I read a bit about eye colour on Wikipedia, since I really only wanted to find out why I am one of the "lucky" 22.3%( not sure if only reffers to USA) of white population to have blue eyes.

Turns out there was a genetic mutation in a common ancestor,

probably living in the northwestern part of the Black Sea region (around modern Romania) 6,000–10,000 years ago during the Neolithic revolution.Eiberg stated, "A genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally 'turned off' the ability to produce brown eyes."

I was surprised to see modern Romania was the territory where blue eyes appeared. I was expecting to be something like Russia, Finland, Norway or Sweden, since I thought that solar radiation is less around those parts and the melanin pigment is not as useful. Romania is in a calm temperate climate.
