Many multicellular animals respond to disease-causing agents, termed pathogens, using an evolutionarily conserved defence pathway called the cGAS–STING pathway1,2. Reports in the past few years of cGAS- and STING-like proteins in bacteria raised the possibility that this pathway is more evolutionarily ancient than was previously thought3–5. Writing in Nature, Morehouse et al.6 demonstrate that a
