The key difference between epigenetics and normal genetics is that it’s easy to change epigenetic factors then change DNA.
Different epigenetic changes react to different environmental factors, but we don’t understand those well enough to have a good idea of what it takes for random epigenetic changes to happen. So it’s hard to rule out that someone knows what’s required for a given epigenetic change.
