Histone \u2018replacement\u2019 experiments have similarly found a lack of phenotypes for some modifications. Do these findings foretell a paradigm shift for the histone code hypothesis? Here, we discuss these results through the lens of ecology, evolution, and development (\u2018eco-evo-devo\u2019) to provide context. We then highlight recent \u2018top-down\u2019 approaches, which start from environmentally influenced phenotypes and then attempt to identify causal mechanisms; placing function before molecule. Using this strategy, recent work in invertebrates has found key roles for histone acetylation and small RNAs in developmental plasticity. The synthesis of traditional \u2018bottom-up\u2019 with new \u2018top-down\u2019 approaches can resolve which molecules are epiphenomenal and which are truly epigenetic.","protected":false},"excerpt":{"rendered":"<p>Recent studies have reported that catalytically dead histone-modifying enzymes can rescue the function of their null alleles.
