Who is the common ancestor for blue eyes?
Who is the common ancestor for blue eyes?
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.
Is ocean blue eyes rare?
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.
How did Africans get blue eyes?
The mutation for blue eyes, a change in the HERC2 gene, is thought to have first appeared around the Black Sea 10,000 years ago and then gradually moved west. Because the gene is recessive, blue-eyed people must have two copies, one from each parent.
Are blue eyes a trait of inbreeding?
However, the gene for blue eyes is recessive so you’ll need both of them to get blue eyes. This is important as certain congenital defects and genetic diseases, such as cystic fibrosis, are carried by recessive alleles. Inbreeding stacks the odds of being born with such conditions against you.
What is the second rarest eye color?

Are blue-eyed people related to the Black Sea?
And all blue-eyed people are genetically related to a person who lived in the Black Sea region sometime between 6 – 10,000 years ago. The research was published in the Journal of Human Genetics. A mutation in a gene called OCA2 came into being nearly 8,000 years ago.
Where did the blue eye gene come from?
Savage on January 21, 2017: The blue eye gene came from one fallen angel with blue eyes and dark skin. It’s in the book of Enoch. Rodrigo Sebidos from Zone2 Brgy.Guadalupe, Baybay City, Leyte, Philippines on September 23, 2016: Very possible because of mutation, a sudden heritable change.
What is the origin of black people with blue eyes?
