Abstract: An arthropod specimen from an early Cambrian deposit in China shows a nervous system very similar to that of modern insects and crustaceans, suggesting that insect and crustacean nervous systems evolved from a relatively complex ancestral one, and that simple animals, such as branchiopod shrimps, have evolved a marked reduction in the complexity of their nervous systems.
