Blue eyes occur naturally in African people Interestingly, geneticists reported in 2008 that all blue-eyed people can trace this trait back to one single ancestor who lived between 8,000 and 10,000 years ago in the north-west regions of the Black Sea.
“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….
Green Eyes
There is an ongoing debate, wherein a group of people consider green to be the rarest colour while others say it has been dethroned by violet, red and grey eyes. Some of the factors responsible for causing green eyes include a lot of lipochromes, little melanin and the Rayleigh scattering of light.
Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. Most people with blue eyes are of European descent.
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.
"Behind Blue Eyes" originated after a Who concert in Denver on 9 June 1970. Following the performance, Townshend became tempted by a female groupie, but he instead went back to his room alone, possibly as a result of the teachings of his spiritual leader, Meher Baba.
The Vikings had various eye colors, although the predominant eye color was blue or gray. However, Irish Vikings had predominantly brown or hazel eyes, and some Viking settlements were much more diverse than others.
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.
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.
What is the rarest eye color? 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).
What is the most common eye color in Russia? The most common eye color in Russia is brown. It is estimated that around 80% of the Russian population has brown eyes.
Can someone have brown hair and blue eyes? Yes. Hair color and eye color are different genes, so any combination is possible. Brown hair and blue eyes is extremely common in the Western European countries such as Norway, Sweden, Germany, England, Ireland, Scotland, and Wales.
In broad terms Ukrainians are of the Caucasoid or Europoid race, with a wide range of skin color, from pale alabaster white to shades of brown. Eyes vary from the northern light blue to the dark brown to black of the Mediterranean inhabitants.
Hazel eyes have also been voted as one of the most attractive eye colours and can, therefore, be argued to have the best of both worlds, health and beauty. Green eyes are incredibly rare, which may be the reason as to why some believe this to be the most attractive eye colour.
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.
African-Americans with blue eyes are not unheard of, but they are pretty rare. There are lots of ways for this to happen. Some possible ways an African-American person might have ended up with blue eyes are: Caucasian relatives in their ancestry (the most likely reason)
Eagles are thought to have the best eyesight of all; their eyes are as many as eight times sharper than ours.
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.
In fact, in Ireland and Scotland, more than three-fourths of the population has blue or green eyes – 86 percent! Many factors go into having green eyes. Sixteen separate genes have been identified as contributing to eye color.
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.
Both parents have to pass along the blue eye gene in order for their child to have blue eyes. That doesn't necessarily mean that the parents themselves have to have blue eyes; it's possible they carry the gene, but it is recessive. However, a blue-eyed child is almost certain if both parents have blue eyes.
