Evolution of peptide signaling pathways and lunar rhythms. Reduced evolutionary tree representing the 2 principal lineages of animal evolution, protostomata and deuterostomata, arising ∼700 MYa from basal groups of sponges and cnidarians. Evolutionary changes in AKH/corazonin/ACP/GnRH receptor super family evolution data from ref. . Empty symbols (vertebrates and urochordates) represent loss of the receptor type. Symbols of moon phases indicate whether animals in groups show activity based on lunar rhythms (purple): Arthropoda, Christmas Island crabs; Mollusca, bobtail squid; although it should be noted that invertebrate spawning is more tightly coupled to the circadian cycle than to the circalunar cycle (21). Annelida group contains polychaete worm P. dumerilii discussed in the paper.
