Fig. 2. RR framework to determine geographical structure.

Fig. 2

a, RR of being the same GPSC within a province (blue), between different provinces over increasing distance (red) and compared with geographically distant pairs (>1,000 km) (reference). (South Africa; n = 6,910). b–e, RR of having a time to most recent common ancestor (tMRCA) 0–5 years (b), 5–10 years (c), 10–20 years (d) and 20–200 years (e) ago within South African provinces (blue), across larger distances within South Africa (red), from South Africa to other countries in Africa (n = 1,157) (green), and from South Africa to countries outside of Africa (n = 2,944) (purple). All plots use a reference of pairs that are from distant provinces in South Africa (open triangle). f, RR of similarity over rolling 20-year windows of divergence times for pairs isolated within the same South African province compared with pairs from distant provinces in South Africa (>1,000 km apart). For a–f, plots are centred at the median and error bars represent 2.5 and 97.5 percentiles across posterior phylogenies.
