Time resolved phylogenies of T. congolense and T. brucei. The savannah (a) and pan-African (b) clades are expanded below their respective trees. The coloured boxes correspond to countries of origin on the map of Africa (inset). STRUCTURE and hierBAPS groups are indicated by the white boxes. Timelines are in years before present and node values are posterior probabilities < 1. Arrowed nodes 1 and 2 are discussed in the text. The putative position of T. equiperdum STIB818 inferred from an independent ML tree (Additional file 10: Figure S6) is indicated in b
