We better get used to considering human intervention as a method of evolution because someday their may be no natural habitat for them to be naturally selected from.Survival of the fittest
Is it that only the fittest digs survive? Or that only the ones best adapted to the Humans taste are bred, this does not lead to the other dogs no surviving? Dogs who fail to comply with the owners needs are not killed, and the breeding is forced on the dog it has no decision in the matter...
I never said humans where not natural, however the process in which the dogs are bred is determined by the owner and not the dogs.
