The results, which contradict the notion that human beauty is universal, are published in the journal PLOS ONE<\/i><\/strong>. The researchers studied chin shapes among 180 male and female skeletons in nine areas in Australia, Africa, Asia, and Europe to test the universal facial attractiveness hypothesis.<\/p><\/blockquote>\n The hypothesis proposes that some facial features are universally preferred by the opposite sex because they are reliable signals of mate quality<\/strong>. But the researchers found significant geographic differences in the chin shapes.<\/p><\/blockquote>\n The results challenge Darwin’s theory, at least with regard to chin shape, that sexual selection results in the proliferation of physical characteristics that provide a competitive advantage in the struggle to find mates.<\/p><\/blockquote>\n “If preferences for particular chin shapes are universal in the strict sense, and these preferences influence the evolution of the chin, then chin shapes should not differ significantly between geographic regions<\/strong>,” the authors wrote. “But our results suggest that chin shape is geographically variable in both sexes, challenging the notion of universal sexual selection on chin shape.”<\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":" From the Dartmouth College press release via EurekAlert!: There is no single sexy chin.
