  This is Scientific America 60-second science, I'm Sophie Bushvick, got a minute?
  All humans evolve to find certain female traits attractive across cultures because the signal of potential means reproductive potential. Right?
  Actually a new study finds that cultural norms can play a big part, at least when it comes to big feet. Once women give birth their feet tend to grow larger, which means small feet markers for use and fertility and not should be universally attractive. A previous study did find wide spread small foot preference. But University of Washington Anthropologist 1 Jack 2 Coshneck tested the hypothesis again. Among Indonesians called the Carobaltog, 159 men and women looked at a series of famale figures identical except for suddenly different foot sizes . Surprisingly, the Carobaltog rated the images with the largest feet the most attractive. The work is in the journal Human Nature. Among the Carobaltog and other rural societies with lower exposure to media, large feet are sighs of woman strength and ability to do agricultural work. This cultural big foot bias 3 contradicts the notion of universal ideas of beauty. Attractiveness is not one size fits all.
