Which concept addresses the evolutionary basis for attractiveness towards symmetrical faces?

The concept that specifically addresses the evolutionary basis for attractiveness towards symmetrical faces is indeed best captured by the facial symmetry hypothesis. This hypothesis posits that symmetrical faces are perceived as more attractive because symmetry is often associated with genetic health and fitness in evolutionary terms. Individuals who exhibit symmetrical features may be considered more appealing as potential mates since such traits suggest robustness and vitality, advantageous for reproduction.

The other concepts mentioned do not fully encapsulate this evolutionary perspective. Aesthetic symmetry theory focuses on the artistic elements of symmetry rather than its biological implications. The perceptual bias view relates to how our cognitive processes can influence our preferences but does not specifically tie these preferences to evolutionary advantages associated with symmetrical faces. Biological attractiveness theory may encompass a broader understanding of attractiveness but does not specifically hone in on the link between facial symmetry and evolutionary benefits.
