"Although species distributions change through time owing to local extirpations, replacements and the colonization of new areas, we can use the current distribution of genetic lineages to infer the putative geographic location of past refugia. The concordance among phylogeographic patterns observed across the ungulate assemblage strongly suggests the presence of Pleistocene refugia in West and Southern Africa and a mosaic of refugia in East Africa."
