Blue eyed people listen up.

Ever wondered why your eyes are the colour they are? Well wonder no more.

Every blue eyed person is descended from a single European who lived around 6,000 to 10,000 years ago, according to scientists.

How did they work it out? Originally, all humans had brown eyes in various shades until there was a specific mutation that made the change.

Ancient formation discovered wrapped around Earth's core
A black hole is speeding through its galaxy giving birth to baby stars
Every blue eyed person on the planet comes from one single person
The mutation is a gene called HERC2 and it switches off OCA2, the gene that determines how much brown pigment we make.

So that's why eyes become blue.

As for being descended from the same person, the evidence for this is because every blue eyed person alive today has this same mutation.

neeli ankhon vaale log sunate hai.

kabhi sochaa he ki aapaki ankhen vah rang kyon hai jo ve hai?acchhee tarah se aashcharya nahin.

vaigyanikon ke anusaar, har neeli ankhon vaale vyakti ko ek ekal europea se utaara jaataa he, jo lagbhag 6,000 se 10,000 saal pehle rahata tha.

unhone ise kaise kaam kiya?mul rup se, sabhi manushyon ke paas vibhinn rangon main bhuri ankhen thim jab tak ki ek vishisht utparivartan nahin tha jisane parivartan kiya.

pracheen gathan kii khoj prithvi ke kor ke chaaron ore lipte hue he
ek blike hole apni akashganga ke madhyam se bachche ke sitaron ko janm de rahaa he
grah par har neeli ankhon vaala vyakti ek hi vyakti se aata he
utparivartan ek jin he jise HERC2 kaha jaataa he or yah OCA2 ko band kar detaa he, jin jo yah nirdhaarit karata he ki ham kitna bhure rang ke varnak banaate hai.

hamaare muft Indy100 saptahik samachar patr ke liye sin ap karen

to isiilie ankhen neeli ho jaati hai.

ek hi vyakti se utre jane ke liye, iske liye saboot yah he ki aaj jivit har neeli ankhon vaale vyakti ke paas yah ek hi utparivartan he.
