Beauty may be in the eye of the beholder, but what’s influencing our eye? Scientists reveal that it’s not genetics but life experiences that lead us to find one face more attractive than another. This finding furthers the on-going debate of nature versus nurture.

Here's how the study went down: Researchers asked 547 pairs of identical twins and 214 pairs of same-gender fraternal twins to view 200 faces and rate them on a scale of one to seven, with one being the least attractive and seven the most attractive. A group of 660 non-twins then completed the same survey. If genes were more involved in facial preference, identical twins would have had similar ratings; if the influence of a familial environment carried more weight, fraternal twins would have also answered similarly. However, most twins’ scores were quite different from one another, suggesting that something else was at play.
