The Echoes of the Mind (74-1-1) Back Story

 Back Story

Men are known for admiring women’s busts and behinds. Both are indicative of childbearing and child-rearing qualities. The breast assessment is obvious, but for the derriere, there is an angle to the appreciation.

Men prefer women who exhibit specific angles of spinal curvature over buttock mass. ~ American psychologist Eric Russell

A 45.5° incline from rump to spine is most attractive to men, and, not coincidentally, provides the ideal angle to let pregnant women balance their weight over their hips.

These women would have been more effective at foraging during pregnancy and less likely to suffer spinal injuries. In turn, men who preferred these women would have had mates who were better able to provide for fetus and offspring, and who would have been able to carry out multiple pregnancies without injury. ~ American psychologist David Lewis
