From: Expansion of the mutually exclusive spliced exome in Drosophila

The gain and loss of clusters of MXEs plotted onto the evolutionary tree of the Drosophila species (black and red numbers, respectively). Species abbreviations are D. simulans (dsim), D. sechellia (dsec), D. melanogaster (dmel), D. yakuba (dyak), D. erecta (dere), D. ananassae (dana), D. pseudoobscura (dpse), D. persimilis (dper) and D. willistoni (dwil), which are all part of the Sophophora branch, and D. virilis (dvir), D. mojavensis (dmoj) and D. grimshawi (dgri).
