being that blue eyes range from Iceland to Israel, Its kind of hard to imagine a single person's mutation within the past 6-10 thousand years spreading so fast and being present in such a huge geographic swath, isnt it possible that the same or similar mutation occured in different individuals, who were enduring the same environmental conditions? It would be like saying all light skinned people share a common ancestor that endowed them with that trait, yet in reality we know that this occured not through a single person's contribution, but through a population's collective adaptation to the environment and overall UV index.
earlier I had read an article stating that blue eyes and blond hair spread as fast as it did because of sexual selection, the first or early individuals to exhibit this new trait/mutation stood out amongst thier female peers, this unique feature secured the accelerated spread of thier genes, exponentially distributing the mutation from the time it arose somewhere between the Baltic and Black sea.
who knows, I really like blue eyes, but blond hair is not so important to me, as in men it may coincide with thin, prone to balding hair, and with women usually fades to darker tones after childbirth, a disharmonious pigmentation comprised of light skin, light eyes and dark hair has always come off to me as most striking, but then again, that could be narcissus talking
