Phylogenetic relationships between species analyzed and patterns of protein sequence divergence. a Phylogenetic tree showing evolutionary relationships between the species analyzed, with approximate divergence time estimated by a previous study [32]. Outgroup species used for most proteins are marked with an asterisk, murid species in pink, gerbil species in red. b-d Adjusted Sneath values for orthologous proteins compared between (b) two gerbil species, (c) two murid species, (d) the average of two murid species and the sand rat. Each point represents one protein; proteins encoded by genes in the extreme GC-rich region of sand rat are shown in pink or (for PDX1 and INSR) in red. Only one protein encoded within the extreme GC-rich region is present in (b) due to missing genes in the Mongolian jird genome assembly. Photographs from J.F. Mulley and Pixabay with permission
