Inter-organismal signaling is essential for animals to navigate and survive in their natural environment, yet is unclear how these chemical communication channels may have evolved. Here, authors show that TYRA-2, an endogenous tyramine/octopamine receptor, is required for the chemosensation of an octopamine-derived pheromone and that this signaling system represents an inter-organismal communication channel that evolved via co-option of a neurotransmitter and its cognate receptor
