-
↵a Common genes are 646 genes that were shared by all species examined.
-
↵b Specific genes: some of these are genes conserved only in specific lineages, and especially 57 from vertebrate-specific genes, may have been related to the camera eye.
-
↵c Lost genes are genes that have been lost in the specific lineages.
-
↵d Conserved genes in out-group of bilateria are genes matched to proteins belonging to the out-group of bilaterian species but that do not match to proteins belonging to bilaterian species.
-
↵e These categories are not included in the ancestral gene set because they seem to have emerged after the divergence of protostomes and deuterostomes.
