The Melanesian people have a native TYRP1 gene which is partly responsible for the blond hair and melanin, and is totally distinct to that of Caucasians as it doesn’t exist in their genes.
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.
Blond hair has also developed in other populations, although it is usually not as common, and can be found among natives of the Solomon Islands, Vanuatu and Fiji, among the Berbers of North Africa, and among some Asians. In Western culture, blond hair has long been associated with female beauty.
Scientists have shed light on what ancient Europeans looked like. Genetic tests reveal that a hunter-gatherer who lived 7,000 years ago had the unusual combination of dark skin and hair and blue eyes. It has surprised scientists, who thought that the early inhabitants of Europe were fair.
The term ‘ Melanesia ‘ comes from the Greek language, meaning “islands of black [people]” and was used by early European settlers in reference to the dark skin of people in the region, now known as Papua New Guinea, Solomon Islands, Vanuatu and Fiji.
The region includes the four independent countries of Fiji, Vanuatu, the Solomon Islands, and Papua New Guinea. It also includes the French special collectivity of New Caledonia and parts of Indonesia – notably Western New Guinea, which is the Indonesian part of the island of New Guinea.
Between 8 and 10 percent of people worldwide have 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.
Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent. That’s 13 million people, out of the 7.6 billion on Earth. So with numbers this low, could redheads with blue eyes actually go extinct?
Two -thirds of the inhabitants today have green eyes and blonde hair.
About 5–10% of people from Melanesia, a group of islands northeast of Australia, have naturally blonde hair — the highest prevalence outside Europe. Now, a study of people from the Solomon Islands in Melanesia shows that they evolved the striking blonde trait independently of people in Europe.
A Tukey test was applied to this data showing that all three hair colors differed significantly from each other. Brunette was clearly the hair color perceived as most attractive, with blonde as the second most attractive, and red as the least attractive.
New research shows that people with blue eyes have a single, common ancestor. 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.
Black hair is the darkest and most common of all human hair colors globally, due to larger populations with this dominant trait. It is a dominant genetic trait, and it is found in people of all backgrounds and ethnicities. It has large amounts of eumelanin and is more dense than other hair colors.
Estonia. Estonians are known for their fair-haired, blue – eyed appearance with the percentage of people with blue eyes estimated at nearly 90%, though some observational studies have concluded many of these may be more toward blue -grey in color meaning they contain even less melanin than their pure- blue cousins.
Today only about one 1 of every 6 Americans has blue eyes, said Mark Grant, the epidemiologist who conducted the study. Grant was moved to research the subject when he noticed that blue eyes were much more prevalent among his elderly patients in the nursing home where he worked than in the general population.
