donner went by Donna? And Rudolph is probably more of a Rudy.

That's right, according to science, Santa's reindeers are actually female.

The internet first came to grips with the news earlier this week thanks to a viral tweet about Kris Kringle's sleigh being pulled by a "team of strong, powerful, underrated women," due to the fact that male reindeer lose their antlers in the winter. Gasp!

A wildlife biologist confirmed the groundbreaking news in an interview with Inverse.

"Males shed their antlers in late autumn, and antlered females shed in early spring," she tells Inverse. "This has to do with the female's need to defend resources during pregnancy. Not all female caribou (reindeer) have antlers, but for Santa's crew to have antlers in December, they would be females."

And that's not all. Around the time of winter Santa makes his journey, male reindeer carry very little body fat—around 5 %— while females carry around 50% body fat in the winter, keeping them cold during the cold months. Therefore, female reindeer are better suited for Santa's long late-night haul around the globe.

You go girls!
