Do people with blue eyes all share a common ancestor?
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.
Who are all blue eyed people descended from?
blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family.
Can brown and blue eyes make blue?
If both of you have brown eyes, then there is generally a 25\% chance that the baby will have blue eyes if both of you carry the recessive blue-eye gene. But if only one of you has a recessive blue-eye gene, and the other has two brown, dominant genes, then there is a less than 1\% chance of the baby having blue eyes.
What are facts about blue eyed people?
Human beings have two genes for eye color; one is inherited from the father and the other from the mother. Since brown eyes are dominant, a person could have a gene for blue eyes and one for brown eyes and he or she would have brown eyes. For someone to have blue eyes, he or she must have two genes for blue eyes.
Is everyone with blue eyes related?
If you have blue eyes, you are very likely related to every other blue-eyed person on the planet! That’s the word from researchers at Copenhagen University in Denmark, who conclude that everyone with blue eyes descends from a single “founder,” an ancestor whose genes mutated 6,000 to 10,000 years ago, reports USA Today.
Who were the first blue eyed people?
Blue eyes are the result of a mutation that first occurred around 6,000 to 10,000 years ago. Piotr Krzeslak/Shutterstock. Every blue-eyed person on the planet is descended from a single European who lived around 6,000 to 10,000 years ago, and who first developed a specific mutation that accounts for the now widespread iris coloration.
Who was the first person to have blue eyes?
Scientists pinpointed the first person believed to have had blue eyes after discovering his well-preserved remains in a cave system in north-west Spain, in 2006.
