Facial Beauty is unique to Humans and supports the accelerated proliferation of Intellectual traits.
We have been evolving our cognitive ability many folds in the past 500,000 years. Such a leap in cognition is unique to our species and unprecedented in the history of earth itself.
Certain higher Primates and Humans have evolved a rather complex ability to recognize faces and highly correlate facial beauty to sexual attractiveness.
Since Facial Beauty neither predicts the sexual potency or the success of inherent traits, I believe it acts as a badge or indicator of something more hidden such as the cognitive capacity.
Advantageous yet hidden traits in males are more likely to be passed on to more aesthetically appealing females, and so better looking females are more likely to choose better genes.
This could be associated with a metaphor of a gift in a package where in every generation the better gift is being slowly sorted into a better a package. Until our standards of beauty are more or less sure that the best package has the best gift, although it may not necessarily be so. But the better package is appealing to most of us.
I am not sure to what extent this proposition is new, or if natural selection proposes this. I am assuming the role of beauty and its evolutionary significance goes beyond just appealing to the opposite sex and this could explains why beauty is such a sort after attribute.
