Can blue eyes be traced back to one ancestor?

Can blue eyes be traced back to one ancestor?

New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

Where did the mutation for blue eyes come from?

“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.

Does a single gene predict eye color?

Eye color was traditionally described as a single gene trait, with brown eyes being dominant over blue eyes. Today, scientists have discovered that at least eight genes influence the final color of eyes.

Who was the first blue eyed person?

A Stone Age man who lived about 7,000 years ago and whose buried bones were discovered in 2006 has turned out to be the earliest known person with blue eyes, a physical trait that evolved relatively recently in human history, a study has found.

Do blue eyes see better in the dark?

Blue eyes have less melanin compared to brown, but both colors are relatively common throughout the world. People with blue eyes tend to have greater light sensitivity. Night vision is often better among people with blue eyes.

What do blue eyes mean genetically?

People with blue eyes have a single, common ancestor, according to new research. A team of scientists has tracked down a genetic mutation that leads to blue eyes. The mutation occurred between 6,000 and 10,000 years ago. Before then, there were no blue eyes.

Can blue eyes be dominant gene?

The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
