Table 2. Number of species in which one or several genes gene are different from the ancestral version.

Genes have been ordered according to their variability, from highly to less variable and according to the number of species in which these genes are different from the ancestral version. For instance, all the species of Clade 1 (7) have rpl16 and rps16 different from their ancestor.
