I'm not convinced. Assume it is accurate, there was one single blue eyed mutant that lived 10K years ago. Maybe the blue eyes were attractive and this individual was sexually prolific. Since blue eyes are recessive, none of their children would have had blue eyes. For more blue eyes to appear, there would have had to be lots of incest among the mutant's children. But what would have made the blue-eyed mutant's children more likely to pass on the recessive blue eyed genes if they didn't have blue eyes? For there to be so many blue-eyed individuals today, I think it is far more likely the blue-eyed mutation occurred many times.
