On November 3rd, 2022 we talked with Harold Zakon about the cells that enable weakly electric fish to generate electric fields around themselves and to use them as a sensory and social communication system.  Harold described the remarkable independent evolution of this capability twice, in the African and in the South American electric fish, and the host of coordinated genetic changes that were required to create this entirely new sensory modality.
