Membership of species in the orthogroups identified amongst protein-coding transcripts expressed in the CNS of M. musculus, X. tropicalis, D. rerio, L. stagnalis, D. melanogaster, and C. elegans. For clarity, only the 20 largest sets of shared orthogroups are shown. Dark and grey circles represent presence and absence, respectively, of the given species in each set of shared orthogroups. The number of orthogroups that each species is present in is shown in the inset bar graph. All species share the greatest number of orthogroups, followed by all vertebrates. Strikingly, of all three invertebrate species, L. stagnalis shares the greatest number of orthogroups with the three vertebrate species (1111)
