Is naturally blonde hair going to become extinct?

This question assumes that humans are going to continue being controlled by natural selection, as we have been for all of our history.  We are at most a generation away from being able to control simple genetic features, and likely not more than 100 years from controlling more complex genetic features.  Hair color, etc, will be genetically controllable by us long before it would disappear.

Yes.\nBut some - no, make that a lot of - scientists are working on aging, and some believe that if you can eliminate aging, then the natural lifespan of a human will be on the order of 1500-2000 years.\n*Then* we run into some major, new social problems (read John Wyndham's 'Trouble with Lichen' for a slightly dated but still unsurpassed exploration of some of the issues), but I imagine they're not insurmountable.\nNew Scientist ran an article on this in January (link below.) If you want it free you can download it in podcast form. It's pretty neat.

not yet....is she a real blonde?

If there is a selective pressure to do so, then perhaps, given enough generations, this will occur. I consider this pretty unlikely. Even if it did happen, evolution is a slow process, and it would take, at the least, tens of thousands or even millions of years.\n\nMore likely, in the next few centuries, someone will genetically engineer pets to do such.\n\nOh, and it's organisms, not organizisms.

Of course it won't be the same.\n\nBob Barker is a legend. Without him the animal population will be out of control. \n\nBob Barker will be missed. Did he die? Oh how sad !!

Yes. \n\nBlonde hair is a recessive gene, linked to a number of chromosomes. For simplicity's sake, assume it's just linked to one pair. The fact that it's recessive means that if only one chromosome out of the pair is blonde (and the other is brown), the person will have brown hair. Each person then contributes one chromosome out of that pair to their children. So two people with brown hair whose chromosomes are Blonde-Brown could have a child with blonde hair (if they both give the Blonde gene).\n\nSince you have naturally blonde hair, your chromosomes are Blonde-Blonde, so the child's hair color will depend entirely on your husband - that's why someone said the odds are 50%. In fact, multiple genes determine hair color, so that isn't quite correct, but you get the idea.

No, according to some theory my sister told me after she watched the documentary, the male population will decrease over time and become extinct over thousands of years. Then, the female population will dominate the world. How would they reproduce? You would ask. Believe it or not, the females will develop male genitalia (gross) on their bodies as they evolve so that they can self-reproduce and give birth to more baby females. So, in the future, it is possible that there will be only one gender which is female and the evidence shown today is found in certain iguana species that there is only females that self-reproduce. I hope this helps with your question.

One vote for staying bald. Natural is better.

Not sure on that one.  Evolutionists say man must continue to evolve as we have over the years.  And when the secret of the 'aging' gene is discovered, maybe natural death will be a thing of the past, who knows...\n\nBut I don't subscribe to any of that.

Do you mean in humans? Loss of biological diversity in humans is caused in part by genetic drift. Genetic drift is a random loss of genetic material, particularly in smaller populations. Genetic drift doesn't seem to occur in larger populations because there's no selective mating, and alleles are getting thrown around all the time. I heard somewhere that within the next 200 years or so, blondes will disappear because it is a recessive allele. I think that's bull considering the large amount of people with blonde hair, and heterozygous brunettes, but no matter.\n\nThe effect of loss of biological diversity... well I guess that depends. In selective breeding of dogs, breeders notice that they can get good results within the first few generations. For example, if they want really big dobermans, they'll mate two big dobermans, and then mate their largest offspring with other large dogs. After several generations, they'll notice that they can't make the dogs any larger because there's no more variation in size. Because they've been artificially selected, the "big" genes are all that's left, and there's no chance for "bigger" genes because there's no gene flow. (Gene flow is just the introduction of new genes into a population)\n\nI hope that helped, it was a little messy and abbreviated because the concept is very complex.

I have to wonder about your fascination w/ Pandas? Maybe its their simplicity, the black and white color, the robust form, or its innocent relaxing attitude. When Pandas are extinct I know you will miss them but it wont happen in your lifetime. China will miss their #1 mascot and will have to find another one.  Mankind will add another beautiful animal to our list of casualties and greed. Children will learn about them in textbooks the way we do about do do birds and wonder why and what they looked like in real life. On the day the last one dies I believe many people will be ashamed knowing they all contributed in some way to their demise

I am blonde and no one has ever said or implied that I am stupid. I think the media has protraid blondes a air heads. On that Seventie's Show it is a guy who is the air head. It is all just a myth. Brunette's can be air heads too..lol.

I think this is a hoax, my friend.  I know of no honest medical treatment that has the ability to change hair colour.  Or else, it'd be all over the place and no one would have grey hair that didn't want it.\n\nGrey looks distiguished.  Revel in it.

No, it is not yet extinct.\nAs a subject it is more difficult to photograph, etc. than other whale species.\nIt "sounds" or dives to great depths compared to some of the other types.\nI'm not sure of this, but perhaps, it's less sociable than smaller whale species.

whose dumber a natural blond or a dyed blond? \nI'd say a wannabe, he'll give up being a hippie and then fallow a new trend like a blind idiot.

I heard that, and I heard the same thing about Blue eyes.  Most reputable sources say it is wrong, but it seems to make sense to me.  Blonde hair and blue eyes are recessive traits and you'd think the dominant traits would eventually take over in the human race.  That's evolution, right? But who knows.  Science has been wrong before.

No, definitely not. So if you've found hair in an anchovies can or something like that, it came from a mammal. Yeugh.
