Selective sweeps Out-of-Africa

Here's a paper titled Genome Scans of DNA Variability in Humans Reveal Evidence for Selective Sweeps Outside of Africa (via Dienekes), something I've been hearing about for a year or so now from various people. The abstract notes: "A disproportionate number of these loci exhibited reduced levels of relative variability in non-African populations alone, suggesting that recent episodes of positive selection have been more prevalent outside of sub-Saharan Africa." In contrast, some have suggested that the prevalence of pale skin outside of Africa is evidence of relaxed selection.
