The Importance of Restoring Genome Information

I can see the whole culling and reproducing to drive evolution thing happening, but couldn't that work just as well if the environment called people due to them becoming too unfit for the environment? So there's slightly different things that I'm talking about. But my point is that just that me as an individual, I'm robust. My genome is robust. It's not anti fragile because, yeah, because there's not that, that feedback loop which means that if my genome starts going wrong, right, if I start to accumulate some mutations. And I have a, there's not like an external point of reference, right, I can't go to something else to appeal. What should
