Given the question: Information:  - The guanaco ("Lama guanicoe"), a camelid native to South America, stands between at the shoulder and weighs . Its color varies very little (unlike the domestic llama), ranging from a light brown to dark cinnamon and shading to white underneath. Guanacos have grey faces and small, straight ears.  - Camelids are members of the biological family Camelidae, the only currently living family in the suborder Tylopoda. The extant members of this group are: dromedary camels, Bactrian camels, wild Bactrian camels, llamas, alpacas, vicuñas, and guanacos.  - Vicugna is a genus containing two South American camelids , the vicuña and the alpaca . Previously thought to be descended from the llama , the alpaca was reclassified as part of Vicugna after a 2001 paper on alpaca DNA . The paper showed that the alpaca is descended from the vicuña , not the guanaco .  - An alpaca ("Vicugna pacos") is a domesticated species of South American camelid. It resembles a small llama in appearance.  - The vicuña ("Vicugna vicugna") or vicugna (both ) is one of two wild South American camelids which live in the high alpine areas of the Andes, the other being the guanaco. It is a relative of the llama, and is now believed to be the wild ancestor of domesticated alpacas, which are raised for their coats. Vicuñas produce small amounts of extremely fine wool, which is very expensive because the animal can only be shorn every three years, and has to be caught from the wild. When knitted together, the product of the vicuña's wool is very soft and warm. The Inca valued vicuñas highly for their wool, and it was against the law for anyone but royalty to wear vicuña garments; today the vicuña is the national animal of Peru and appears in the Peruvian coat of arms.  - The llama (Lama glama) is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures since the Pre-Columbian era.  - The Andes or Andean Mountains are the longest continental mountain range in the world. They are a continuous range of highlands along the western edge of South America. This range is about long, about wide (widest between 18° south and 20° south latitude), and of an average height of about . The Andes extend from north to south through seven South American countries: Venezuela, Colombia, Ecuador, Peru, Bolivia, Argentina and Chile.  - A camel is an even-toed ungulate within the genus Camelus, bearing distinctive fatty deposits known as "humps" on its back. The three surviving species of camel are the dromedary, or one-humped camel ("C. dromedarius"), which inhabits the Middle East and the Horn of Africa; the Bactrian, or two-humped camel ("C. bactrianus"), which inhabits Central Asia; and the critically endangered wild Bactrian camel ("C. ferus") that has limited populations in remote areas of northwest China and Mongolia. Bactrian camels take their name from the historical Bactria region of Central Asia (Yam & Khomeiri, 2015). Both the dromedary and the Bactrian camels have been domesticated; they provide milk, meat, hair for textiles or goods such as felted pouches, and are working animals with tasks ranging from human transport to bearing loads.
