 Although feral populations exist in Australia, India and Kazakhstan, wild camels survive only in the wild Bactrian camel population of the Gobi Desert.Humans may have first domesticated dromedaries in Somalia and southern Arabia around 3,000 BC, and Bactrian camels in central Asia around 2,500 BC, as at Shahr-e Sukhteh (also known as the Burnt City), Iran.Martin Heide's 2010 work on the domestication of the camel tentatively concludes that humans had domesticated the Bactrian camel by at least the middle of the third millennium somewhere east of the Zagros Mountains, with the practice then moving into Mesopotamia.
