Do you have any references on this? My understanding is that itβs in kind of a similar boat with intergenerational trauma that quantum mechanics is with certain schools of philosophy, and that the actual science of epigenetics supports a much more limited scope (responding to e.g famine and other current stressors in utero), so anything that could fall into the intergenerational realm would need to be passed down through the normal evolutionary process of populations experiencing selective pressure.
