Figure 1.
Evidence for the ((Human, Mouse), Dog) Phylogeny
Shown are the ancestralness A(y|x) for a range of TEs families in a species x (mouse, mm; human, hs; dog, cf), compared with the two remaining auxiliary species y. Data are shown for all TEs that were present in at least 500 copies covering 50 kb or more in species x. When x is the outgroup, the ancestralness is expected to be consistent across auxiliary ingroup species y, while for ingroup species, some TE families may be ancestral (A > 0) for the second ingroup, but lineage-specific (A ≈ 0) for the outgroup. All three scatter plots support dog as the outgroup species.
