Worms who's parents were exposed to a pathogen know to avoid that pathogen, despite never being exposed to the pathogen themselves. Worms who's parents did not have this experience do not know to avoid the pathogen. This is thought to be a result of small RNA based regulation of gene expression. https://www.cell.com/cell/fulltext/S0092-8674(19)30552-5?_returnURL=https%3A%2F%2Flinkinghub.elsevier.com%2Fretrieve%2Fpii%2FS0092867419305525%3Fshowall%3Dtrue Permalink 6
