People have relied on the modern horse to plow fields, charge into battle and traverse long distances for millennia. Horses have transformed human societies with every stride. But scientists have struggled to answer the seemingly simple of question of when and where these animals were domesticated.
It took an international team of more than 160 scientists to pinpoint the origins of the modern horse’s domestication: between 4,200 and 4,700 years ago near the Volga and Don Rivers in southwestern Russia. The team reported their findings this week in the journal Nature.
