Both Bactrians and their one-humped cousins, the dromedaries (or Arabian camels [C. dromedarius], now extinct in the wild), originated in North America between 40 million and 45 million years ago.Wild Bactrian camels are very rare—at most, 950 remain in the wild, though this number may be much lower, since their broad habitat has made obtaining accurate population counts difficult. A number of human factors have contributed to their decline, including hunting for food and sport, as well as nuclear testing and illegal mining activity within their native habitats in Mongolia and China.
