Reconstructed phylogeny of 50 species using single-copy orthologous groups identified in their genomes. Phylogenetic tree is scaled by divergence time, with geological times indicated below and divergence times in Mya provided above. Laudakia sacra whose genome is sequenced in this study is highlighted in red. Green and red numbers indicate number of significantly expanded (+) and contracted (−) gene families, respectively. E., early; L., late; C., Cisuralian; S., Silurian; De., Devonian; Ca., Carboniferous; Pe., Permian; Tr., Triassic; Ju., Jurassic; Cr., Cretaceous; P., Paleogene; N. Neogene.
