Blue-eyed people, listen up.
Ever wondered why your Why are their eyes the color they are? Well wonder no more.
According to researchers, every individual with blue eyes can trace their ancestry back to a lone European from between 6,000 and 10,000 years ago.
What method did they use to figure it out? Initially, all humans possessed brown eyes in different tones until a particular genetic alteration brought about the change.
The mutation occurs in a gene named HERC2 and this gene turns off OCA2, which is responsible for determining the amount of brown pigment our bodies produce.
That's why eyes appear blue.
Regarding descent from the same individual, the proof stems from the fact that everyone blue eyed person Alive today possess this identical genetic alteration.
Researchers estimate that merely 8 to 10 percent of people have blue eyes, and eye color doesn’t finalize during childhood; thus, the brown pigment might emerge over time, leading some blue-eyed kids to eventually develop brown eyes as adults.
Therefore, if you possess blue eyes, you should be aware that - your familial connections extend far wider than you may have previously imagined.
Researchers from the University of Copenhagen published findings on this topic.
Dr. Hans Eiberg from the Department of Cellular and Molecular Medicine said Initially, everyone had brown eyes. However, a genetic alteration impacting the OCA2 gene within our chromosomes led to the development of a 'switch' that essentially "deactivated" the capability to generate brown eye color.
The article was initially released on October 3, 2022.
