There is a discovery channel documentary about beauty which talks about how they think symmetry is partly determined by the fetal environment. Each half of the body grows at the same time--mirror-like, so changes in nutrition or stress can impact the one side or the other. The theory they developed based on this information is that selection for symmetry is really just expressing a preference for a mate who is more likely to be in better environmental circumstances than a less symmetrical mate. If this is true, it would make sense that woman (and men) in general are more symmetrical today than they have been in history. Nutrition, disease and stress (from violence especially) are much better for larger numbers of people.
