Heatmaps of pairwise species comparison of genomic features. Row and columns are species, ordered by taxonomy. I Heatmaps of dissimilarity of three genomic features for every comparison of species. The dissimilarity measure used is an inverted ratio of the pair. An inverted ratio close to 0, in cool colors, means the compared values are identical or very similar. An inverted ratio higher than 0.5, in warm colors, represents a more than 2-fold difference between the highest and lowest values in the pair. Features compared are (a) median protein length, (b) protein number, and (c) genome length. II Heatmaps of dissimilarity between distributions of gene-centric features for every comparison of species. The dissimilarity measure used is the Kolmogorov–Smirnov statistics. A statistic of 0 (in blue) means complete overlap between distribution and a statistic to 1 (red) no overlap at all, with intermediate ranges between the two extremes. Compared features are (d) protein length distribution, (e) protein domain number distribution, (f) gene length distribution, (g) isoelectric point distribution, and (h) GC content distribution. The heatmaps on the left section correspond to variables directly associated with protein length
