Origin of Dog Domestication: How Dogs Evolved to Become Man’s Best Friend

Title: The Origin of Dog Domestication: How Dogs Become Background for Best Friends Reason and Reason: As a man's best friend, dogs are a common belief in contemporary humans and even accept it as a fact. However, the history of genetics and domestication behind the reasons for making dogs very compatible with humans is not well known to most people. Many people believe that it is Asian (research paper), but the timing of the branch and the geographical origin of domesticization of the dog caused a lot of controversy.

A dog's domesticated dog knows that the dog is a sweet and thoughtful animal, that she wishes to be loved, or is a best friend of a man, but before he is tame familiar There is none. Many people think that these dogs are tame from wolves, but many do not know that these dogs are wolves that are actually kept. Researchers believe that gray wolves are the main target of dog domestication. Scientists believe that the dog comes from a gray wolf and their dog has similar DNA.

A domesticated dog is the only animal tamed by humans before the start of agriculture. Therefore, the dog is not only a best friend of human beings, but also the oldest friend. I found that this dog can be used as a keeper or a hunter to teach us how to tame other species. In contrast, a cat recently appeared (10 BC BC) after starting construction of a house, farm, village. Artificial selection is the mechanism by which humans select natural diversity for their own purposes and is responsible for the evolution of domestic species. At the most basic level, domestication is dependent on some animals human food, shelter and reproductive management.

Dogs are a close friend of humanity for a long time. Based on the DNA research of the dog's genome and the discovery of archaeological remains of dogs traced back to 31,000 years ago, scientists estimate that dogs have been kept for approximately 50,000 years. I have built a strong friendship with. Meanwhile, cats are domesticated for 9000 years.
