I mean to say why would we preger someone who is aesthetically pleasing? I doesn't seem to have any evolutionary advantage.I'm not sure I understand your question.
Try thinking about birds, instead of humans. Male peacocks have big ornate tails. What is the evolutionary advantage? The females (called "peahens") are somehow predisposed to notice the males displaying big ornate tails and be interested by it. Probably it is hard-wired in their brains.I mean to say why would we prefer someone who is aesthetically pleasing? I doesn't seem to have any evolutionary advantage...
The title of this thread is self defining. If there is a mate selection based on looks, the ones most preferable are "good looking". Mate selection is a way to guarantee healthy genes by competition, where the outcome can be (and often seem to be) more or less random.

Variation is a store of alleles for selection to use to advantage, so an increase is good. But a decrease is also a result of selection. You want a balance, where a modicum of selection can keep up with the environment by having a modicum of variation to chose from.Like if I am attracted to everyone, then I will end up passing on just *my* genes but if everyone mates with different kind of people, then there will be variation. It maybe advantageous to the species.
I assume that "element of accident" refers to contingency, random constraint and/or outcome, since it fits the subject.I don't understand this part.
