The origin of domestic horses finally revealed
A study published on 20 October in the journal Nature proves that the modern domestic horse comes from the Pontic steppe in the northern Caucasus: the end of an intriguing mystery.
It is a mystery that has intrigued scientists for many decades: where does the domestic horse come from? And who domesticated it? It was also not known when this major event in human (and animal!) history occurred. We now have the answer: the modern domestic horse came from the Pontic steppe in the northern Caucasus.
This is the finding of a study published in the scientific journal Nature on 20 October 2021, and led by palaeogeneticist Ludovic Orlando at CNRS (Centre for Anthropobiology and Genomics of Toulouse). This has been a long-term project for Ludovic Orlando, who has been researching the origin of horse domestication for many years, and the 162 other researchers (archaeologists, palaeogeneticists, but also linguists) who have scrutinised the whole of Eurasia to sequence the genomes of 273 horses that lived between 50,000 and 200 BCE.
An effective strategy, since it found that around 2000 BCE a genetic profile previously restricted to the northern Caucasus had started to expand beyond its area of origin, to replace all wild horse populations from the Atlantic to Mongolia in a few centuries. These horses were probably favoured by human populations, as they were more docile and had a stronger backbone which made them easier to ride and load.
This fascinating discovery sheds light on the history of human migrations and human-animal relations, but it is also an opportunity for us to show you some wonderful images of the digs undertaken in recent years by Ludovic Orlando and his teams.
