[Mr. K]

are you a programmer?

[PatrickHenry]

No, I'm not a programmer. As you appear to be, then let me know if you can program a model giving the same result as the one in the article, with the same mutation and migration rates, but with a starting point of only 6,000 years in the past.

[Ichneumon]

are you a programmer?

I am. And I'd like to say that you're grossly misrepresenting the nature of computer modelling.
