why blue-eyed guys unconciously prefer blue-eyed girls...

[Dancing Mustard]

I am informed that 10% of Scottish people are redheads of one description or another. Coincidentally this is the highest rate of redheadedness in the world, followed closely by Ireland, with a rate of 7-9% depending on the region.

Anyone else's eyes change between green and brown, and certain shades of blue?

My daughter's do. They are never completely blue, though they were until she was a year old. They are never completely brown, but sometimes they are completely green.

(Did I spell completely correctly?)

yes you did, there's no 'e' between the 'l' and the 'y'

This thread should be renamed "Why blue-eyed girls prefer my cock."

[apey]

You wish

[brooksieb]

this thread shud be named why hitler fancies blue eyed girls....

[suggs]

this thread shud be named why hitler fancies blue eyed girls....

At the risk of being hounded out with cries of "You ponce", Hitler was a curiously asexual man. He wasnt that fussed by woman, or men. No illegitmate offspring.
He did, however, like land. Lots of land.

Why must everything anyone ever says remind me of a Monty Python skit...

[brooksieb]

so what ur saying is hitler is a virgin? how dare you, hitler still deals me stuff till this day!

[0ojakeo0]

You know, if you provided a link as evidence, I might actually believe this.

since blue is a recesive trait i think it must be true but im not sure. we learned it like a month ago and thats a long time

[Neoteny]

If I remember correctly, eye color is particularly complicated and not fully understood. In short, it's not a simple Mendelian dominant/recessive trait.

ALL BLUE-eyed people can be traced back to one ancestor who lived near the Black Sea 10,000 years ago.

Human beings had brown eyes until a single mutation in a gene called OCA2 arose by chance in one individual, Professor Hans Eiberg from the University of Copenhagen said.

The mutation "turned off" the mechanism that produces brown melanin pigment and "diluted" brown eyes to blue.

Most likely occurring in the north-west part of the Black Sea between 6000 and 10,000 years ago, the gene was dispersed in the rapid waves of migration to northern Europe that followed the end of the last ice age.

Professor Eiberg said the finding, published in the journal Human Genetics, helped to explain why Europeans were far more likely to have blue eyes than any other ethnic grouping.

Europeans also had a far greater range of skin tones and hair colours living in the one community than the rest of the world, where people are almost uniformly dark-haired and dark-eyed.

The researchers examined mitochondrial DNA and compared the eye colour of blue-eyed people in countries as diverse as Jordan, Denmark and Turkey.

Variation in the eye colour from brown to green can all be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes.

"They have all inherited the same switch at exactly the same spot in their DNA," the professor said.

"From this we can conclude that all blue-eyed individuals are linked to the same ancestor."

Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production.

Film stars such as "old blue eyes" Frank Sinatra, Nicole Kidman, Paul Newman, Cameron Diaz, Cate Blanchett and Daniel Craig are famed for their dazzling blue eyes, while scientists Marie Curie and Stephen Hawking also shared the prized trait.

The mutation of brown to blue was neither a positive nor a negative mutation, Professor Eiberg said.

It is one of several mutations such as hair colour, freckles and beauty spots, which do not affect chances of survival. "It simply shows that nature is constantly shuffling the human genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so."

[Neutrino]

I don't know why that professor said every blue eyed person is descended from a blue-eyed person. If the mutation can occur once, then it can occur multiple times. There would have been multiple "original" blue eyed people, each starting their own genetically unique chains of blue eyed mutants.

Eh, that's a matter of probability. It's possible there were multiple origins, but I think it's more likely there was only one, particularly as complex as eye color interactions are.

[Neutrino]

I find it difficult to believe that the genes from a single blue eyed person managed to survive and prosper. In all probability, the blue eyed mutation should have been subsumed by the brown-eyed whole, never to be seen again except in genetic throwbacks.*

As far as I know, blue eyes don't confer any evolutionary disadvantages in non-equatorial regions. If natural selection isn't acting on it, sexual selection can work wonders on a phenotype, particularly on arbitrary characteristics. I don't think it's impossible that it occurred on multiple occasions, I just find it unlikely. I wonder, have any time periods for the mutation have been proposed? Comparisons of when the genes branched? I'm not really sure that there has been enough time for the mutation to occur too many times...

I wasn't saying that the blue-eyed gene would be eliminated, just diluted out of existence. The children of this blue-eyed person would presumably have a 50/50 chance of being blue/brown eyed. Since there are no other blue-eyes to mate with, their children will again run the 50/50 roulette...

Bah, I just realised my train of thought was wrong. Only the brown-eyed children will have the blue-eyed gene diluted out of existence. Assuming equal probability, the local blue-eyed population will grow.

Must think my theory through completely before expressing it.

so what if it was made by a gypsie, oh oh... hitler will be very upset...

[bryguy]

because if any of their kids don't have blue eyes then he knows he's not the father

all children of a guy and girl who both have blue eyes must also have blue eyes

so if you don't have blue eyes and both your parents do, the person you think is your father is not your father

uh actually thats not true.

Say that you great great great grandfather had brown eyes, and your great great great grandmother had blue eyes, than most likely their kids will have blue eyes. But the brown eyes gene is still there, so it could be passed down to your great great grandmother, then great grandfather, then grandfather, then dad, and then you could have brown eyes.

basically what the Professor found was that people with blue eyes are mutants.

blue-eyed guys have evolved to subconciously prefer blue-eyed girls for this reason

interesting eh bro

scienceofficergeoff

What a load of bullocks. I prefer any eye-coloured girls because eye colour doesn't matter.

My mom - part native american with brown eyes brown hair - adopted.
My dad - Irish or Scottish with blue eyes and very dark brown hair - red hair in his mother.

1. Me - actual blonde hair and hazel/green eyes.
2. my sister - To the best of my memory, she has light brown hair with maybe a touch of red (she dyes alot). She has brown eyes.
3. My brother has hazel blue eyes and dirty blonde hair.

My kids:
1. Noah hazel green eyes, dark blond hair. his dad has dark blond hair and blue eyes.
2. Wes has blonde hair and hazel blue eyes. dad has strawberry blond hair and blue eyes.

Oh, and me and my siblings and children are pasty white folk, but we tan like you wouldn't believe. I think we get that from my mom.

i have gorgeous blue eyes and dont unconsciously prefer women with blue eyes.

I prefer women that are sterile

Really, women with the incapability of producing tiny, writhing, noisy humans are my preference too. Babies are so friggin weird...
