Evolution requires some amount of mutation, which is occasionally beneficial to the species. Species that were too good at preventing mutations would be unable to adapt to changing environmental conditions, and thus die out.
We’re aware of many species which evolved to extinction. I guess I’m looking for why there’s no plausible “path” in genome-space between this arrangement and an arrangement which makes fatal errors happen less frequently. EG why wouldn’t it be locally beneficial to the individual genes to code for more robustness against spontaneous abortions, or an argument that this just isn’t possible for evolution to find (like wheels instead of legs, or machine guns instead of claws).
