Alpacas are a domesticated member of the camel (camelid) family. The camelid family also includes llamas, guanacos, and vicunas from South America, and the Bactrian and Dromedary camels from Asia and Africa. This family of animals originated on the plains of North America about 10 million years ago. A common ancestor to the South American camelids migrated to South America about 2.5 million years ago.
Two wild species, vicuñas and guanacos, emerged.
