Thousands of days ago , a vast barter road called the Silk Road stretch from China all the path to Turkey and into Europe . Now it appear that modern horses are the outcome of trade and treks on this route .
Cambridge University animal scientist Vera Warmuth analyzed DNA from sawbuck in a wide range of locations on the former Silk Road , thousands of miles apart . What she discovered was a noteworthy law of similarity between them — particularly along the routes that were a trivial more temperate with mess of grass nearby . Horses in locating along hard and arduous route did n’t reveal the same genetic similarity .
On The Conversation , William Feeney describes some of the challenging findings from this study :
Ancient human trade facilitate universe mix in horses as far as 8000 km aside . Travelling along more arduous Silk Road routes , for instance across the Himalayas and the Tibetan Plateau , was probably more “ high-priced ” because less evidence of gene stream was seen in these areas . . . Warmuth find that horses from within the former Soviet Union land are no more similar to one another than Equus caballus from outside this area . In other words this study paint a picture that these knight are probable a Cartesian product of ancient and longsighted - term trading along the Silk Road itinerary rather than a merchandise of late trading practices .
The horses of contemporary Asia and Russia are likely the descendant of horses that ancient dealer grease one’s palms , or rode on , while wander G of miles on the Silk Road . This is further grounds that homo have ( often unwittingly ) been guiding the evolution of the animals around them for millennia .
