Join these scientists on a journey to uncovering the mystery of the 'thigh gap.'

The thigh gap made its unwanted appearance around 2013, and just when we thought we’d heard everything there was to know about it, IT’S BACK.

This time however, we get a hilarious education into the thigh gap: otherwise known as one of evolution’s greatest mysteries.

Join these endearingly geeky scientists as they go one step further into uncovering the mystery of ‘dat gap.’

As one of the professors so aptly sums it up: “When we see something like the thigh gap in human evolution, we have to ask ourselves….why?”

So they may not be real scientists, but it’s still probably the one video about the thigh gap that actually makes the most sense.
