Extended Data Fig. 7: Excess relatedness as a function of geographical distance.

Each point represents the model residual for one pair of individuals. The lines show best-fitting curves of the functional form y = 1/kx (allowing for horizontal and vertical translation). See Methods for details. A, B: Eastern and south-central Africa, with same-site pairs omitted from the analysis in B (grey: different sub-regions; blue: both Kenya, both Tanzania, or both coastal; yellow: both Malawi/Zambia). C: Western Europe. Note the different y-axis range. D: Northern and eastern Europe, where fit #1 includes all pairs, while fit #2 omits same-site pairs.
