About Dog

The dog is a not later than 14000 years ago, even in May
Paper-cut dog photos (20) highlights a 16000 years ago, the southeast Asia have been domesticated a wild Wolf man from livestock. The dog, the Wolf is now under originated from the consensus, but around specific birthplace and time is controversial. So far, the first dog fossil evidence from Germany 14000 years ago is one of the mandible bone fossils, the other one is from the Middle East about 12000 years ago a small canine animal skeleton fossils, these archaeological evidence to support the dog is originated in southwest Asia or Europe, and on the other hand, the dog bone learn identification features tip the dog may be originated in the Wolf, the author proposed the dog east Asia origin said. In addition, different breeds of dogs in shape, he seems extremely rich diversity tend to dog originated in different geographical population of the Wolf hypothesis. So only on archaeology, it is difficult to provide clues to the origins of the dog reliable. Swedish scientists team of research of the five continents from 654 dog, analyzes their body a through the maternal inheritance is called "the mitochondrial DNA" the genetic material of the bases, found the dogs are almost the same with genes. They think, human and dog friendly origin can be traced back to 15000 years ago, when the first began, east Asia human domesticated animals such as Wolf, and in the long years of the domesticated dog gradually to Europe, and even across the bering strait brought to America. Think that east Asia, because in the east Asian region dog gene most abundant type, the scientists concluded that the region should genetic testing is the birthplace of the dogs, but not the past people always think of the Middle East. Peter gaza walter lai south said: "a lot of the early research based on the Middle East a small amount of archaeological materials, says the area is the dog place of origin, and in fact, there is some other domesticated animals, but not a dog." At the same time, through the comparison of the gene and the Wolf, and they believe that 15000 years ago, several different Wolf to differentiate into the dog. The study is from the two international study group has gone hand in hand with the land. On the other hand, the U.S. and Peru and other countries to the part of the scientific research team compared south and North America and Asia, Europe, the mainland of European colonists to dog and just before the American continent in Latin America and Alaska, the survival of the dog bases arrangement. Found Latin America and Sweden dog part of the genes from the past the Eurasian Wolf. This part of the gene in the 15 th century European colonists to America before it was in America on domestic dogs appeared. They think, the dog in east Asia origin and expand to the whole of Asia and Europe, and then in 14000 to 1.2 years ago by America's first group of settlers across the bering strait brought to America. Sweden a livestock expert thinks that the east Asia Johnson pearl is the first of a dog that the domestication is "very can convincing", America's first group of settlers took the dog, it shows before it for many years when the dog and Asian life together.
