It’s the dance move that’s taken the world by storm: twerking.

According to the Oxford Dictionary (that’s right, freakin’ Oxford Dictionary!), to twerk is to “dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance.” A.K.A., it’s the dance move that took Miley Cyrus from an innocent little girl, to a naughty little girl.

Well, we decided to get an expert’s opinion on the new dance craze. No, we didn’t ask a musician, or a dancer, or even a DJ about the dance, we asked our favorite scientist from our childhood, Bill Nye The Science Guy (Bill! Bill! Bill!).

There you have it; twerking is a part of Evolutionary Biology. Science rules!
