The dromedary has not occurred in the wild for nearly 2,000 years. Wild dromedaries inhabited arid regions, particularly the Sahara Desert. The original range of the camel's wild ancestors was probably southern Asia and the Arabian peninsula. Its range included hot, arid regions of northern Africa, Ethiopia, the Near East, and western and central Asia. The dromedary typically thrives in areas with a long dry season and a short wet season. They are sensitive to cold and humidity, though some breeds can thrive in humid conditions.
