From: A world in a grain of sand: human history from genetic data
Widely used population samples and worldwide genetic diversity. (a) Human Genome Diversity Project (HGDP) [30], (b) HapMap [60], (c) 1000 Genomes Project [7], (d) Genetic diversity in the HGDP samples [26]. In (a-c), samples are represented by circles with an area proportional to the sample size, placed according to their sampling location, but colored according to the predominant continental ancestry. Numbers and acronyms identify individual samples and details are given in Additional file 1; asterisks in (c) indicate populations that are still being collected. In (d), diversity measurements [26] were interpolated between sampling sites (dots); Australia and Greenland are grayed out because of a lack of data. See Additional file 1 for further details.
