Today my friend said something interesting...

My friend, an engineering student, was telling me the reason he despised the existence of plastic surgeons.

According to him, plastic surgeons are not doing the world a favour. People who sought plastic surgery are usually people who are relatively less good looking. Going through plastic surgery would help better their looks, if the surgery is successful. He said that, this would mean less good looking people would be naturally selected and their not-so-good-looking genes would be passed on. Human would be, in ugly words, uglier.

(of course, he was just joking, but he has a point)

I came to two conclusions: - 

1) If looks were such a determinant in the process of natural selection, bad looking people would long have been extinct. Facial features contribute to looks and they are what's being passed down. What we are left with are then people who have acceptable and 'good' facial features, since 'bad' features would be extinct.
In other words, everyone is somewhat, already 'good' looking, (because the combination of 'good' facial features will also determine who is even better looking)

If everyone was already 'good' looking, then why need plastic surgeons? People must be unsatisfied with their looks, and have already forgotten that they already have a certain degree of 'good' look, even if they are relatively less good looking.

2) It could be that looks were never a determinant for natural selection in the first place.

1) or 2)? What do you think?
