Why Do Humans Have Butt Hair?

Despite being the least hirsute hominin, humans have retained a fair amount of hair in our most intimate regions, including our butt cracks.

However, while the hair on our heads, in our armpits, and around our sexy bits serves a number of obvious functions, scientists still don’t have a definitive explanation for our bewhiskered backsides.

To try and shed some light on the mystery, SciShow set their crack team of investigators on the case, revealing their findings in a video that has already been viewed by over 4 million people who clearly feel the need to understand why they possess hair on their rump. Unfortunately, however, very little scientific research exists on the subject, which means it’s only possible to speculate on the purpose of our tufted tail-ends.
