The llama (Lama glama) is a species of domestic artiodactyl mammal of the family Camelidae, native to South America.It was domesticated by the native Andean people through artificial selection from the guanaco. According to recent DNA studies,[citation needed] this occurred, in principle independently in time and space, in sectors of northern Argentina, western Bolivia, northern Chile and southern Peru. This mammal was used to the maximum by the Inca Empire, which obtained meat and wool from it, and was also used as a pack animal (the only one before the arrival of the Spanish to America, with the exception of the Inuit sled dogs). .
