In addition to this, however, there nuts( have gone on from the very first, beside: the varying influences of new climate, food, and general en ironment, a certain amount of selective breed ing.
It has been huh by Professor Shaffer and others that the first motive to domestication of the dog was to provide a resource against the recurring famine: that millet aboriginal life, while others suppose the animal's aid in hunting first made it valuable. I_ Ild011bttlliV, then as vow, the dog was eaten on oreasion. 1.iit it would certainly make itself so useful as a watch-dog and a hunter as quickly to win regard; and there is no doubt that the personality of the animal would appeal to the affection of the prim' vat savages as it does today. No other human beings
are regarded as so rude and autochthonous as the northern Australians, yet while they eat both the wild and tame dingos. and use the latter in hunting. they regard many of them as pets, lavish affection upon them, and even nurse the puppies at the women's breasts. In recognition of these qualities, the hest or most interesting puppies and older dogs would naturally be saved when :toy were to be killed for food or other purpose. In such isolated circumstances as those of the Australians, where there is free and con stant intercourse between the wild stock and the tame. this would have little effect: in general, where the mixture of several wild breeds had already produced diverse hybrids, the nneon scions selection thus brought about would soon he effective, am] would he followed, a: civilization be”an, with a more intelligt nt and definite kind of choice, which must have originated selective breeding long before any history of it begins. It must have been intelligently and persistently practiced, in fact, long before the earliest civil ized records. for monuments inscribed four or live thousand years ago bear pictures of widely diversified and perfectly bred races of dogs, such as greyhounds.
