Through the analysis of ancient DNA, a 2020 study published in Experimental Dermatology suggested that the common gene for blue eye color likely originated in the Near East and arrived in Europe around 42,000 years ago, after the exodus out of Africa.
Blue eyes is a recessive mutation, weather it's in European or in Africa and most likely it originated in Africa.
A couple of years ago, scientist determined that BLUE EYES was a MUTATION that occurred around 6,000 years ago and it stems from A BLACK MALE AFRICAN ORIGIN. They report several archeological proofs puts this event around the BLACK SEA AREA.
The most prevalent place to find people with blue eyes (and where those percentages are considerably higher) is in the Scandinavian region. Europe also has pocket where people with blue eyes can be more commonly found. While the color blue is beautiful in the eyes, it is also evidence of less melanin production.
In 2006, researchers discovered a 7,000 year old body from the Stone Age in the La Brana cave system in Leon in Northern Spain (Image 4). Genetic testing determined that this man had blue eyes. It was not in itself unusual, but what is remarkable is that he is the earliest known person with blue eyes.
"Some ancient Egyptians could have been blue-eyed blondes or brown-eyed blondes," she said. "I wouldn't say ancient Egypt was multi-cultural like Australia today but certainly there were various mixes."
How many eye colors are there, and why your shade is unique to you. At some point, you've probably wondered what the rarest eye color is. The answer is green, according to the American Academy of Ophthalmology (AAO). Only about 2 percent of the world's population sport this shade.
A report from the University of St. Andrews, published this week in Evolution and Human Behavior, says north European women evolved blond hair and blue eyes to make them stand out from their rivals at a time of fierce competition for scarce males, the Sunday Times of London reported.
Black is the dominant allele..!!
Blue Eyes are More Sensitive to Light
Melanin in the iris of the eye appears to help protect the back of the eye from damage caused by UV radiation and high-energy visible “blue” light from sunlight and artificial sources of these rays.
Higher Concentration of Melanin
Most Africans have high levels of melanin that results in yellow eyes. Melanin determines the color of your skin, sclera and eyes. When this concentration increases, the eye color becomes light yellow or muddy brown.
People of Asian, Spanish, South American, and South African descent are most likely to have amber eyes.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
Genetic research indicates that the mutation that caused blue eyes probably occurred between 6,000 and 10,000 years ago with an individual in northern Europe. The mutation essentially “turns off” the iris's ability to produce melanin. Generations and millennia later, the world has millions of people with blue eyes.
Green is the rarest eye color in the world, with only 2% of the world's population (and fewer than one out of ten Americans) sporting green peepers, according to the American Academy of Ophthalmology (AAO).
Flexi Says: Two brown-eyed parents (if both are heterozygous) can have a blue-eyed baby. If both the parents have brown eyes, then there is generally a 25% chance for their child to have blue eyes. Because both the brown-eyed parents have a recessive blue-eye gene and can pass it to the next generation.
Myth: Two blue-eyed parents can't produce a child with brown eyes. Fact: Two blue-eyed parents can have a child with brown eyes, although it's very rare. Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
Eye colour, or more correctly iris colour, is often used as an example for teaching Mendelian genetics, with brown being dominant and blue being recessive.
Some possible ways an African-American person might have ended up with blue eyes are: Caucasian relatives in their ancestry (the most likely reason) A rare disease that causes albinism only in the eyes (ocular albinism) A new mutation that makes their eyes blue.
Recent genetic studies show that the Vikings were a diverse group in terms of genetic makeup and physical traits. They had a variety of hair and eye colors, body types, and other physical characteristics. Yet, evidence suggests that many Vikings did have blue eyes, though certainly not all.
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.
We did a little digging to answer these questions and here's what we found: Her eye color was actually natural — for the most part. Colored contacts weren't commercially available until 1983, so Taylor wasn't faking it. However, she was born with a very specific and rare amount of the pigment melanin.
One thing these survey results have in common is that light-colored eyes — green, gray, blue, and hazel — are named as the most attractive eye colors in the world. In one large survey of more than 66,000 people, green was chosen as the most attractive eye color. Green is also among the rarest eye colors.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich brown eyes.
