Farmer catching horses in north-central Kazakhstan. Ludovic ORLANDO / CAGT / CNRS Photothèque The modern horse was domesticated around 2200 years BCE in the northern Caucasus. In the centuries that followed it spread throughout Asia and Europe. To achieve this result, an international team of 162 scientists collected, sequenced and compared 273 genomes from ancient horses scattered across Eurasia. Horses were first domesticated in the Pontic-Caspian steppes, northern Caucasus, before conquering the rest of Eurasia within a few centuries. These are the results of a study led by paleogeneticist Ludovic Orlando, CNRS, who headed an international team including l'Université Toulouse III - Paul Sabatier, the CEA and l'Université d'Évry. Answering a decades-old enigma, By whom and where were modern horses first domesticated? When did they conquer the rest of the world? And how did they supplant the myriad of other types of horses that existed at that time? This long-standing archaeological mystery finally comes to an end thanks to a team of 162 scientists specialising in archaeology, palaeogenetics and linguistics.
