A camel is an even-toed ungulate within the genus Camelus, bearing distinctive fatty deposits, known as humps, on its back. There are two species of camels: the dromedary or Arabian camel has a single hump, and the Bactrian camel has two humps. Dromedaries are native to the dry desert areas of West Asia, and Bactrian camels are native to Central and East Asia. Both species are domesticated; they provide milk and meat, and are beasts of burden. Camels are equipped to deal with harsh desert conditions, such as flying sand. The camel's eyes are protected by long eyelashes and have an extra thin eyelid. It can see through this 3rd eyelid allowing them to find there way even in a harsh desert storm.
The term camel, (from the Arabic جمل, ǧml, derived from the triconsonantal root signifying "beauty"), is also used more broadly to describe any of the six camel-like creatures in the family Camelidae: the two true camels, and the four South American camelids: the llama, alpaca, guanaco, and vicuña.
The average life expectancy of a camel is 40 to 50 years. A fully grown adult camel stands 1.85 m (6 ft 1 in) at the shoulder and 2.15 m (7 ft 1 in) at the hump. The hump rises about 30 in (76.20 cm) out of its body. Camels can run at up to 65 km/h (40 mph) in short bursts and sustain speeds of up to 40 km/h (25 mph).
Fossil evidence indicates that the ancestors of modern camels evolved in North America during the Palaeogene period (see also Camelops), and later spread to most parts of Asia. The people of ancient Somalia or the Kingdom of Punt first domesticated camels well before 2000 BC.
