Facial symmetry is one specific measure of bodily asymmetry. Along with traits such as averageness and youthfulness it influences judgements of aesthetic traits of physical attractiveness and beauty. For instance, in mate selection, people have been shown to have a preference of symmetry. This is due to the fact that it is seen an indicator of health and genetic fitness, but also as holding adaptation qualities; reflecting the ability to withstand the changes in their environments.
