Similarity of expression levels and cell composition in pairs of species. Transcriptome similarities of expression levels (A) and cell-type composition (B) measured with Pearson correlation coefficients for pairs of species living in similar or different environments, belonging to the same or to different rodent families. (C) Transcriptome similarities of expression levels measured for pairs of species living in arid environments, belonging to the same or to different rodent families, after ancient or recent transitions (all independent pairs from Fig. 3A were taken). (D) Same but correlations measured on all differentially expressed genes detected in the study (N = 1325 genes).
