Men who think they like big bottoms may actually be more into spines. Men may be directing their attention to the butt and obtaining information about women’s spines, even if they are unaware that that is what their minds are doing.
Men have found spines of this specific degree of curvature attractive for centuries due to the effect it had on a woman’s ability to find food and bear children.
Dr. Lewis said that a 45-degree curve allowed women to search for food later into their pregnancies and continue to have children without injuring their backs.
Women without these curved spines would barely be able to move while pregnant, he added, as a spine without such a curve increases the pressure on their hips by almost 800 percent.
The evolutionary benefits of women with these bodies therefore became ingrained into the minds of men.
