- The evolution of nervous systems refers to the origin and development of nervous systems in animals (or metazoans)1. Nervous systems evolved from specialized electrical signaling cells called neurons, which adapted the mechanism of action potentials present in some single-celled and colonial eukaryotes1. One early theory on the evolutionary origin of the nervous system proposed a three-stage process involving the development of non-nervous effectors, receptors, and protoneurons2.

The evolution of nervous systems dates back to the first development of nervous systems in animals (or metazoans). Neurons developed as specialized electrical signaling cells in multicellular animals, adapting the mechanism of action potentials present in motile single-celled and colonial eukaryotes.en.wikipedia.org/wiki/evolution_of_nervous_systemsEarly theories on the evolutionary origin of the nervous system argued for a three-stage process: first, the development of non-nervous “independent effectors,” such as muscle cells; second, the appearance of non-nervous receptors responding to certain modalities in a receptor-effector mechanism; and finally, the formation of a “protoneuron,” from which primitive nerves and ganglia evolved.www.britannica.com/science/nervous-system/Evolu… - People also ask2 more answersmicrosoftstart.msn.com
