My guess is that genetics actually has determined the structure of all those axonal highways that are in place in our brains at birth. I think it quite reasonable to believe that that structure leads to male on female mating most of the time. How that happens exactly is what got me into neuroscience in the first place. My big questions is how do genes wire a brain to prefer a .7 waist to hip ratio across so many cultures. My guess now is that it does that indirectly because females have that ratio when they are by other conditions more likely to bear offspring. But who the hell knows for sure?
All we know is that this happens too damned much to be without mechanism.
Now, that is an interesting problem. How do genes code for a value judgment?
What is the historical value for that ratio? Has it held through time, or is it a contemporary style thing?

According to the literature it holds across 35 cultures and they seemed to be doing careful studies. Not sure how to do studies in time without some machinery. It is vexing. I mean how and the hell does a gene do that to an organism? Note that the waist size makes no difference, just the ratio. I would want to see the study on a tribe of men who had been raised without any contact with women at all. Then a tribe without any kind of language or sign.
