“The mutations responsible for blue eye colour most likely originate from the north-west part of the Black Sea region, where the great agricultural migration of the northern part of Europe took place in the Neolithic periods about 6,000 to 10,000 years ago,” the researchers report in the journal Human Genetics.
Who is the common ancestor for blue eyes?
A team at the University of Copenhagen have tracked down a genetic mutation which took place 6-10,000 years ago and is the cause of the eye colour of all blue-eyed humans alive on the planet today. “Originally, we all had brown eyes,” said Professor Hans Eiberg from the Department of Cellular and Molecular Medicine.
What ethnicity has blue eyes?
Blue eyes are most common in Europe, especially Scandinavia. People with blue eyes have the same genetic mutation that causes eyes to produce less melanin. The mutation first appeared in a person living in Europe about 10,000 years ago. That individual is a common ancestor of all blue-eyed people today.
Did Vikings have blue eyes?
Turns out they didn’t much resemble Thor or Ragnar Lothbrok.
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.
Is blue eyes a result of inbreeding?
However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.
What is the rarest eye color in the world?
Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer. Eye color isn’t just a superfluous part of your appearance.
How common are blue eyes in the US?
Blue is the second most common eye color globally, with estimates suggesting that 8–10% of people have blue eyes. In the U.S., that proportion is higher, at about 27%.
Do I have GREY eyes?
According to the Eye Doctors of Washington website, gray eyes, unlike blue eyes, often have flecks of gold and brown in them. If you look closely, you may even see gray eyes changing color. Depending on what a person is wearing and what color light they are in, a person’s gray eyes may appear gray, blue, or even green.
Where did blonde hair and blue eyes originate?
Perhaps the most plausible theory is that blonde hair and blue eyes arose because of a mechanism called sex selection. This is where males and females choose as their mates those who have one unusual physical characteristic, not necessarily associated with “fitness” per se but simply something unusual.
What nationality has blue eyes and blonde hair?
Scandinavian regions such as Finland, Sweden and Norway. North Eastern Slavic regions also have the blond hair and blue eyes in their genetics, countries such as Poland, Ukraine, Russia and Belarus.
New research shows that all blue-eyed people share a common ancestor. This person lived more than 6,000 years ago and carried a genetic mutation that has now spread across the world. The exact cause remains to be determined, but scientists do know that eye color began to change long before recorded history began.
What’s special about blue eyes?
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.
Can people with blue eyes see better in the dark?
Blue Eyes. Blue eyes have less melanin compared to brown, but both colors are relatively common throughout the world. … People with blue eyes tend to have greater light sensitivity. Night vision is often better among people with blue eyes.
