Baby Got Swayback

There’s a new(ly identified) attractiveness standard by which women are relentlessly judged for sexual, romantic, and yes, marital worth: The swayback. Reader Experienced Father passes along the relevant study.

This paper reports independent studies supporting the proposal that human standards of attractiveness reflect the output of psychological adaptations to detect fitness-relevant traits. We tested novel a priori hypotheses based on an adaptive problem uniquely faced by ancestral hominin females: a forward-shifted center of mass during pregnancy. The hominin female spine possesses evolved morphology to deal with this adaptive challenge: wedging in the third-to-last lumbar vertebra. Among ancestral women, vertebral wedging would have minimized the net fitness threats posed by hypolordosis and hyperlordosis, thereby creating selective pressures on men to prefer such women as mates. On this basis, we hypothesized that men possess evolved mate preferences for women with this theoretically optimal angle of lumbar curvature. […]

Men again tended to prefer women exhibiting cues to a degree of vertebral wedging closer to optimum. This included preferring women whose lumbar curvature specifically reflected vertebral wedging rather than buttock mass. These findings reveal novel, theoretically anchored, and previously undiscovered standards of attractiveness.

The optimal swayback looks like the middle female silhouette:

The woman with no swayback too closely resembles a prepubescent boy. The woman with excessive swayback looks like a scoliotic whore who spent too may nights leaning into the open car windows of johns. The woman in the middle is juuuuuust tight.

It’s theorized that women with a 45 degree curvature of the lower spine are best adapted for squatting on their haunches and foraging for food. Over time, men would’ve come to prefer this female body shape because it indicated better fitness at the job of gathering nuts, berries, and other huthold objects.

I don’t know if this study controlled for race, but I bet one that does would find that the male preference for swayback is more cross-racially universal than is the male preference for bloated booty, which black men favor more.

Anyhow, more lab confirmation of the CH formulations based on real-world observations that biomechanics is god, love is a tender effusion stimulated in men by small adjustments in the geometric contours of the female face and body, and feminists are butthurt loons.
