i don't see the argument in this. everything exists due to a process of everything else though. all things are essentially a natural state but in your view would be a selectioned process. one thing to look at is like white tail dear. the ones who had white tails for whatever reason were the ones to continue to breed and pass this gene down to what we have now. there were like offshoots in the evolutionary chain of the species that did not have white tails. for whatever reason they lost and died due to a myriad of different things. and failed to propogate. so now they exist as they do today as white tail dear. a selection process occured likely just from predators killing and destroying the ones without the white tails. in your view the existence of a white tail would be because another species influenced it. just because humans influence how other animals evolve doesn't make it unnatural. just like how other animals influencing other species does not make it unnatural. it is just that dogs are white peoples loser lives
