Good point about the c-sections, but still, I am not entirely convinced. For one thing, that wouldn't explain waist/hip, or would it? It would then all be hip, and women would get increasingly larger hips? Also, thinking about Asia, I think women are very tiny there, and they still get children. Their babies are probably smaller, too. But making bigger and bigger babies does not seem to be a "goal" of evolution, either. Otherwise a woman's height would be attractive, which I don't think is the case.
