Man's Best Friend

In a recent article from the Science Codex entitled "Genetic study confirms: First dogs came from East Asia," Swedish scientists have concluded that man's best friend, the domesticated dog, did not originate from the century-believed  Middle East but rather from East Asia. Evolutionary genetics researcher Dr. Peter Savolainen states that the Asian region south of the Yangtze River was the main location for the domestication of wolves by humans.  Up until this point in genetics research, it was obscure and not an absolute where the exact location of the domestication of wolves began by humans, but after Y-chromosomal and mitochondrial DNA analysis, the signs point clear to the region close to southern China and Southeast Asia. Though this has spurred much debate, the Swedish geneticists have hard evidence that the DNA found in the Y-chromosomal and mitochondrial analyses is found the most in this region and therefore have had to have had the most domestication.
