Is it true that all people with blue eyes come from the same ancestor?

The overwhelming majority of people have brown eyes, which causes these with blue or inexperienced eyes, for instance, to draw consideration. The colour of the eyes, straight associated to genetics, is said to some sort of mutation all through the course of the story. However who had been the first to undergo it?

In keeping with a bunch of genetic researchers from the College of Copenhagen, the first mutation in blue-eyed people dates us again to a Danish household hundreds of years in the past. As defined, the shade variation from brown to inexperienced will be simply defined in the quantity of melanin the iris possesses. Melanin is nothing apart from the pigment present in most dwelling issues and that creates eye shade, in addition to different sections comparable to pores and skin or hair.

In the case of people with blue eyes, this quantity of variation in melanin is minimal. After reviewing the knowledge collected and uncovered in the journal Human Genetics, a single particular person was recognized – a father – and whose genes had been widespread to 155 people in Denmark. Not solely in that nation had been discovered references, but in addition associated to different people from Turkey and Jordan.

After the report it was concluded that all people with blue eyes could be linked to the same ancestor. On the opposite that these with brown eyes and the place the variation of melanin is nearly fixed.
