Naturally-occurring blond hair is primarily found in people living in or descended from people who lived in the northern half of Europe, and may have evolved alongside the development of light skin that enables more efficient synthesis of vitamin D, due to northern Europe's lower levels of sunlight.
Finland. Finland has the highest blond hair population by percentage of the total population. Nearly 80% of the population has blond hair, and an astounding 89% of the population has blue eyes. Blond hair and blue eyes are one of the rarest combinations in the world.
Some sources, such as Eupedia, claim that in central parts of Norway, Sweden, Denmark, Iceland and Finland, 80% of the population is blonde, with natural fair-haired people in other Baltic Countries (Latvia, Lithuania, Estonia, and other parts of Scandinavia) making up 50-79% of the population.
Only 2 percent of the world's population has naturally blond hair. If you narrow your sample to white people in the United States, that percentage goes up, but only to 5 percent.
The reason has roots in evolutionary psychology. Both blonde hair and blue eyes are recessive traits, so both parents must carry the gene for blonde hair to pass it on to their kids.
Blonde fact #4: Not all blondes have blue eyes
That's why so many people around the world have black strands and brown eyes. Lighter tint gives rise to lighter coloured eyes, including blue, but also varying tones of green and grey. So, just because you have blonde hair, it doesn't mean that you have blue eyes too.
No, they don't. Blonde hair seems to have appeared more than once in humans. Which means that different blondes trace back their blonde hair to different ancestors. This is actually true of a lot of different traits.
Red- or blonde-haired Vikings? Genetic research has shown that the Vikings in West Scandinavia, and therefore in Denmark, were mostly red-haired. However, in North Scandinavia, in the area around Stockholm, blonde hair was dominant.
Who lived longer, blondes or non-blondes? The researchers showed that the blondes had significantly lower all-cause death. Still, they had a higher mortality from skin cancer. Contrasted and compared to the non-blondes, the blondes had significantly reduced all-cause death.
TIL The rarest natural hair color in the world is red, with only 1-2% of the world population having natural red hair.
Naturally-occurring blond hair is primarily found in people living in or descended from people who lived in the northern half of Europe, and may have evolved alongside the development of light skin that enables more efficient synthesis of vitamin D, due to northern Europe's lower levels of sunlight.
As the population grows and people have babies, the genes for less melanin will become more common. That makes the link between lighter eyes, hair, and skin tighter. So that's why you see people with blond hair typically have blue eyes!
In fact, natural blonde hair can be found within Black communities. For instance, in Melanesia, a subregion of Oceania in the southwestern Pacific Ocean, blonde hair and dark skin is indigenous.
Blond hair and blue eyes are characteristics associated with people from northern European countries such as Norway, Sweden, Finland, Germany, Denmark, etc. These people are said to look "Teutonic" which is a term the ancient Romans gave to a northern European tribe known as the Teutons.
As a result of the relatively low levels of sunlight for most of the year, humans in Scandinavia began to develop symptoms of vitamin D deficiency: namely lighter skin and hair colour. No fellas around? With the sun rarely making an appearance through the Danish winter, it's easy to see how this theory makes sense.
The genes for blue eyes and blonde hair are recessive, meaning both parents must have the genes for them to be expressed in their offspring.
While the study concluded that the average age for a woman to go grey is 33, it found redheads lose their colour at 30, brunettes at 32 and blondes at 35. For one in 10 women, those first grey hairs appear by the time they reach 21-years-old, while one in four women find their first grey by the age of 25.
Does Blonde Hair Make You Look Younger? It does indeed! Warm blonde tones such as honey, gold, caramel and strawberry blonde can take years off your face.
“I always say that going too light can be just as aging as going too dark,” Samra adds. “It's important to maintain a certain level of contrast between your hair color and your skin tone.” Otherwise, your hair loses depth and you'll look washed out.
In mythology, blondes' first appearance was 11,000 years ago with two of the Norse, or Scandinavian, goddesses, Sif and Freyja. Freyja was the goddess of beauty, love, and fertility.
A study found that in the United States 16.6% of the population has blue eyes. The study also found that 28.3% of the population has blonde hair and that 9.3% of the population has blonde hair and blue eyes.
The most important or identifiable haplogroup for Vikings is I1, as well as R1a, R1b, G2, and N. The SNP that defines the I1 haplogroup is M253. A haplogroup is a group of similar haplotypes that share a common ancestor.
So all in all the answer to your question is neither! Blonde hair, brown hair, blue eyes, browns eyes … none of those traits are dominant or recessive, as they are not due to a single gene.
Researchers say it appears blond hair originated in the region because of food shortages 10,000-11,000 years ago. Many men died in long, arduous hunting trips for food, leading to a high ratio of surviving women to men. Lighter hair colors, which started as rare mutations, became popular for breeding, the study said.
It turns out most Vikings weren't as fair-haired and blue-eyed as legend and pop culture have led people to believe. According to a new study on the DNA of over 400 Viking remains, most Vikings had dark hair and dark eyes.
