DNA persists, so of course behaviors in it also persist.
- sandworm101 3y agoBut can learned behavior persist in DNA? Could a gene activated by environmental triggers be later still be activeated after metamorphosis?
- mannykannot 3y agoMaybe via epigenetic changes? From my limited knowledge of the topic, I can imagine that a species might evolve such that, if the larva is in an unusually hostile environment (too cold, too dry...) then a gene controlling the imago's behavior gets methylated.
