General History of Dogs.
There is no contradiction in the idea that in the same period of the first human settlement in the world, got a friend and companion of some indigenous representative of our modern dog, and that in return for helping to protect nature and preserve his sheep and goats, gave him a share of his meal, a corner of the apartment and grew to trust him and care for her. Probably the animal was a little more than an unusually mild Jackal, a wolf or a sick run by his comrades from the marauding pack to seek shelter in a foreign environment. We can also imagine the possibility of starting a partnership in a situation with some small defenseless dogs brought by the early hunters to be cared for and reared by women and children. Entering the house the dogs as toys for children are regarded and treated as family members
In almost all regions of the world traces of indigenous dog family, excluding only the West Indies, Madagascar, the eastern islands of the Malay Archipelago, New Zealand and Polynesia, where n 'there is no sign that any dog, wolf or fox that was a true native animals. In the old Eastern European countries, and are generally among the early Mongolians, the dog was wild and neglected for centuries, sneak in packages of lean as a wolf, as it now prowl the streets and on the walls of every Eastern city. No attempt was made to lure it into human companionship or to improve administration. Not because you get to examine their accounts in the higher civilizations of Assyria and Egypt that we discover the different varieties of cat form.
The dog was not much appreciated in Palestine and in the Old and New Testaments, is spoken with scorn and contempt as a "dirty animal". Even the familiar reference to shepherds in the Book of Job "But now those younger than me to shame if fathers despised for dogs of my flock" is not without a hint of contempt, and it is important that only the biblical references dog as a companion of man found in the apocryphal Book of Tobit (v. 16): "So he went all the two young dogs with them."
Large number of different breeds of dogs and significant differences in their size, scoring, and general appearance are facts which make it hard to believe they could have a common ancestor. We believe that the difference between the Mastiff and the Japanese Spaniel, Deerhound and the fashionable Pomeranian, and Bernard Black and Tan Terrier and Miniature are helpless to consider the possibility derived from a common ancestor. But the difference is not greater than that between the Shire horse and Shetland pony, Shorthorn and the Kerry cattle, or Patagonia, and scrubby, and all dog breeders know how easy it is to produce different types and sizes are investigated by elections.
To understand this issue must first examine the structure of the identity of a wolf and a dog. The identity of this structure can be better evaluated in relation to the bone
system, or skeletons of two animals so similar that their transfer would not be easy to detect.
Spine of a dog consists of seven cervical, thirteen in the lumbar region of his back, seven, three sacral spine, twenty to twenty-two in the tail. In both dogs and wolves, thirteen pairs of ribs, nine true and four false. Each has forty-two teeth. They both have five front and four rear, while outside the common wolf has so much the emergence of large dogs, bare legs, a popular description of a serve others.
And their habits different. Wolf natural voice is a loud cry, but then only with dogs will learn to bark. Although it is carnivorous, he also eat vegetables, and when he is sick nibble grass. In hunting, wolves will be divided into parts, the trail follows the quarry, the other trying to intercept their retreat, carrying a significant amount of strategic function that is manifested by many of our dogs burrows when hunting in teams.
Another important point in the guise of Canis lupus and Canis familiaris lies in the fact that the period of gestation in both species is sixty-three days. There are three to nine wolf pups in a litter, and they are blind in the twenty-one days. They are grown in two months, but at the end of this period, which is able to eat half the meat consumed them disgorged by the mothers or even their father.
Dogs are located in every region around the approximate size, color, shape and habit native wolf of those regions. Critically, there are too many cases, to enable him to treat them as pure coincidence. John Richardson, writing in 1829 stated that "like North American Indians, wolves and dogs are so great that the size and strength of the wolf appears to be the difference.
It was suggested that only a convincing argument against the lupine relationship dog is that all dogs bark, while all wild Canidae express their feelings only howls. But the difficulty here is not as great as it looks, because we know that jackals, wild dogs, wolves and pups reared by bitches readily acquire the habit. On the other hand, dogs can romp forget to bark, although there are those who have not yet learned to speak.
The presence or absence of a habit of barking can be considered as an argument to determine the origin of the dog. This problem disappears, leaving us unable to agree with Darwin, whose final hypothesis was that "it is likely that dogs in the world comes from two good species of wolf (C. lupus and C latrans), and two or three other doubtful species of wolves namely, the European Commission, India and North Africa is at least one or two South American species of dogs, several breeds or species of the Jackal, and perhaps one or more species extinct, and his blood, in some cases with flows in the veins of our domestic races.
