Dude, I know you and your penchant for dog fights.
So, I am going to say this just once.
I know that despite your love of needling all and sundry you are an intelligent guy, so am sure you will get this first time round.
There has been much scientific research done on what makes a person beautiful and what does not.
Beauty is created by something known as "dynamic symmetry". All living creatures grow in a ratio called Phi. Every beautiful face fits that ratio...regardless of race. So a beautiful negro or a beautiful Scandinavian face all falls in that ratio. Google Marquardt's mask. This is a geometrical "mask" that aligns perfectly, to the millimeter, against a beautiful face.
The reason why humans are attracted to this particular geometry is that it is the healthiest and is created under optimal conditions. So when a population is well fed nutritionally , not just calories, they tend to produce more babies with dynamic symmetry. This is true of all human beings. When nutrition goes wrong, for instance the mother is a little short of say vitamin A , the fetus eye lens will not be perfectly round but a little oval leading to near sight. The same for other features too. So beauty was an indication to our ancestors as to the health and fertility of future partners.
It is hard for me to explain in just few sentences as there is a lot of scientific ideas involved and I can never be sure if you are just trolling or serious.
