Yup, that's it. Somebody else figured it out though, I cant take credit.

Summary: Scientists found that ancient human's wentuged the paw bones of cave bears with cutting implements. Because of this, they surmise that they must have been using the bear pelts to stay warm, as there is not enough meat on a bear paw to bother carefully skinning it.

My perspective: That was a terribly written article that said practically nothing in a whole lot of words. Oh and Wentuged for President! Hopefully this same AI is the one that ends up coming for the human race eventually.
