The smell of recent death or injury that repels living relatives of insects has been identified as a truly ancient signal that functions to avoid disease or predators, biologists have discovered. David Rollo, professor of biology at McMaster University, found that corpses of animals, from insects to crustaceans, all emit the same death stench produced by a blend of specific fatty acids. The findings have been published in the journal Evolutionary Biology. (source: sciencedaily.com)
