CK:PS I really would like Troy to explain how the silvery gray iris evolved in L. alterna, if the ancestor of L. alterna did not suffer a population crash and then went through a genetic bottleneck. Tell us how the silvery gray iris is apparently so adaptive that it has replaced the ancestral golden brown iris completely (with but one possible exception) over the entire range of L. alterna.



Me: Why should I bother to indulge you with a "just-so" story? You asserted that ALL alterna have a silvery gray iris. I demonstrated that you were wrong. End of story. You were wrong, admit it.

BTW, Deserts are defined as areas that receive 10" or less of rainfall per year . . . the Trans-Pecos receives about 18" per year, on average . . . therefore it CANNOT, by definition, be considered a desert (yet another area that you are wrong).
