We haven't actually evolved to occupy an ecological niche that has us "mingling with" animals such as bats. This is not something we can "breed into" ourselves.

We haven't actually evolved to occupy an ecological niche that has us "mingling with" animals such as bats. This is not something we can "breed into" ourselves. Our primary strategy to limit exposure is to not have contact with animals with novel coronaviruses or others that can cross species. So we have to rely on our immune systems as our primary protection. Vaccines, theraputics, and public health measures are the only other strategies we have.
