An In-Depth Look at Genetic Variation, covers Worldwide Human Relationships Inferred from Genome-Wide Patterns of Variation (about ~15 minutes long, interview with Rick Myers). Also, Wired blogs the most recent spate of papers (and gets a sound-bite from Marcus Feldman)….
Update: Readers might appreciate this from the Science paper:
However, the between-population variance is sufficient to reveal consistent population structure because subtle but nonrandom differences between populations accumulate over a large number of loci and yield principal components that can account for a major portion of the variation (21).
What’s reference “21”? A. W. Edwards, Bioessays 25, 798 (2003). Human Genetic Diversity: Lewontin’s Fallacy. Ding, dong….
