How Many People In The World Have Blue Eyes?

How Many People In The World Have Blue Eyes
Blog 1. Only 8 Percent of the World’s Population Has Blue Eyes If you have got blue eyes, you might just belong to one of the world’s most exclusive groups without realising it! Since blue eyes are genetically recessive, only 8 percent of the world’s population has blue eyes.

While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.2.
There is No Blue Pigment in Blue Irises The colour of our eyes depends on how much melanin is present in the iris.
Blue eyes get their colour the same way water and the sky get their blue colour — they scatter light so that more blue light reflects back out.

The iris is made up of two layers. For almost everyone — even people with blue eyes — the back layer (called the pigment epithelium) has brown pigment in it. The front layer of the iris (called the stroma) is made up of overlapping fibers and cells. For people with brown eyes, some of the cells also have brown pigment in them.

If there is no pigment at all in this front layer, the fibers scatter and absorb some of the longer wavelengths of light that come in.
More blue light gets back out and the eyes appear to be blue.3.
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.

Since blue eyes contain less melanin than green, hazel or brown eyes, photophobia is more prevalent in blue eyes compared to darker coloured eyes. For these reasons, having less melanin in your irises means that you need to protect your eyes more from the sun’s UV rays.

Therefore, it is recommended to those with blue eyes to stay out of the sun for long periods of time and try to wear protective eyewear when you are outdoors.4.
All Blue-Eyed People May Have A Common Ancestor Originally we all had brown eyes, however, according to researchers at the University of Copenhagen, it appears that a genetic mutation in a single individual in Europe 6,000 to 10,000 years ago led to the development of blue eyes.

Therefore, we can conclude that this genetic mutation is the cause of eye colour of all blue-eyed humans alive on the planet today. What is the genetic mutation? A genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a “switch”, which “turned off” the ability to produce brown eyes.

The OCA2 gene codes for the ‘P protein’, which is involved in the production of melanin (the pigment that determines the colour of our eyes, skin and hair). The “switch”, does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris – effectively “diluting” brown eyes to blue.

According to Hans Eiberg, associate professor in the Department of Cellular and Molecular Medicine from the University of Copenhagen, “From this, we can conclude that all blue-eyed individuals are linked to the same ancestor. They have all inherited the same switch at exactly the same spot in their DNA.” 5.

Blue Eyes at Birth Doesn’t Mean Blue Eyes For Life While blue eyes may be rare, they’re among the most common eye colours at birth.
Since the human eye does not have its full adult amount of pigment at birth, most Caucasian babies are born with blue eyes.
However, since human melanin tends to develop over time — this causes the child’s eye colour to change as more melanin is produced in the iris during early childhood.6.

People With Blue Eyes May Have a Higher Risk of Alcoholism A new study suggests that individuals with blue eyes are at a higher risk for alcohol dependency compared to those with darker eyes. Therefore, this finding adds further evidence to the idea that alcoholism has a genetic component.

A study published in American Journal of Medical Genetics, Part B: Neuropsychiatric Genetics found that European Americans with blue eyes had up to 83 percent higher odds of becoming dependent on alcohol, compared with matched controls who had darker eye colours. This research suggests that alcoholism has a genetic component linked to genetic sequences that determine eye colour, which may help explain the association.

However, at this stage, the reason for the correlation is still unknown and further research is required to fully understand this correlation in the findings.7. You Can’t Predict the Colour of Your Child’s Eyes Since it was once believed that eye colour — including blue eyes — was a simple genetic trait, many people used to believe that blue-eyed people could only have blue-eyed children.

Before geneticists fully understood how human eye colour inheritance works, a child’s eye colour to used be used as a paternity test — based on the assumption that you could predict a child’s eye colour if you knew the colour of the parents’ eyes and perhaps the colour of the grandparents’ eyes. But geneticists now know that this concept is far more complicated, as eye colour is influenced by an interaction of as many as 16 different genes — not just one or two genes as once thought.

Additionally, the anatomic structure of the iris can also influence eye colour to some degree. In summary, it’s impossible to know for sure if your children will have blue eyes. Even if you and your partner both have blue eyes, that’s no guarantee your child’s eyes will also be blue.

Do blue eyes come from Europe?

1. Everyone with blue eyes is related – Between 6,000 and 10,000 years ago, a baby was born in Europe with a harmless genetic mutation. That little DNA blip was blue eye color, according to researchers at the University of Copenhagen, As far as researchers can tell, this was the first person with blue eyes, and everyone who has blue eyes today is a (very) distant relative of this ancient human.

Originally, we all had brown eyes,” said Hans Eiberg, associate professor in the Department of Cellular and Molecular Medicine at the university.
But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a ‘switch,’ which literally turned off the ability to produce brown eyes.” Eye color depends on how much of a pigment called melanin lives in the iris of the eye.

Melanin is also responsible for the color of our skin, eyes and hair. This genetic switch limits how much melanin is produced in the iris — effectively “diluting” brown eyes to a shade of blue. In addition to having significantly less melanin in their iris than people with brown eyes, hazel eyes or green eyes, blue-eyed individuals don’t have very much variation in the part of their DNA responsible for melanin production.

Do you have blue eyes?
While it’s a very rare type of cancer, people with blue eyes are at higher risk of developing ocular uveal melanoma. Plus, although this cancer is extremely rare, light-eyed folks are also more susceptible to sun damage from exposure to UV rays. So keep in mind, if you want to protect and preserve those baby blues, you need to keep up with routine eye exams. Schedule an appointment with a local eye doctor today!

What race has first blue eyes?

Okay, let me preview this article: I posted this scientific finding about the MUTATION of Brown eyes to being Blue due to a recent post on the subjects in a couple of threads. My parents tell me, out of my siblings that I was born with blue eyes and red hair and red skin.

By the time of my 4th month baby picture, I can see that my eyes were light brown, and my hair and skin was very red.
Not anymore.
My siblings came out brown.
One of my younger siblings was born very chocolate and she was clean bald but later, she grew beautiful and very black hair that does not ‘fro’, but it has a combination texture.

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. Based on my research, I absolutely agree.

Blonde hair and Blue eyes is NOT a White European trait in origin for significant reasons and although the scholars today give partial break down on this subject, it still is scientifically based.
Blue eyes stem from ‘PIGMENTATION’ and without this, eyes will not have any coloring such as in a pure ALBINO.

So this has been obvious to the scientific community for a long time, but for some reason they just are reporting this now. Like Blue eyes, ‘Blonde hair’ also has pigmentation! –But not, White hair. There is a difference between Blonde hair, White hair and Graying hair.

BTW—This would be the same account given in my reference source, scientific reference source, about the Biblical Cain. His descendants migrated NODEAST and that would have been, Northeast of ‘Eden’ where the four rivers began, and thus, around the Black Sea Area were the first ancient city-civilization set up in CATAL HUYUK.

======================================================= How one ancestor helped turn our brown eyes blue Thursday 31 January 2008 01:00 Steve Connor “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.

Preliminary DNA analysis of the exceedingly well-preserved 7,000-year-old skeleton, dubbed Brana-1, has overturned ideas about the descent of modern Europeans. Although the hunter’s closest modern-day relatives live in Sweden and Finland, the genes for his skin colour are African.

Researchers have finally located the mutation that causes blue eyes, and the findings suggest that all blue-eyed humans share a single common ancestor born 6000 to 10,000 years ago.

Researchers have implicated the OCA2 gene in several eye colors.

Are black babies born with blue eyes?

What Color Eyes Are Babies Born With? – The color of babies’ irises actually depends on melanin, a protein secreted by special cells called melanocytes that also give your baby’s skin its color. Babies whose heritage is dark-skinned are usually born with brown eyes, whereas Caucasian newborns tend to be born with blue or gray eyes.

Since melanocytes respond to light, at birth a baby may have eyes that appear gray or blue mostly due to the lack of pigment and because he’s been in a dark womb up until now.
As he’s exposed to more light, over time (even several years) his eye color can change.
If the melanocytes secrete just a little more melanin, this baby may end up with blue eyes.

Just a little more melanin and his eyes will be green or hazel. Brown eyes, which are the most common, are the result of very active melanocytes secreting lots of melanin. Brown eyes are likely to remain brown throughout life. It takes about a year for the melanocytes to finish their job and for the final color to come in.
