Companionship has little to do with shared DNA; otherwise there would be no wars between humans. Dogs make good companions because of several thousand years of selective breeding for the traits that appeal to us. Wolves and African hunting dogs make very poor companions. Pets also seem to appeal to our desire to nurture and this may require a species to which we feel clearly superior. Perhaps chimps are just too similar to us, for us to be comfortable with a master-servant relationship.
