Fossils Reveal Evolution of Early Nervous Systems in Ecdysozoans

A study published in Science Advances has provided groundbreaking insights into the early evolution of nervous systems in ecdysozoans, the group that includes insects and nematodes. Fossils from the Cambrian Kuanchuanpu Formation showed that ancient organisms like Eopriapulites had a single ventral nerve cord, supporting its ancestral role. Researchers suggest paired ...
