Common ancestors?
Who would have thought that?! Blue-eyed people we see from now with completely different eyes. Because they all have something in common!
Thousands of years ago, there were only brown-eyed people, now around 10 percent of the world's population has blue, green or gray eyes.
Between 6, 000 and 10, 000 years ago, according to a new study, people in Europe had mutated the OCA2 gene . This gene determines the melanin content of the iris and thus the eye color. The first blue-eyed people were born.
Now it is believed that all blue-eyed people have European ancestors . Researchers believe that the gene mutation first occurred in the Mesolithic (9, 500 to 4, 500 BC) and later spread through the growing population towards the Baltic and Northern Europe, where most people still live with blue eyes.
Do all blue-eyed humans have an ancestor?
The fact that all blue-eyed humans have the same gene mutation is convincing evidence for this theory, although it has not yet been possible to clarify exactly what triggered this gene mutation. Incidentally, the first person with blue eyes lived in Spain around 7, 000 years ago. Although the eyes of the skeleton had long since decayed when he discovered it, it could be clearly determined by DNA comparison that the northern Spaniard had blue eyes.
