The Shape of Things to Come?

Marginal Revolution observes:

The Environmental Security Hypothesis says that in tough times men will prefer women who are good at production, generally older, taller, heavier, less curvaceous women with less body fat. In good times, they will prefer women who are good at reproduction, generally younger, shorter, lighter, more curvaceous women.

Of course, it just may be that beauty is in the eye of the optimist.
