This essay is from 2002 (and most of the citations in the longer cited version were quite old even then), and a great deal has been learned through DNA studies since then. And some of his points of evidence such as the coloration on a piece of cave art are obviously flimsy. (And not to rely on an appeal to authority but he doesn't convincingly overcome being a non-expert commenting on an active scientific field, and I'm calling crackpot on the website.) There's good evidence that Homo sapiens sapiens first arrived in Europe during a warm period sometime around 45,000 years ago, then lived through the last glaciation maximum covering most of the continent with a peak around 18,000 years ago, driving the population through a harsh bottleneck that strongly selected for traits that aided survival in the cold climate. The population rebounded in numbers and in latitude from that bottleneck as the climate warmed again. A higher initial population under greater selective pressure for a longer period of time than elsewhere suffices to explain the resulting traits.
