Alpacas descend from vicuñas, not llamas

For centuries naturalists assumed alpacas came from llamas. DNA presented to the Royal Society in two thousand one flipped the story: Lama pacos became Vicugna pacos because alpacas descend from wild vicuñas. Shorter than pack-llama cousins, they were bred for fleece that still drives Andean and global fibre markets.

Two modern breeds dominate. Huacaya wool grows in crimped bundles; Suri hangs in straight locks. Both fibres fetch high textile prices, and trade sometimes stretches alpaca as a style label onto mohair or sheep lustre fabrics. Adults stand roughly eighty-one to ninety-nine centimetres at the withers and weigh about forty-eight to ninety kilograms. Herds traditionally graze Andean flats from southern Peru through western Bolivia, Ecuador, and northern Chile, typically between three thousand five hundred and five thousand metres, though farms now raise them worldwide.

Camelidae appeared in the Americas some forty to forty-five million years ago from Protylopus; later splits sent Camelini toward Asia and Lamini into South America. Vicuña and guanaco remains about twelve thousand years old occur across Peru; mummified llama and alpaca finds from Moquegua date roughly nine hundred to one thousand years old and already show two alpaca types. Moche art earlier featured alpaca images. Domestication is millennia deep, tuned to high pasture rather than desert caravans.

Social signals are blunt. Animals spit when distressed or asserting rank; males fight more, and alpha males may pin a rival's head and neck. Compared with llamas—valued as guardians and mountain porters—alpacas stay the fibre specialists. Reclassifying them under Vicugna closed a taxonomic wrong turn that had ignored shared size, fleece, and teeth with vicuñas. The fleece in a sweater still carries that corrected pedigree.
