Of course, I will offer an official apology to the Cro-Magnon people, if evidence comes to light that they, actually, invented twerking.
Interesting thought Tim and I've seen some Aboriginal spirit dances that look a lot like twerking! Maybe she saw them too! Also, it's well known now among paleoanthropologists that speech development is a key factor in hunting and orally recording future hunting sites as well as cooperation among the hunters. That's partially what made us better hunters and survivors than our Neanderthal cousins. CT brought up some important points as well and all of these evolutionary alterations aided our immediate ancestors in the struggle for survival. BTW it looks like then"out of Africa" theorists are winning the argument as more info comes to light.
