Scientists concluded that every blue-eyed person on the world today can trace their ancestry back to a single European who probably lived about 10,000 years ago in the Black Sea region and who first developed a specific mutation that accounts for the now widespread iris coloration.
Majority of Russians have brown eyes, say 70% of the total population. But in Western Russia, the area close to Moscow and St. Petersburg the general colour could be gray or bluish. Swedes have the same eye colour as Russians have.
It's a common belief that all babies are born with blue eyes, but this is actually a myth. A baby's eye colour at birth depends on genetics. Brown is also common, for example, but a newborn baby's eyes can range in colour from slate grey to black.
Blue Eyes. Originally, all humans had brown eyes. Some 6,000 to 10,000 years ago, a genetic mutation affecting one gene turned off the ability to produce enough melanin to color eyes brown causing blue eyes.
Blue is the second most common eye color globally, with an estimated 8 to 10 % of people having blue eyes. A majority of these people are of European descent, however, Black people can be born with blue eyes even though it's pretty rare.
So where did our green-eyed ancestors come from? Most origins point to areas around the Caucasus Mountains, which link Asia and Europe. That may help explain why so many different countries and continents have had green-eyed populations for thousands of years.
“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….
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.
"Don't only Caucasians have blue eyes?" No. From your wikipedia link: Blue eyes contain low amounts of melanin... Blue eyes are most common in Northern Europe and Central Europe and to a lesser degree in Southern Europe,North America and southern Central Asia; Afghanistan is a notable example.
While the blue is the most popular colour these cats do come in white and black as well, though the black and white cats are very rare. If you are thinking of buying a Russian Blue it's best to find a reputable breeder so that you can be sure you are getting a pedigree.
The Slavs are Europeans with the hair and eye colors of Northern Europeans. It is common for Slavs to have dark hair and dark eyes, but contrary to both the Nazi and Cold War stereotypes, it is also common for Slavs to have light-colored eyes and blond hair.
Black Russian Color Composition
The color Black Russian belongs to the color family Dark Purple. It is of low brightness and high saturation. The color Black Russian corresponds to the hex code #0A001C. In the additive (digital) color space RGB (Red, Green, Blue), it corresponds to 4% Red, 0% Green, and 11% Blue.
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.
Italians have all different eye colors including brown, hazel, green, and blue. There are blonde, brunette, and red-haired Italians. The more North you move in Italy the more frequently you will see Italians with blue eyes.
There have been 16 genes identified that contribute to eye colour. This means that no matter what colour eyes your parents have, yours can be pretty much any colour. All races, including Caucasian, African, Asian, Pacific Islanders, Arabic, Hispanic and the Indigenous Peoples of the Americas can have green eyes.
The genetic switch is located in the gene adjacent to OCA2 and rather than completely turning off the gene, the switch limits its action, which reduces the production of melanin in the iris. In effect, the turned-down switch diluted brown eyes to blue.
Your children inherit their eye colors from you and your partner. It's a combination of mom and dad's eye colors – generally, the color is determined by this mix and whether the genes are dominant or recessive. Every child carries two copies of every gene – one comes from mom, and the other comes from dad.
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.
Finland – 89%
Sharing the rank of first in the world with Estonia, Finland also has a whopping 89 percent of its population with blue eyes. The stunning combination of blue eyes and sandy brown or blonde hair is much sought after in other countries, but very much the norm here.
Some ancient peoples in Spain 7,000 years ago had blue eyes and dark skin. Apologies to Frank Sinatra, but the real Ol' Blue Eyes has been found—a 7,000-year-old Spaniard whose fossil genes reveal that early Europeans sported blue eyes and dark skin.
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 found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
Anyone can be born with hazel eyes, but it's most common in people of Brazilian, Middle Eastern, North African, or Spanish descent. When eyes are hazel, they are brown mixed with amber and green. In some cases, there are shades of gray, blue, and gold within the iris too. Brown eyes may also have some green in them.
