, genetic studies show that only the llama is descended from it. The guanaco is not domesticated, but indigenous South Americans use its flesh for food and make its hide into clothing and other coverings and its bones into various implements. Encroachments on its grazing land have reduced its numbers. The guanaco is classified in the phylum ChordataChordata
, phylum of animals having a notochord, or dorsal stiffening rod, as the chief internal skeletal support at some stage of their development. Most chordates are vertebrates (animals with backbones), but the phylum also includes some small marine invertebrate animals.

(Lama guanicoe), a mammal of the genus Lama of the family Camelidae. It has a streamlined, slender body; the neck and extremities are long, the trunk shortened. The body measures 120–175 cm long; the height at the shoulder is 90–100 cm. The guanaco weighs 48–96 kg. Its body is covered with short (6–10 cm), brownish, wooly fur. The animal is found in the high-altitude arid semideserts of the Andes (up to 5,000 m) in South America. It is a polygamous herd animal. Mating occurs in midwinter; the female bears a single offspring after an 11-month gestation period. The guanaco feeds on grassy vegetation. It is hunted for its meat and hide, as a result of which its numbers have been sharply reduced.

There are policy prescriptions in the book that make great sense and could do much to avert the continued decline in wildlife: explore and develop the market for guanaco wool to allow wildlands "ranching" as an alternative to sheep farming on the steppes; expand the nascent ecotourism industry to demonstrate the high value of species currently considered nothing but pests by some of the locals; provide greater funding for surveillance and enforcement of existing protected areas, including Chile's flamingo reserve system and Argentina's national parks; and put into operation the well-conceived (thanks in large part to Conway himself) Coastal Zone Management Plan.
