Which wild South American camelid serves as the primary ancestral lineage for the domesticated llama?
Answer
Guanaco
The llama is primarily descended from the wild guanaco. Early Andean peoples identified the guanaco as a suitable candidate for domestication, likely due to its larger physical stature, which made it ideal for carrying burdens. This selective breeding process, contrasting with the focus on fiber quality in the alpaca, led to the development of the modern llama from its wild guanaco ancestor.
