Okay: In the debate between nature and nurture, we tend to assume that behavior is mostly from nurture, not nature. I've wondered about that assumption. So, from the OP, quite deeply zebra behavior is from nature, that is, genetics, "hard wired" as the OP says, and is quite solid since a lot of nurture won't change it. So, in the nature versus nurture debate, with zebras we have a good benchmark: Deep parts of behavior can be from nature and beyond nurture. So, we need to consider that possibility for species other than zebras. That is, even in behavior, quite generally we need to question the efficacy of nurture.
