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

But we have seen lot’s of ugly folks.

There are sound scientific reasons:

1) Many beautiful people are jerks, and become unbearable before the clothes even come off..

2) There are no ugly people at Closing Time.

2a) Beer.

The reason is simple. Humans like to draw distinctions. No matter what standard of beauty was attainable by humans, say every woman was Nicole Kidman grade, and every man was whatever the equivalent would be, soon we would find that some looked better than others.

It’s just the way we are.

On the bright side, we all look wonderful to out dogs, and also to our cats, at least when the can-opener is running.

That's either stupid journalism or stupid biology. The selective pressures for choosing a man for a mate are different in various places around the world.

US and the civilized world: Attractiveness and money

Africa and Middle East: Can he shoot well enough to protect me? or ideally: Is he from the civilized world?

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.

Well.. uh er.. you see it's like this... Imagine your carrot was 15 inches long.

Well, I knew a guy who was buttfuggly, had no money, and never had a problem dating the hottest chicks.

Oh, THAT guy. Yes, it was a mystery. Every night, he would leave with some gorgeous woman.

"What's his secret?" We asked the bartender.

"I dunno. He just sits there in the corner, by himself, licking his eyebrows..."

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.

So how come we've still got so many Neanderthals who join the DimocRAT party?

Wow, and what did his dates have to say about that?

I've had to tell soooo many women that just because they desire to breed with me, their children are not destined to become an Adonis or a Venus.

It's all in the chips as they fall.

< cough >

This is probably as good of a place as any to ask. Whhat is the big deal about Angelina Jolie?!? I mean, I don't find her ugly, but I most certainly don't find her attractive either. She's an average looking woman for her age. And this is coming from a guy with a soft spot for dark-haired women.

Even more disturbing to me is the reaction of women I bring this up to. These are otherwise perfectly straight chicks who become borderline lesbiotic when you bring up Angelina. "Oh Jeff! She's is SO BEAUTIFUL!!!!!!" I'm sorry. Anna Kournakova is beautiful. Julia Louis Dreyfuss is beautiful. Jolie ain't.

Yup. I've had three wives and four dogs. I still have the dogs. (Click on my name to see their pictures)

yeah, but when they get a chance, they have at it and pop them out by the dozen. LOL.

I can’t get passed Pitt’s smoker nostrils. They’ll only get worse as he gets older, if he continues to puff away.
