The camelid family consists of the Old World camelids, the dromedary and Bactrian camels and the New World camelids, the llama, alpaca, guanaco and vicuana.
Many millions of years ago they originated as one species in North America. Some animals then migrated across the Bering Straits through Russia, China and into Arabia and Africa and deveoped into Old World camelids whilst others migrated south to South America and became the New World Camelids.
The dromedary camels, have one hump and are superbly adapted to the hot dry climate of the desert and usually found in places like Arabia, Africa, Pakistan and India, whereas the Bactrian camels have two humps and longer coats and more suitable for the harsh cold, dry environments of China, Russia and Mongolia.
The New World camelids are smaller and have warm woolly fleeces and can live in more mountainous areas so are usually found in South America such as Peru, Chile and Argentina.
In 1998 the Camel Reproduction Centre were the first to successfully cross the camel with the llama and produced hybrids called Camas.
