Vicugna pacos

The alpaca (Vicugna pacos) is a species of South American camelid. It is similar to, and often confused with, the llama. However, alpacas are often noticeably smaller than llamas. The two animals are closely related and can successfully cross-breed. Alpacas and llamas are also closely related to the vicuña, which is believed to be the alpaca's wild ancestor, and to the guanaco. There are two breeds of alpaca: the Suri alpaca and the Huacaya alpaca. Alpacas are kept in herds that graze on the level heights of the Andes of Southern Peru, Western Bolivia, Ecuador, and Northern Chile at an altitude of 3,500 m (11,500 ft) to 5,000 m (16,000 ft) above sea level. Alpacas are considerably smaller than llamas, and unlike llamas, they were not bred to be working animals but were bred specifically for their fiber. Alpaca fiber is used for making knitted and woven items, similar to sheep's wool. These items include blankets, sweaters, hats, gloves, scarves, a wide variety of textiles and ponchos in South America, and sweaters, socks, coats and bedding in other parts of the world. The fiber comes in more than 52 natural colors as classified in Peru, 12 as classified in Australia, and 16 as classified in the United States. Alpacas communicate through body language. The most common is spitting when they are in distress, fearful, or mean to show dominance. Male alpacas are more aggressive than females, and tend to establish dominance of their herd group. In some cases, alpha males will immobilize the head and neck of a weaker or challenging male in order to show their strength and dominance. In the textile industry, 'alpaca' primarily refers to the hair of Peruvian alpacas, but more broadly it refers to a style of fabric originally made from alpaca hair, such as mohair, Icelandic sheep wool, or even high-quality wool from other breeds of sheep. In trade, distinctions are made between alpacas and the several styles of mohair and luster. An adult alpaca generally is between 81–99 centimetres (32–39 in) in height at the shoulders (withers). They usually weigh between 48–84 kilograms (106–185 lb). Alpacas have been domesticated for thousands of years. The Moche people of Northern Peru often used alpaca images in their art. There are no known wild alpacas, and its closest living relative, the vicuña (also native to South America), is believed to be the wild ancestor of the alpaca. The family Camelidae first appeared in Americas 40–45 million years ago, during the Eocene period, from the common ancestor, Protylopus. The descendants divided into Camelini and Lamini tribes, taking different migratory patterns to Asia and South America, respectively. Although the camelids became extinct in North America around 3 million years ago, in the South flourished with the tribes we see today. It was not until 2–5 million years ago, during the Pliocene that the genus Hemiauchenia of the tribe Lamini split into Palaeolama and Lama, the latter would then split again into Lama and Vicugna upon migrating down to South America. Remains of vicuña and guanaco have been found throughout Peru for around 12,000 years. Their domesticated counterparts, the llama and alpacas have been found mummified in the Moquegua valley in the south of Peru dating back 900 to 1000 years. Mummies found in this region shows two breeds of alpacas. More precise analysis of bone and teeth of these mummies has demonstrated that alpacas were domesticated from the Vicugna vicugna. Other research, considering the behavioral and morphological characteristics of alpacas and their wild counterparts, seems to indicate that alpacas could find their origins in Lama guanicoe as well as Vicugna vicugna, or even a hybrid of both.
