How neurons first evolved is a long-standing debate. Some scientists believe that neurons evolved once and was then lost in some animal lineages (origin points shown in green). Others believe that they evolved twice, one time in the lineage that led to the rise of comb jellies, and a second time in the lineage that led to cnidarians and more complex animals (origin points shown in purple).
