Horses have been racing across the landscape for around 55 million years – much longer than our own species has existed. However, prehistoric remains show that at the end of the Ice Age, some 10,000 years ago, wild horses died out in the Americas and dwindled in western Europe, for reasons that are not clear. But they continued to thrive on the steppes of eastern Europe and Central Asia, where short grasses and shrubs grow on vast, dry stretches of land. Most scholars believe it was here that people domesticated the horse. However, the DNA of domestic horses is very diverse. This suggests they may be descended from a number of different wild horse populations, in several locations. (wa: Sir Wara 0878 7775 3771)
