kudos to this researcher who noticed with his butterflies the same thing I notice with my bees (i.e. that they love him) and then set out to demonstrate, with serious and careful research methods, the persistence of caterpillar memories after metamorphosis, and also cross-generational epigenetics?? reminds me of those flatworm memory studies, impressive science. also the researcher is 10 years old https://www.youtube.com/watch?v=nhESxrqPjfU
