There is no incongruity in the thought that in the very earliest period of man’s habitation of this world he created a friend and companion of some sort of aboriginal representative of our modern dog, which in come for its aid in protecting him from wilder animals, and in guarding his sheep and goats, he gave it a share of his food, a corner in his dwelling, and grew to trust it and take care of it. In all probability the animal was originally little else than an oddly gentle jackal, or an ailing wolf driven by its companions from the wild marauding pack to seek shelter in alien surroundings. One will well conceive the possibility of the partnership starting within the circumstance of some helpless whelps being brought home by the first hunters to be tended and reared by the girls and children. Dogs introduced into the home as playthings for the kids would grow to regard themselves, and be regarded, as family members
In nearly all elements of the globe traces of an indigenous dog family are found, the sole exceptions being the West Indian Islands, Madagascar, the eastern islands of the Malayan Archipelago, New Zealand, and also the Polynesian Islands, where there is no sign that any dog, wolf, or fox has existed as a real aboriginal animal. In the traditional Oriental lands, and usually among the first Mongolians, the dog remained savage and neglected for centuries, prowling in packs, gaunt and wolf-like, as it prowls these days through the streets and underneath the walls of each Jap city. No attempt was made to allure it into human companionship or to boost it into docility. It is not until we come to examine the records of the higher civilisations of Assyria and Egypt that we discover any distinct kinds of canine form.
The dog was not greatly appreciated in Palestine, and in each the Recent and New Testaments it is commonly spoken of with scorn and contempt as an “unclean beast.” Even the familiar reference to the Sheepdog within the Book of Job “However now they that are younger than I have me in derision, whose fathers I might have disdained to line with the dogs of my flock” isn’t while not a suggestion of contempt, and it is vital that the only biblical allusion to the dog as a recognised companion of man happens within the apocryphal Book of Tobit (v. 16), “Thus they went forth each, and also the young man’s dog with them.”
The nice multitude of different breeds of the dog and therefore the vast differences in their size, points, and general look are facts that create it difficult to believe that they might have had a common ancestry. One thinks of the distinction between the Mastiff and therefore the Japanese Spaniel, the Deerhound and also the modern Pomeranian, the St. Bernard and also the Miniature Black and Tan Terrier, and is perplexed in considering the chance of their having descended from a common progenitor. Yet the disparity is not any larger than that between the Shire horse and the Shetland pony, the Shorthorn and also the Kerry cattle, or the Patagonian and also the Pygmy; and every one dog breeders recognize how straightforward it’s to provide a selection in type and size by studied selection.
So as properly to perceive this query it is necessary first to contemplate the identity of structure within the wolf and also the dog. This identity of structure could best be studied in a comparison of the osseous system, or skeletons, of the 2 animals, which so closely resemble every other that their transposition would not simply be detected.
The spine of the dog consists of seven vertebrae within the neck, thirteen in the back, seven in the loins, 3 sacral vertebrae, and twenty to twenty-two within the tail. In each the dog and the wolf there are 13 pairs of ribs, 9 true and 4 false. Every has forty-two teeth. They each have 5 front and four hind toes, whereas outwardly the common wolf has so abundant the looks of a large, vacant-boned dog, {that a} widespread description of the one would serve for the other.
Nor are their habits different. The wolf’s natural voice is a loud howl, but when confined with dogs he will learn to bark. Although he’s carnivorous, he will conjointly eat vegetables, and when sickly he can nibble grass. Within the chase, a pack of wolves can divide into parties, one following the path of the quarry, the opposite endeavouring to intercept its retreat, exercising a considerable quantity of strategy, a trait that is exhibited by several of our sporting dogs and terriers when looking in teams.
A further important purpose of resemblance between the Canis lupus and also the Canis familiaris lies in the actual fact that the period of gestation in both species is sixty-three days. There are from 3 to nine cubs during a wolf’s litter, and these are blind for twenty-one days. They are suckled for two months, but at the tip of that time they are able to eat 0.5-digested flesh disgorged for them by their dam or perhaps their sire.
The native dogs of all regions approximate closely in size, coloration, type, and habit to the native wolf of these regions. Of this most important circumstance there are way too many instances to permit of its being looked upon as a mere coincidence. Sir John Richardson, writing in 1829, observed that “the resemblance between the North Yankee wolves and also the puppy of the Indians is therefore nice that the scale and strength of the wolf seems to be the sole difference.
It’s been advised {that the} one incontrovertible argument against the lupine relationship of the dog is the very fact that each one domestic dogs bark, while all wild Canidae specific their feelings only by howls. However the issue here is not so nice as it appears, since we have a tendency to apprehend that jackals, wild dogs, and wolf pups reared by bitches readily acquire the habit. On the other hand, doggies allowed to run wild forget the way to bark, while there are some that haven’t nevertheless learned so to specific themselves.
The presence or absence of the habit of barking cannot, then, be thought to be an argument to decide the query concerning the origin of the dog. This stumbling block consequently disappears, leaving us within the position of accepting with Darwin, whose final hypothesis was that “it’s highly probable {that the} pups of the globe have descended from 2 good species of wolf (C. lupus and C. latrans), and from two or three different doubtful species of wolves particularly, the European, Indian, and North African forms; from at least one or two South Yank canine species; from many races or species of jackal; and perhaps from one or more extinct species”; and {that the} blood of these, in some cases mingled together, flows in the veins of our domestic breeds.
