Beauty is an advert for good genes, reports The Daily Telegraph today. It says that “research conducted across cultures and species”, has found that not only are symmetrical faces regarded as being more attractive, but that they also may indicate good genes, health and long life.

The newspaper story is based on research which investigated whether facial symmetry is linked to how feminine or masculine a face is considered to be. However, this research has not investigated or suggested that increased facial symmetry, or “beauty” as the Telegraph describes it, is linked to better genes and that asymmetry is linked to less favourable genes. These are evolutionary theories that have been previously been suggested, mainly in the context of animal mating patterns. The first line of the news article that “beautiful people are healthier and live longer” may or may not be the case, but as this research did not investigate this, it cannot add any evidence either way.
