Despite deeply divisive issues like religion, politics, and Thin Mints versus Samoas, one common attribute follows every human: an ass. But why do we have butts? And why are they so much bigger than those of any other species on Earth? As a new video from DNews explains, the answer is pretty simple.
Turns out the human body's superior posterior is actually the key to our ability to balance while standing upright, according to the video. As DNews host Jules Suzdaltsev explains, most living organisms possess some type of anus for the purpose of pooping, but no other creatures on the planet are blessed with big butts -- let alone the level of booty described by Sir Mix-A-Lot. Unlike our primate neighbors, humans evolved to form uniquely-placed gluteal muscles that allow us to do things like stand up, walk up stairs, and stand still while completely upright.
