The percentage of redheads in Ireland hovers around the 10% mark. Scotland weighs in at around 6%, followed by England at around 4%. Scottish people may disagree, but we say Ireland is the undisputed world capital of redheads.
Ireland has the highest per capita percentage of redheads in the world -- anywhere from 10 to 30 percent, according to Eupedia, a website that explores European genetics and ancestry. They are almost equally prevalent in Scotland and other pockets of Celtic pride.
It is believed there are so many redheads in Ireland, Scotland, and Scandinavia because our redhead ancestors migrated to cooler climates. As you know, redheads have more sensitive skin that burns easily, so a cooler climate was a more comfortable place for our ancestors to live many thousands of years ago.
Ireland has the highest number of red-haired people per capita in the world, with the percentage of those with red hair at around 10%. Great Britain also has a high percentage of people with red hair.
Question: What's the real reason why Scotland is home to so many redheads? Globally, less than 2% of people have red hair—however in Scotland, the portion of redheads falls somewhere between 6 to 13%.
This evolutionary story is believed to be where the Celtic and Viking people got their famously fiery locks from. Today, Ireland and Scotland are both synonymous with red-haired people.
These red hair variants in MC1R likely first appeared in ancient humans around 30,000-80,000 years ago, at about the same time as early migrations out of Africa. Scientists used to think red hair evolved to help people produce Vitamin D in chilly places with little sunlight (think Ireland).
Contrary to what many people assume, redheads did not originate in Scandinavia, Scotland or Ireland, but in central Asia. Their coloring is due to a mutation in the MC1R gene that fails to produce sun-protective, skin-darkening eumelanin and instead causes pale skin, freckles and red hair.
Red- or blonde-haired Vikings? Genetic research has shown that the Vikings in West Scandinavia, and therefore in Denmark, were mostly red-haired. However, in North Scandinavia, in the area around Stockholm, blonde hair was dominant.
Irish people developed their red hair because of a lack of sunlight, according to new research from a leading DNA lab. Irelands DNA has revealed that one in 10 Irish people have red hair but it is thought that up to half the population could be carrying the redhead gene even though they are blonde or brunette.
Most (natural) redheads will have brown eyes, followed by hazel or green shades.
One of the many facts about redheads is that their hair will never turn grey. The pigment in their hair that causes it to be red will just fade over time, causing their hair to turn blonde or white, but never grey.
According to Health Magazine, redheads can produce their own vitamin D when exposed to low levels of light. 4. You may not need as much pain medication. The gene responsible for red hair (MC1R) also releases a hormone that is similar to endorphins which limit the feeling of pain.
"Go gingers," he added. It's a little-known fact that all three of Princess Diana's siblings — Lady Jane Fellowes, Lady Sarah McCorquodale and Charles, 9th Earl Spencer — have naturally red hair.
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?
Rarest kind of redhead
Having red hair and blue eyes is the rarest hair/eye color combination possible. The odds of a person having both of those recessive traits is around 0.17%. Instead, most redheads have brown, hazel or green eyes, according to Medical Daily.
According to an article by evolutionary biology professor Mark Elgar, PhD, of the University of Melbourne, blue-eyed redheads are the absolute rarest, with 0.17% of the population having that combination of hair and eye color.
The rarest natural hair colour is red, which makes up only one to two percent of the global population. You commonly see these hair colours in western and northern areas of Europe, especially Scotland and Ireland. However, natural redheads may not exist for much longer.
Previous studies had shown that redheads inherit two versions of the MC1R gene that leads to red hair – one from their mum and one from their dad. Although almost everyone with red hair has two copies of the red-haired version of MC1R, not everyone carrying two red-haired versions is a redhead.
Red hair is caused by a mutation in the MC1R gene. It's also a recessive trait, so it takes both parents passing on a mutated version of the MC1R gene to produce a redheaded child. Because it's a recessive trait, red hair can easily skip a generation.
Red hair is relatively common in England, Iceland and Norway, too, while Germany, Sweden, Finland, The Netherlands and northern France are all ahead of the global average. Travel south through Europe and red hair becomes very rare.
Here's why. Red hair is caused by a recessive gene and it's not possible for this gene to simply die out. Even if there were no more redheads, people would still carry the recessive gene and that gene can appear at any time. Redheads may become rarer in the future, but they aren't going anywhere.
Lifespan: up to 20 years in captivity, 5-10 years in the wild.
Red hair is a recessive genetic trait caused by a series of mutations in the melanocortin 1 receptor (MC1R), a gene located on chromosome 16. As a recessive trait it must be inherited from both parents to cause the hair to become red.
