Fig. 7
The connected component size distributions plotted for the SD networks of different species on a log-log scale. The red lines in panels (a)-(c) represent the slope observed in the SD network of human. Observed distributions follow this slope on a log-log scale and a giant component is observed in most species. a. The group of primate species that includes human, gorilla and gibbon. b. The group of other mammalian species that includes rat, mouse and dog. c. The group of distinct species that do not belong to mammals: chicken, zebrafish and C. elegans. The SD network of C. elegans is the smallest one, thus we do not see a prominent giant component as in other species. d. The heatmap of similarities (1− Bray-Curtis dissimilarities) between connected component size vectors in all studied species. The dendrogram on top corresponds to hierarchical clustering of the species according to their similarities. We can see that the dendrogram, to some extent, reflects phylogenetic relationships between species (for example, presence of primate and mammalian branches)
