Llamas

The llama is a domesticated South American camelid, widely used as a meat and pack animal by Andean cultures   since the Pre-Columbian era. 
The height of a full-grown, full-size llama is 1.7 to 1.8 m (5.6 to 5.9 ft) tall at the top of the head, and can weigh between 130 and 200 kg (290 and 440 lb). At birth, a baby llama (called a cria) can weigh between 9 and 14 kg (20 and 31 lb). Llamas typically live for 15 to 25 years, with some individuals surviving 30 years or more.
They are very social animals and live with other llamas as a herd. The wool produced by a llama is very soft and lanolin-free. Llamas are intelligent and can learn simple tasks after a few repetitions. When using a pack, they can carry about 25 to 30% of their body weight for 8 to 13 km (5–8 miles).

Early History

Llamas appear to have originated from the central plains of North America about 40 million years ago. They migrated to South America about three million years ago. By the end of the last ice age (10,000–12,000 years ago), camelids were extinct in North America.  As of 2007, there were over seven million llamas and alpacas in South America, and due to importation from South America in the late 20th century, there are now over 158,000 llamas and 100,000 alpacas in the United States and Canada. 

Pack Animals

These sturdy creatures are domestic animals used by the peoples of the Andes Mountains. (Their wild relatives are guanacos and vicuñas). Native peoples have used llamas as pack animals for centuries. Typically, they are saddled with loads of 50 to 75 pounds. Under such weight they can cover up to 20 miles in a single day. Pack trains of llamas, which can include several hundred animals, move large amounts of goods over even the very rough terrain of the Andes.
