People of mixed race are seen as more attractive than non-mixed-race people, a study out of the United Kingdom says.
In the largest study of its kind, Dr. Michael Lewis from Cardiff University collected a random sample of 1,205 black, white, and mixed-race faces. Each face was then rated for their perceived attractiveness to others.
Mixed-race faces, on average, were perceived as more attractive.
Lewis was working on previous smaller scale studies that have also suggested these results.
As well, in 1876, Darwin discussed heterosis, a biological phenomenon that predicts when animals cross-breed, their offspring are genetically fitter than their parents.
Lewis' study was presented at the annual meeting of the British Psychological Society on Wednesday.
"The results appear to confirm that people whose genetic backgrounds are more diverse are, on average, perceived as more attractive than those whose backgrounds are less diverse. This can be taken as evidence for heterosis among human population groups," Lewis said.
"There is evidence, albeit anecdotal, that the impact of heterosis goes beyond just attractiveness. This comes from the observation that, although mixed-race people make up a small proportion of the population, they are over-represented at the top level of a number of meritocratic professions like acting with Halle Berry, Formula 1 racing with Lewis Hamilton; and, o course, politics with (U.S. President) Barack Obama."
