I was reading over Esther’s shoulder as she read the ridiculous NRx article that this quote was from, and right after that quote was possibly the worst evolutionary just-so story I have ever heard:
Thousands of winters of scarce, sparse prey and harsh terrain culled a significant percentage of men. Lack of easy gathering opportunities neutered the production capacity of women, forcing them to depend on the remaining men for food sources. As men could no longer resort to a fuck and chuck breeding strategy because their children wouldn’t survive in a dearth environment solely on the efforts of the mother, heavy male parental investment emerged as Darwin’s winning gene, keeping the oversupplied ratio of spermatazoa to ovum in deadly check. As men invested heavily in their mates, they chose fewer of them. Pressure laid on women to capture a man’s attention and sweat for a long time, not just for the three and half minutes needed to obtain his genes. Geographic isolation prevented interbreeding with other races less adapted to beauty.
The ugly women went barren and beauty flourished.
The writer here is (as he clarifies later) talking specifically about Scandinavian winters, which he thinks produced uniquely beautiful women, which, OK, let’s just sidestep all that because –
He’s saying that women became really physically attractive in order to attract long-term male parental investment, rather than just the sexual attraction necessary for copulation?!?!?!!
Like the usual critique of evolutionary hypotheses like this is that all the details are underdetermined by existing evidence, making it possible to paint in whichever details are necessary to come to whatever conclusion one has in mind. But this one doesn’t even paint in the right details!

ETA: this seems to be standard ev psych (see Trivers), so I guess the egg’s on my face.
