Intensity distributions of CG independent selection and TA independent selection. The separability values of CG1 and TA1 spectra represent intensity distributions of CG and TA independent selections respectively. The \({\delta }_{1}\) is the background value. The abscissa represents species genome of species groups. From left to right, the species in each species group is arranged by its separability value of CG1 motif spectrum from small to large. a 112 animal genomes. The abscissa is species genome which is arranged by species groups. From left to right, the order is invertebrates, other vertebrates, other mammals, rodents and primates. b 63 plant genomes. The abscissa is species genome which is arranged by species groups. From left to right, the order is green algae, pteridophyte, monocotyledon and dicotyledon. c)73 Agaricomycotina genomes of fungi. d 118 Pezizomycotina genomes of fungi. e 54 Saccharomycetales genomes of fungi. f 200 archaea genomes. The archaea genomes are classified into five subgroups: Halobacteria (black), Methanomicrobia (green), Thermococci (blue), Thermoprotei (pink), and Methanomada (red). g 300 Eubacteria genomes. The Eubacteria genomes are classified into six subgroups: Actinobacteria (black), Proteobacteria (wathet blue), Cyanobacteria (green), Bacteroidetes (red), Firmicutes (blue) and Spirochaetales (pink)
