Study Explains Why We're Not All Beautiful

A new study explains why we aren't all born with Brad Pitts perfectly chiseled features or Angelina Jolies pouty lips.
A long-standing thorn in the side of biologists has been the difficulty in accounting for the enormous variation between individuals when sexual selection by females for the most attractive mates should quickly spread the best genes through a population.
It is a major problem for evolutionary biology, said study team leader Marion Petrie of Newcastle University.
The lek paradox
For some species, females select the most attractive males to mate with: female peacocks will choose males with the longest tail feathersthe peacock version of George Clooney. These more attractive features usually indicate some other level of genetic fitness, such as disease resistance, that the females offspring will then also inherit.
According to this method of sexual selection, if females only bred with the most attractive males, then all males should be equally attractive and sexual selection could not take place. (In the peacocks case, all males would have similarly long tails.) But clearly this isnt the case: for every Johnny Depp out there, theres a George Costanzain humans, birds and other animals alike.
This so-called lek paradox (a lek is a group of males congregated for mating) has plagued evolutionary biologists for decades.
If you had no variation at all, you wouldnt get evolution, Petrie told LiveScience.
But a group of British scientists think they have found the answer to the paradox in the human bodys DNA repair kits.
DNA repair kits
A cells DNA repair kit is not really a kit but a set of molecular processes that routinely repair the damage

Not nice to post a picture of your GF on this thread, Dig. ;)
Waxman is looking more and more like Yoda every day!
Well! There's your proplem. I think George Costanza is WAY sexier that prissy, scary, Johnny Depp.
It all comes down to individual brain wiring. I tend to select my mates by there testosterone, sweat and agression and not their pampered, soft-handed good looks.
If he has any offspring at all, it’s against all odds.
Dang, that nasty global warming sure did a number on his face.
Ugly people dont get the chance to reproduce as much........
“Then why are there so damned many of them?
Because they find each other.”
No, they find BEER!!!!!!!
Well that study doesn’t apply to me, so I’ll skip this thread.
We don’t all drink beer all day.
That would fix it...:)
The answer is easy.
We think we know why animals pick a mate.
But we really don’t.
We just think we do.
That’s probably the case for much of biology.
Doing my part for population control.
Of course, that depends on what 'ugly' is. To many women, a guy not having a lot of money is 'ugly'. Some may even substitute the money for power/ influence/ intelligence.
