Hedgehog and Segmentation Segmentation is a key characteristic of body plan organization in some of the largest animal groups, including annelids, arthropods, and vertebrates, but its evolutionary origins remain debated. In arthropod embryos, the Hed

SummaryTo elucidate the evolutionary origin of nervous system centralization, we investigated the molecular architecture of the trunk nervous system in the annelid Platynereis dumerilii. Annelids belong to Bilateria, an evolutionary lineage of bilate

For vision, insect and vertebrate eyes use rhabdomeric and ciliary photoreceptor cells, respectively. These cells show distinct architecture and transduce the light signal by different phototransductory cascades. In the marine rag-worm Platynereis ,
