Study Explains Why We're Not All Beautiful

A new study explains why we aren't all born with Brad Pitt’s perfectly chiseled features or Angelina Jolie’s 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 feathers—the peacock version of George Clooney. These more attractive features usually indicate some other level of genetic fitness, such as disease resistance, that the female’s 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 isn’t the case: for every Johnny Depp out there, there’s a George Costanza—in 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 wouldn’t get evolution,” Petrie told LiveScience.

But a group of British scientists think they have found the answer to the paradox in the human body’s “DNA repair kits.”

DNA repair kits

A cell’s DNA repair kit is not really a kit but a set of molecular processes that routinely repair the damage

I don’t see any sign of evolution in modern man.

How about because people have varying concepts of "beauty?"

What is attractive to one, could be ugly to another (for animals).

Add onto this humans, who hopefully are not so base that all humans marry based on physical appearance.

Because it has less to do with what they are born with, and more to do with their souls shining through the exterior. ;)

This should never be mentioned without referencing Zahavi.

Also, the idea of ‘beautiful’ changes over time and culture. A trip to a portrait gallery will show you that.

My oh my, how educated these dumb people are.

This is easy: once upon a time, God ordained that::

“There shall be an Ass for Every Seat!”

And people have been obedient to that law since time began.

Sheesh

Actually, there are plenty of signs of ongoing evolution in human beings. Two recent studies, for example, showed evidence that human brains have evolved (and are continuing to evolve) new genes within the last 10,000 years.

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.

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.

Shalom.

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.

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.

In some of her earlier work, Petrie showed that men with greater genetic diversity in areas of the genome relating to disease defense were also rated as more attractive by women.

I believe the point of the research is this:

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.

Aw, come now! There aren’t THAT many ugly people!

Everything is Beautiful
Ray Stevens

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...
