Figure 2.
Phylogram showing the species used in the study, made using maximum likelihood on a concatenate of 4065 orthologous gene families. Expression (circles) and coding sequence assemblies (squares) with their source (colors) are indicated. Mus musculus strains (gray box, not included in the 33 species count), Murinae_seq data set (dashed lines box), and Total_seq data set (plain line) are delineated. Families and environments are color-coded, and precipitation is indicated. Transitions to arid environments are indicated by stars together with minimum transition ages (or maximum when not available) for data expression analysis.
