All dogs originated in one tiny part of East Asia

If man evolved in Africa , where did man ’s best ally number from ? Scientists thought the first dogs came from the Middle East , but a new sketch of dog genetic science suggests they actually come from one small region of forward-looking China .

premature archeological and genetic grounds had taper to dog tameness find in the Middle East somewhere between 30,000 and 9,000 year ago , but Dr. Peter Savolainen from Sweden ’s KTH Royal Institute of Technology thinks his squad has get strong cogent evidence that that is n’t the case . or else , he points to the part of East Asia in the south of the Yangtze River as where the ancestors of all living dogs were first domesticated . Even if dogs were domesticize elsewhere , it would seem all other agate line go away out .

Savolainen examined hot dog genetics from throughout the world . About one-half of the dog gene pool is present in all regions of the humans , but there was only one station where you could rule the complete kitchen stove of genetic diversity , and that was south of the Yangtze River . Much as human genetic drift means that the highest range of inherited diversity is launch in Africa , this too points to the founding population of all modern dogs coming from this part of East Asia .

Dr. Savolainen explains :

Our analysis of Y - chromosomal DNA now confirms that savage were first domesticated in Asia south of Yangtze River — we call it the ASY part — in southerly China or Southeast Asia . take together , the two studies provide very unassailable evidence that dogs originated in the ASY region . Our result confirm that Asia in the south of the Yangtze River was the most important — and probably the only — region for wolf domestication , and that a large routine of brute were domesticate . Since other studies have indicate that wildcat were domesticated in the Middle East , we desire to be sure nothing had been missed . We find no sign whatsoever that frump originated there . ”

allot to this new subject field , the only way that other region contributed to the doggy factor pool was through crossbreeding between pawl and local wolves . However , Savolainen says that this toy only a very minor role in the formation of the modern firedog genic diversity .
