Blond hair gene doesn't come from white ppl

The inhabitants of the Solomon Islands - east of Papua New Guinea - are very dark-skinned - but have puzzled scientists for decades with their blond hair.
Now a genetic study has found that the islanders have a 'homegrown' gene that gives them blond hair - and it's different from the one in Europeans.
‘Its frequency is between 5 and 10 percent across the Solomon Islands, which is about the same as where I'm from,’ said study author Eimear Kenny, PhD, who was born in Ireland.

Globally, blond hair is rare, occurring with substantial frequency only in northern Europe and in Oceania, which includes the Solomon Islands and its neighbors.

Many assumed the blond hair of Melanesia was the result of gene flow — a trait passed on by European explorers, traders and others who visited in the preceding centuries.

The islanders themselves give several possible explanations for its presence - they generally chalked it up to sun exposure, or a diet rich in fish, say the researchers.

‘Within a week we had our initial result. It was such a striking signal pointing to a single gene — a result you could hang your hat on. That rarely happens in science,’ said Kenny‘It was one of the best experiences of my career.’

In terms of genetic studies, the analysis was straightforward, said Kenny.

But gathering the data, accomplished in 2009 by Myles and co-first author Nicholas Timpson, PhD, was more difficult. Much of the Solomon Islands is undeveloped, without roads, electricity or telephones.

It's also one of the most linguistically diverse nations in the world, with dozens of languages spoken.


Myles and Timpson went village to village explaining what they wanted to do and asking for permission to gather data, Myles speaking in Solomon Islands pidgin, the most widely understood language.

When the local chief gave the OK, the researchers recruited participants and assessed hair and skin color using a light reflectance meter, took blood pressure readings and measured heights and weights.

They asked the villagers to spit into small tubes to provide saliva to be used for DNA extraction. In the span of a month they collected more than 1,000 samples.

Soon after, Kenny joined the lab and started the analysis, selecting 43 blond- and 42 dark-haired Solomon Islanders from the opposite 10 percent extremes of the hair pigmentation range.

She used these in a genome-wide association study, a method to reveal differences in the frequency of genetic variants between two groups, that usually requires thousands of samples.

Because the vast majority of human physical characteristics analyzed to date have many genetic and environmental factors, Kenny expected an inconclusive result that would require much further study. Instead, she immediately saw a single strong signal on chromosome 9, which accounted for 50 percent of the variance in the Solomon Islanders' hair color.

The team went on to identify the gene responsible, TYRP1, which encodes tyrosinase-related protein 1, an enzyme previously recognized as influencing pigmentation in mice and humans. Further research revealed that the particular variant responsible for blond hair in the Solomon Islands is absent in the genomes of Europeans.

‘So the human characteristic of blond hair arose independently in equatorial Oceania. That's quite unexpected and fascinating,’ Kenny said.

kewl
it will be interesting if they can answer my question about blue eyes

U waiting to hear what ppl think of regular and modified blacks having blond hair? :kicks
That has nothing to do with this said finding.


The fact still remains New World blacks different from Africans because of their admixtures.


We don't look different because of independent mutations that took place within the last several centuries. We look different because of genetic drift that took place in our populations.

Not similar to this finding

What was question about? If its from mixing?
well not even that where did it come from cos originally there was only brown eyes no matter your race. so if it is a result of a mutation what race was that original ancestor that passed on the mutant gene http://www.islandmix.com/backchat/f6/blue-eyes-origin-173004/index2.html

plus if there was a mutation once why couldn't it happen again even within the regla black ppl population. It would be funny again if another feature ppl hold up as the epitome of attractiveness originated from a ppl who've been told they're on the lower end of the attractiveness scale.

have any info on the lore surrounding the haryans?
read once how hitlah went to I think hafghangistan and found some of his long lost people
studied their language and genetics if I am correct and found common ancestry
say all that to say, the blonde hair blue eye to many throughout history has been the look/description of many "gods"
if/when you get a chance see what you can tell me bout that
on the canspiratorial side of things its said they came from the moon

Ignorance pon ignorance! Most "New World blacks do not look that different from West and Central Africans. If fact, you can pinpoint which part of Africa black Americans (North, Central, South) originated based on our features. Even "mixed" Blacks can't hide.
many Jamaicans (and Guyanese) have Senegambian features. Others clearly have bantu or more Sudanic appearances. just a couple of examples below..

Who wouldn't know that the blond hair genes (like all genes ) come from Africa.

Dumb Dumb, nobody said there weren't exceptions. The point still remains: The typical NWB does not resemble a typical Sub Saharan African. Genetic analysis shows that most if not all Aframs have admixture. Take a trip to Harlem and take a look at how folks look. Then take a trip to Nairobi or any major city in West Africa. You would see the stark difference.

People are idiots if they think that European, Native American blood etc. had no effect on their makeup. That blood didn't just disappear people.
