[November 15 AFP] (a part is updated) The place which compared with DNA of the present-day dog family animal DNA extracted from the fossil of the dog family animal, International research that a possibility that the origin of a dog (イエイヌ) is the wolf which inhabited Europe once is high was presented by the U.S. science journal science (Science) on the 14th.
Although the bone was the day after tomorrow from the garbage which hunter-gatherers dumped, the ancestor of the dog which is ? human being’s oldest intimate friend comes to take bold action gradually, and after he studied that more food was eaten, he is considered to have become attached to man.
It is said that it is concluded about the process of this domestication that the research team started 32,000 years before about 19,000 year ?.
The Turku university (University of Turku) and U.S. University of California at Los Angeles () of ? Finland [ University of California Los Angeles and ] Research teams, such as UCLA, analyzed the mitochondrial DNA extracted from the fossil of eight dogs of the prehistoric age, and ten wolf, and compared with 77 mitochondrial DNA samples extracted from the wolf which inhabits every corner of the earth now, or a dog.
? fossil is extracted from Russia, the Ukraine, Central Europe, the U.S., and Argentina, and it is said that an old thing is a thing of 30,000 years or more ago.
The DNA sample of the dog family animal of one present age was extracted in every corner of the earth, such as Israel, China, Sweden, and Mexico.
Mr. Robert Wayne (Robert Wayne) of U.S. University of California at Los Angeles who did ? research “the oldest イエイヌ makes Europe the origin.
It is said that this is a conclusion which is hard to avoid.”
The researchers who think that it is far from saying that the conclusion was reached are also in where domestication of wolf was first performed by ? one side.
In another research findings released by the science magazine in ? 2002, it was presupposed that it was the origin of a dog southern China.
Associate Professor Peta slowdown ライネン (Peter Savolainen) of the Sweden royal college of engineering (Royal Institute of Technology) which did this research indicates that the sample from the Middle East and China which is an important area is missing in this research.
The origin of the dog showed the view that it is in China too as “the system of the original dog seen only here exists in some numbers in southern China.”
To the China origin theory of ? dog, Mr. Olaf Thalmann (Olaf Thalmann) of the main writer of this research and Turku University, As a result of using the sample of DNA seeking エンシング (sequence determination) more perfect than a previous work or older time, it retorts having resulted in the conclusion that the origin of a dog is Europe.
Moreover, it is said that the dog was understood that a possibility of having crossed to the U.S. continent with European explorers is also high.
