Olaic acid is a type of signalling molecule conveying inform about death and decay among arthropods. The ancient chemistry of avoiding risks of pridation and disease appears to have something to do with it. An ancestor, tracing back to before those different categories of life split off from each other, probably developed this response. Though at some point along the way, some creatures started reacting to olaic acid to be chowed down on.
