The ancestor of the dog was a wolf.
The ancestor of the dog is a wolf and has been recognized. But exactly where the dog originated, there has always been various opinions in the industry, but according to the research by relevant personnel, it is found that the world’s pet dogs are likely to come from China!
In the past, relevant experts have studied for the source of dogs, and found a 12,000 -year -old dog animal jawbone in Israel, so it is inferred that dogs only originate from the Middle East. However, according to the recent research results of Swedish scientists, the ancestors of pet dogs are likely to originate from China.
In Swedish scientists, after analyzing more than 500 kinds of dog hair samples around the world, they found that almost all dogs have the same gene library, and there are more genetic mutations in East Asian dogs. Origin from East Asia. The results of this research have been published in Science magazine. Researchers pointed out that about 15,000 years ago, humans living in China or nearby have tamed wild wolf to develop home dogs. They are the ancestors of the family dogs. Later, with the migration of human beings, the family dog was taken to Europe, and during the 12,000 to 14,000 years, the hunter brought from the Bai Ling Strait to North America, and then brought it to South America and even around the world. Since then, house dogs have spread all over the world and breed different varieties. According to the latest genetic research results, all dogs, including Newfoundland dogs in the Americas, and even Eskimo dogs, are descendants of the Asian wolf.
In summary, the researchers infer that the development history of the family dogs is roughly as follows:
15000 years ago: the first batch of wolves of a blogger in Asia, the predecessor of the house dog.
14000 years ago: House dogs moved to all parts of the world with humans, including Europe and Africa.
12000-14000 years ago: Dogs were scattered to Australia.
12000 years ago: Dogs only appeared in the Americas and Israel.
