When we use phrases like "generational trauma" being passed down, we end up misleading a lot of people on how genetics work. This phrase is often used in a political context, and to my knowledge there is not a good scientific foundation for it.
I'm familiar with generational trauma from a psychological perspective, but wouldn't a genetical/physiological aspect of it have to be self limiting?
I mean, I'm sure we all have millions of years of trauma in our genetic past.
