Evolution of the dog. What is the origin of dogs? Where did the dog come from?
No one really knows when dogs became a man’s best friend. It was a long process of bringing Ice Age closer to the watchdogs of today’s fashion show.
New evidence, however, suggests it was considerably sooner than that. Swedish geneticist Pontus Skoglund printed a research 2015 in the journal Current Biology, describing his findings of a 35,000-year-old Siberian wolf bone. He reasoned that canine domestication could have first occurred 27,000 to 40,000 years ago.
According to Greger Larson, an archaeologist and geneticist, grey wolves were domesticated by humans somewhere in western Eurasia. He surmises individuals in the East were domesticating wolves at the same time.
ABOUT THE DOMESTIC DOG
Dogs were probably the first tame animals. They’ve accompanied humans for at least 20,000 years and maybe as many as 40,000. Scientists generally agree that all dogs, domestic and wild, share a frequent wolf ancestor; at some stage, grey wolves and dogs went to their separate evolutionary ways.
Today humans have bred hundreds of different domestic dog breeds–some of that could never live in the wild. Despite their many shapes and sizes all domestic dogs, from Newfoundlands into pugs, are members of the very same species–Canis familiaris.
Researchers think wolves were first brought to individual camps to scavenge for food. It takes about six to eight generations to domesticate a canine, according to a 40-year experiment that began in the late 1950s by Russian researcher Dmitri K. Belyaev.
Similarities to Wild Relatives
Domestic dogs nevertheless share many behaviours using their wild relatives. Both defend their territories and mark them by urinating on trees, rocks, fence posts, and other suitable sites. These odour posts serve notice to other dogs which a creature is occupying its own territory.
Many pet dogs also bury bones or favourite toys for future use, just as their wild relatives sometimes bury a kill to secure the meat for later feasts.
Dogs communicate in many ways. The scent is 1 method, another is bodily appearance. Body position, movement, and facial expression often convey a powerful message. Many of these signs are familiar even to humans, such as the enthusiastic tail-wagging of a happy dog or even the bared teeth of an angry or threatened animal. Vocallydogs communicate with a cacophony of sounds such as barks, growls, and whines.
Domestic dogs serve as more than companions; many make their keep by working hard. Dogs herd livestock, aid hunters, shield houses, and perform rescue and police work. Some special animals even direct the blind–a poignant symbol of the dog’s longstanding role as man’s companion.
There is even scientific evidence supporting the bond between humans and dogs. When folks look into each other’s eyes, we bond emotionally and release a hormone called oxytocin. A study led by Nagasawa found when dogs and individuals gaze into each other’s eyes, the identical hormone is released in both the humans and the dogs.
Dog breeds vary in popularity. From the 1890s, Saint Bernards were the No. 1 strain but since the 1990s, Labrador Retrievers are the favoured.
All dog breeds are distinguished by loyalty and it remains for us to choose between breeds according to the role required of them in our lives. For this we find each type of dog characterized by a specific thing, guard dogs, for example, are often larger than grazing dogs as well as grazing dogs are also have what distinguishes them, and perhaps speed and grace are the most important characteristics that you can notice, as well as grazing dogs are classified as one of the smartest types of animals on this planet.
