Kinship-distance curves for the pairs of individuals (q ≥ 0.8) according to log(distance) within the largest genetic clusters (n > 46; ‘LG east’, ‘LG west, ‘LG southwest’ and ‘Congo east’) and for pairs of individuals from the complete SSR dataset (‘ALL’). For the largest genetic clusters, decaying curves illustrate isolation by distance patterns (trend of decay of kinship Fij with distance). For the complete SSR dataset (‘ALL’), the decline of Fij at distances smaller than 50 km is the result of isolation by distance within each genetic cluster, while the steep decline of Fij at distances larger than 50 km probably reflects genetic divergence between genetic clusters as a result of ancient population fragmentation, since an increasing proportion of pairs of individuals belong to distinct genetic clusters with increasing distances
