Can I just say/rant one thing that always irritates me about Venus figurines and art with respect to sexuality/repro in the past is the conceit that saying "they were concerned about reproduction, or it was a focus" whatever is somehow supposed to be an interesting observation. Tell me about a culture that doesn't have some concern, taboos, mores about reproduction, etc. for god's sake. Other than sexy sexx sexxy sex-time sex sex sex titillation, what is so interesting about it? Hey, did you know that faunal remains indicate that people in the past ate food? No, listen, they literally ate food, with their mouths.
And, really, I couldn't agree more: To state that Venus figurines are evidence that Upper Paleolitic folks people cared about sexuality is kind of ridiculous. Of course they did in one way, shape or form, - and we certainly don't need Venus figurines to determine this.
Still on the topic of the paleo-porn story, also make sure to check out Becky Farbstein's post about the story - it touches on a lot of the same issues I originally raised.
