Evolutionary scenarios of the CHH family genes in Ecdysozoa. (A) Hypothesis accounting for two independent exon duplications originating the four-exon genes, which may have occurred on one side in a common ancestor of decapods and on the other side in a common ancestor of insects and branchiopods. (B) Hypothesis accounting for a single exon duplication originating the four-exon genes of insects, branchiopods and decapods.
