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

Well, I knew a guy who was buttfuggly, had no money, and never had a problem dating the hottest chicks.
Years later we found out that he was the proud owner of fifteener.
And there were witnesses.
Bodies better at killing bacteria smell better.
Beautiful people are more likely to possess/carry genetic (DNA) mutations. Nature wants these subtle mutations, so it makes the carriers more attractive and more likely to mate more often.
She has always had those lips....
Looks like Al’s been playing in Kerry’s makeup kit again.
Aw, come now! There aren’t THAT many ugly people!
Everything is Beautiful

Jesus loves the little children,
All the little children of the world.
Red and yellow, black and white,
They are precious in his sight.
Jesus loves the little children of the world.
Everything is beautiful in its own way.
Like the starry summer night, or a snow-covered winter’s day.
And everybody’s beautiful in their own way.
Under God’s heaven, the world’s gonna find the way.
There is none so blind as he who will not see.
We must not close our minds; we must let our thoughts be free.
For every hour that passes by, we know the world gets a little bit older.
It’s time to realize that beauty lies in the eyes of the beholder.
And everything is beautiful in its own way.
Like the starry summer night, or a snow-covered winter’s day.
Oh, sing it children!
Everybody’s beautiful in their own way.
Under God’s heaven, the world’s gonna find the way.
We shouldn’t care about the length of his hair, or the color of his skin.
Don’t worry about what shows from without, but the love that lives within.
And we’re gonna get it all together now; everything gonna work out fine.
Just take a little time to look on the good side my friend,
And straighten it out in your mind.
And everything is beautiful in its own way.
Like the starry summer night, or a snow-covered winter’s day.
Ah, sing it children!
Everybody’s beautiful in their own way,
Under God’s heaven the world’s gonna find a way.
One more time!
Everything is beautiful in its own way.
Like the starry summer night, or a snow-covered winter’s day...
What?
HA!
Mebbe...
But that nose has had some work.
Here's more antidote, lol!
I am not sure what to make of the genetic way forward for Bill and Melinda.
Thanks for posting photo. I know Angelina is the real deal (at least as to poutly lips).
Before I proceed any further, and you may think I’m ignorant, but I have to admit I have no idea what a fifteener is.
As for a guy having no looks, no money, and no brains, well, women form the other half of natural selection. Who’s to say they can’t make mistakes? Lol!
That’s one of the best posts I’ve seen...LOL
Beauty may be skin-deep, but ugly is to the bone...
