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

Her nose looks like the head of a penis.

Actually, the penis' balls look like Barbra Streisand's boobs.

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

Seems of late, all I see is de-evolution

I believe the reason I wouldn’t defend Angelina Jolie is that hse is too freakish and her recent penchant when it comes to adopting children creeps me out. I’m female, but not so blind that I would defend someone beautiful if they had a revolting personality.

A more scientific look at how drinking beer would help.

The "beer goggle effect", beta, can be quantified as follows:

An = number of units of alcohol consumed
S = smokiness of the room (graded from 0-10, where 0 clear air; 10 extremely smoky)
L = luminance of 'person of interest' (candelas per square metre; typically 1 pitch black; 150 as seen in normal room lighting)
Vo = Snellen visual acuity (6/6 normal; 6/12 just meets driving standard)
d = distance from 'person of interest' (metres; 0.5 to 3 metres)

A value of less than one means virtually no effect. Values of 1000 or more would be needed to even glance in the general direction of Helen Thomas.

She has had her nose 'tweaked' a little...but her lips are the original equipment.

Her mother died very recently from cancer. There was a fairly recent photo of Angelina and her mom...even though her mom had been very ill, you could see the beauty and strong resembelance between the two.

I really do respect the Gates’ for their unaltered appearance. Really...I do. They have all of the money in the world and they could have ‘anything’ done...but they haven’t. So I kind of admire Bill’s $10.00 haircut look...it says ‘I know my hairstyle isn’t important.’

I also have to respect Bill's choice for a life mate. He could have his pick of some of the world's most gorgeous women. Instead, he used a different criteria.

I hope I live long enough to see how their progeny turn out as human beings.

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

That's a pretty long carrot, but if you look around in the produce section you can find longer. Most of the time I buy baby carrots. They go better in roasts and are more tasty.

I like roasted carrots along with pot roast. Tasty.

An interesting observation I have made over the years here in Washington is when I am at the malls and observe the people walking around those at the mall in the affluent city of Bellevue I notice the people tend to be good looking, they dress nice, and the number of extremely overweight people is few and far between. But in Tacoma 20 miles to our south an industrial town with a much lower average income, the people walking around the mall are just plain uglier, they dress trashy and there are allot of extremely overweight people. Kids walking around looking like gangsta-wanta-be’s are also prevalent.

Hurts me to say that too, because I was born in Tacoma. I think there may be something to this peacock theory. Thankfully I married a bellevue girl.

Re post 121, what you wrote makes eminent sense from the viewpoint of women seeking out successful mates who would provide them with economic security. I was just looking at this particular union from the initial post of this thread in which biologists wonder why matings do not produce good-looking progeny and they think that females would seek out attractive males. Well, at least that was my understanding of the initial post.

None that would ever admit to it.....or who likely lived (intact or not insane)to tell the tale.
