The way a baby lies down or sleeps sitting up also has an influence on head shape. Perhaps babies are sleeping in different positions and on different surfaces than they did 9,000 years ago.

People with more refined favial features may be more attractive to the opposite sex and therefore more successful breeders. That's not evolution.

I don't buy everything about evolution personally, but you just gave a text book definition of the theory.

Natural selection changing the genes that get inherited, regardless of cause or motivation, is one of the two key components of evoluation. The other, of course, is genetic change (the source or cause of which is mathematically irrelevant.)

That's the essence of evolution.

Sure it is. EXACTLY "survival of the fittest. In this case the "fittest factor" is "attractiveness to the human female". Also postulated to be why only human females have large "tetas" compared to the rest of the primates.
