I agree with a lot of what Paul Carter said about physical beauty, but I do believe he is underestimating the role culture plays. Yes, on a basic level, we are genetically programmed to be attracted to the physically fit, but at the same time, the standards of beauty can be fudged by cultural requirements. When rich people spent most of their times indoors and poor people indoors, white skin became preferred over tan, but when poor women's jobs moved indoors (factories, clerking in stores) and rich women took up tennis and laying around on beaches, tan skin became more fashionable. As a overweight man who has lived in America, England, Vietnam, and China, I can also tell you that the harder it is for a woman to find a good man with a good job, the less she cares about some extra pounds, but at the same time, in America I found I did all my dating when my chest stuck out further than my belly. Growing up in a capitalist, urban society but with bodies that evolved in the wild causes complications to the attractiveness equation.
