As you will hear in the fascinating video you are about to watch below, up until 10,000 years ago all humans were brown-eyed. A gene emerged, known as OCA2, that began to cause changes in the amount of pigment produced. The most incredible finding is that every blue-eyed person on earth today, is a direct descendant from one single individual who lived somewhere in Europe, 10,000 years ago!
A finding was made in 2006, after a Stone Age man who was well-preserved, was discovered in Spain. Upon examination, a gene named HERC2 was revealed to be the specific cause of blue eyes. Testing showed this gene to occur in African as well as Scandinavian populations; the mixture of these vastly different genetic mixtures is believed to have produced the first blue-eyed mutation. All blue-eyed people who have ever existed, are descendants of this first blue-eyed man!
