‘Blue eyes hypnotize teri karti hai mainu…’ You must have heard this rap of Yo Yo Honey Singh. If you haven’t heard then Lata Mangeshkar and Rafi Sahab’s song…‘Teri neeli-neeli aankhon ke dil pe teer chal gaye, ye dekh dekh duniya wale ke dil gaye…’ >,You must have definitely heard it. You might be wondering why these songs started being hummed at the beginning of the news. Actually, the matter is related to ‘blue eyes’ only.
The fewer blue-eyed people there are in the world, the more has been said and heard about them. Scientists believe that only 8 to 10 percent of people in the world have blue eyes. With increasing age the blue color of the eyes may also disappear. However, the eyes of many people always remain blue.
Those with blue eyes are different from the rest of the world
New research has come on people with blue eyes. It states that every blue-eyed person is a descendant of a European person. He is a descendant of a European man who lived approximately 6000 to 10000 years ago. Even though you may find this shocking, it has been said in the study that a gene mutation has been identified in this study, which happened about 6 to 10 thousand years ago. Professor Hans Eyberg of the Department of Cellular and Molecular Medicine at the University of Copenhagen said that a genetic mutation affecting the OCA2 gene in our chromosomes resulted in a change that literally affected brown eyes.
How did the mutation happen
Research says that the mutation is in a gene called HERC2, which turns off OCA2. This gene determines how brown or black our eyes will be. When the OCA2 gene is turned off, the eyes are blue. As far as descent from the same European person is concerned, the proof is that every blue-eyed person alive today has the same mutation that happened in that person 6 to 10 thousand years ago.
Eyes are generally brown
Scientists say that generally all humans have brown eyes. However, their color may vary. Scientists say that people whose eyes are not fully developed in childhood, have blue eyes. However, they may become completely brown as adults.
