This bacterial faculty for trans-generational memory reminds me of human epigenetics. "Epigenetics refers to how your behaviors and environment can cause changes that affect the way your genes work. Unlike genetic changes (mutations), epigenetic changes are reversible" https://www.cdc.gov/genomics-and-health/epigenetics/index.ht...
