Figure 6

Mapping of genome content using tree reconciliation performed by us (green) and ENSEMBL (blue). The differences between the two curves are due to differences between the species trees used: for example, we group Caenorhabditis elegans (nematodes) with arthropods (in the clade Ecdysozoa [35]) whereas it is positioned at the base of Bilateria in the species tree used by ENSEMBL. The inset shows the different mapping generated when using the tree alternative phylogenies among Afrotheria, Armadillo, and the remaining eutherians (groups A and B in Figure 5).
