Also, look up epigenetics. More or less, it’s the ability of the environment to influence how genes are expressed. So it doesn’t always take breeding to select for more survivable traits, but environmental pressures to express desirable traits that may have been selected for at some point in the lineage of that species. Like remnant DNA.
This might not be 100% right but it’s close enough for me off the cuff laying in bed.
