I think you are mis-representing the science on this purposefully. The dog has less genetic viabilty than the wolf - esp. the further they are removed (i.e. my dachshund challenge). If you are honest then you’ll fess up. I won’t hold my breath...
Dogs have much more genetic VARIABILITY than a wolf, and they display superior traits.
So your proposed ignorance of “de-evolution” means that we took a population of wolves, and from them derived much MORE genetic variability (in dogs from the daschund to the great dane), and derived increased abilities of use!
So why would bacteria have a mechanism to increase mutation rates during stress, if mutation just led to de-evolution?
And whatever happened to ‘microevolution’ being a ‘proven fact’?
How does your acceptance of ‘micro’-evolution square with your insistence that only “de-evolution” can take place?
Still no mechanism proffered whereby the dire wolf and other species would go extinct through accumulating mutations, but the wolf and ourselves would be protected.
