Llamas Have been Medical Rock Stars in 2020, However They Have been Vital to Us Lengthy Earlier than Now

The Conversation

With their lengthy eyelashes, banana-shaped ears, upturned mouths, and stocky our bodies lined with curly wool, llamas appear to be creatures that walked out of a Dr. Seuss story. And now they’re celebrities within the US.


Due to their mild and docile demeanor, llamas are sometimes favorites at petting zoos. They seem at festivals and weddings and have even been deployed as remedy animals.

Llamas have additionally made medical information in 2020. Their immune programs produce nanobodies – tiny antibody fragments a lot smaller than human antibodies – which have potential as COVID-19 therapies.

Scientists are additionally testing artificial variations of llama nanobodies as applied sciences for treating illnesses comparable to cystic fibrosis.

However there’s rather more to learn about these partaking animals. In my work as a historian of Latin America, I’ve studied their lengthy relationship with people of their Andean mountain homelands.

These interactions have formed every part about llamas, from the size and shade of their wool to their tendencies and reproductive habits.

A camel lineage

Llamas are the descendants of animals referred to as wild guanaco, which have been domesticated in South America round 4500 BCE. Llamas and guanaco are two of 4 South American members of the camel household. The others are the alpaca and the vicuña, a wild species famend for its tender wool.

Breeders often pair feminine llamas with male alpacas to create offspring endowed with advantageous, precious alpaca wool. Male llamas are bred with feminine alpacas to extend the wool’s weight.


These animals have been essential to the financial system of the Incan Empire, which flourished in Peru from about CE 1400 to 1533. Incas used their wool to make cloth, which doubled as a type of forex.

The animals additionally supplied meat and carried items over some 25,000 miles of Inca roads.

However the Incas did not view llamas and their kin simply as livestock. Relatively, they have been deeply woven into the area’s tradition and non secular beliefs. Incas and pre-Incas sacrificed llamas and alpacas in non secular ceremonies to advertise fertility of their herds.

They served the animals’ meat at state-sponsored celebrations to honor rain gods. And so they sacrificed and buried these creatures on newly conquered lands to legitimize Inca presence.

The best wool

Archaeologists have unearthed mummified alpacas and llamas in Peru that have been greater than a thousand years outdated. The animals had been sacrificed and buried with beads, wool and silver items.

Evaluation of those completely preserved specimens revealed their handlers’ masterful selective breeding strategies. These animals had tender, wispy, rapidly rising wool – finer than right this moment’s greatest cashmere. So what occurred to the genes that produced such high-quality wool?


They disappeared.

After the Spanish took management of the Inca empire within the 1540s, Spanish rulers seen llamas and alpacas as beasts of burden or sources of meat.

Lots of the animals died from illnesses launched by the Spaniards’ imported sheep and cattle. It took almost 300 years for Peruvians to attain independence, and longer for indigenous Andean peoples’ inhabitants and conventional husbandry practices to renew.

Llama dressing

As we speak it is common to see llamas wearing colourful costumes in public squares in Andean cities. It is a longstanding cultural custom, symbolizing energy, respect, and reverence amongst indigenous folks, particularly in Bolivia and Peru.

For instance, the Qhapaq Qolla dance, celebrated every July in Paucartambo, Peru, acknowledges llamas and their herders as highly effective components of an Andean “cosmovision,” or understanding of the universe.

Andean cultures possess a holistic worldview that encompasses people, crops, animals, the land, rivers, mountains, rain, snow and, in fact, llamas. Many Andeans affiliate animals with supernatural beings.

Herders in Peru’s Ayacucho area imagine that their llama and alpaca flocks don’t belong to them – they’re the property of the “wamani” – spirits that reside inside waters or mountain peaks.


They imagine that llamas act as a vital conduit between folks and the wamani, and herders preserve that connection by means of ritual obligations that usually contain the animals.

They might adorn llamas, gown up the animals or “marry” llamas to one another on a marriage mattress. Docile animals that cooperate in these ceremonies are saved round, reproducing longer and creating future generations with easygoing temperaments.

The ‘trendy’ llama

Llamas first arrived within the US within the 19th century, imported for zoos and menageries. In 1914, the mayor of Buenos Aires famously gave one to then-Secretary of State William Jennings Bryan, although it wasn’t allowed into the nation as a result of it was contaminated with foot and mouth illness.

By the 1980s, llamas had turn out to be staple points of interest at petting zoos, gala’s, dude ranches, and personal events. Ranchers purchased them to chase coyotes away from their sheep.

Again-country guides loaded llamas onto jet boats and herded them into Cessnas for “llama packing” adventures and looking excursions.

Buyers who purchased llamas and alpacas as livestock did not fare so effectively, as there wasn’t a lot of a US marketplace for their milk or wool. Lobbyists managed to assist the trade within the early 2000s by together with alpacas in Part 179 deductions supposed to develop small companies.

These measures, which have been prolonged in 2010 and stay in power, deal with the acquisition of alpacas like tractors or different new gear.

No matter these incentives and llamas’ cultural reputation, llama possession within the US has declined from almost 145,000 animals in 2002 to underneath 40,000 in 2017.

Whereas llamas and alpacas might be present in each state, their populations are largely concentrated in Arizona and the Pacific Northwest.

Andean cultures have lengthy fostered relationships of reciprocity between people and different animals. As medical findings about llama nanobodies recommend, that outlook could also be wiser than indigenous South People might seemingly have imagined.
