Some simple and elegant body shapes may however not necessarily be a result of aesthetic selection, but result of optimizing e.g. for resources efficiency or resilience, but this in turn could have initiated feedback loops in sexual selection. Attraction to sexually dimorphic beauty also increases fitness because seeking out the opposite sex is conductive for reproduction. | Some simple and elegant body shapes may however not necessarily be a result of aesthetic selection, but result of optimizing e.g. for resources efficiency or resilience, but this in turn could have initiated feedback loops in sexual selection.

Sexual dimorphism exists in all races, but it is highest in Europeans and Inuits and lowest in Africans. Low dimorphism in Africans has been proposed to be explained by a fast/die young ecology (fast LH) favoring men who impregnate many women, hence the women are more likely left alone and hence need to exhibit male characteristics like physical dominance and dependability.{{citation needed}} | Sexual dimorphism exists in all races, but it is highest in Europeans and Inuits and lowest in Africans.
