Likely, but this is probably more the basis for the ones we know of into history than anything. We can still see some signs of this here and there, so most likely the case.

Interestingly we don't get any statues proper until the Upper Paleolithic, and the oldest one we have is a therianthropic figure. Depictions of humans in cave art are pretty rare throughout the Paleolithic and even after that, it is nearly all animals and the occasional half-man half-beast figure as well.
