Extinction of natural blondes?

Question

So, I was reading somewhere (can't quite remember, sorry) that natural blondes are soon to become extinct. The reasoning behind that was when humans started going blonde thousands of years ago it was for procreation. Humans were more attracted to others who had blonde hair, and thus populated the earth. However, with the earth being over populated now, the gene that causes natural blondeness is slowly being weeded out. I think there could be a good theory here, but look at those from Sweden and Norway. Almost 90% of the population there is blonde. What do you all think?

OK, let me set the record straight here. No, I am not blonde, I am a brunette. An intellegent one at that. And the reason why I'm asking is because there's the assumption in society that blondes have more fun and are more attractive. And no, I truly don't believe that blondes are dumb. Hair colour does not indicate intellegence level. And some people's answers here would dictate that. I am simply asking because I am curious what others think. If you don't have a mature, intellegent answer, then move on please.

Answer 1

yea i think that may be a good thing since everyone says that blondes are dumb. that way we have more smart people on the earth. lol just kidding all you so called blondes out there. that is true tho. everyone is a fake blonde. there aren't many true blondes out there.

Answer 2

The gene that creates blonde hair is related to the genes responsible for blue and green eyes, and fair skin. They are all related to a lack of melanin.

People in northern climates developed these genes through natural selection because, in higher latitudes, less sunlight is available to be absorbed by the body. As sunlight provides crucial health benefits, like vitamin D, those with less melanin were able to reproduce more often.

The flip side of this coin is that too much ultraviolet light, which is also provided by sunlight, can be damaging. Prolonged exposure to UV rays can result in sunburns, and in extreme cases cancer.

Of course, technology exists today to protect even the most fair skinned from the results of UV rays, so there are no natural selection pressures against having fair skin even in equatorial regions. So there's no reason to think that this trait will exit the human gene pool, ever.

Answer 3

The issue is just simple genetics Blond haired fairskinned people origionate from colder harsher winter climates. The intermingeling of theese groups with groups from say the mediterranian (greek Italian) the odds of having blond haired offspring decreases.

Answer 4

You may rethink that theory. The blonde gene is just that. It's not like the hair color of a child is going to be a mixture of the hair colors of the parents. If that were the case, we would all end up with the same color hair eventually.

Blond genes are going to be around. I don't think it will disappear.

Answer 5

The gene that causes blond hair is recessive, and as people continue to mate with each other it will slowly be weeded out (as will every other recessive gene). It won't be during any of our lifetimes, though.

Answer 6

I think i should open a hair dye product company. If that theory is correct then more and more blondes would need dyes to keep their unnatural blonde hair.

Answer 7

I always check under the hood just to make sure. It can scar my mind to find out the other.

Answer 8

Pardon my bluntness, but that sounds like a load of crap! Mainly the part about blonde hair existing for procreation.

But it is good for a laugh!

Answer 9

I'm not blonde but are you sure you're not with a question like that. Seriously, thats a pretty dumb thing to say nevermind actually write it down.

Answer 10

i think they are lucky, but na not possible to go out of extinction
