Researchers have identified what they say is the earliest known example of the domestic raising of horses. Writing in the journal Science, the researchers describe tracing the origins of horse domestication back to the Botai Culture of Kazakhstan, some 5,500 years ago. The researchers found evidence that horses were harnessed or bridled, and also that the horses were milked at the farm, in the steppe zones to the east of the Ural Mountains in Northern Kazakhstan. We'll find out more.
