Tex19 and Sectm1 ML phylograms of all eutherian sequences. a Tex19 and b Sectm1. Bootstrap values greater than 65 % are symbolized by gray circles. Taxonomic groups of species are colored as follows: Haplorrhini = dark blue, Strepsirrhini = light blue, Scandentia = purple, Afrotheria = dark brown, Hystricognathi = dark red, Sciurognathi = orange, Bovidae = light green, further Laurasiatheria = dark green. Orange and light green branches depict Sciurognathi and Bovidae lineage sequences, respectively. Sectm1 sequences of Strepsirrhini species were not available in protein databases likely because genomes were still incomplete
