Homeobox genes are involved in body plan formation and in the regulation of many developmental processes in bilateria. For this reason, the evolutionary history of Hox, ParaFlox, EHGbox, and NK homeobox gene families could be crucial to understand the evolution of molluscan body plans and phylogeny.

While whole-genome sequencing data have been available for four of the five major animal lineages - sponges (Porifera), flat invertebrates (Placozoa), jellyfish (Cnidaria), and animals with left-right symmetry, including humans (Bilateria) -Ctenophora remained the last major animal lineage for which there were no sequenced genomes.
