In the 18th and 19th centuries, the four South American camelid species were assigned scientific names. At that time, the alpaca was assumed to be descended from the llama, ignoring similarities in size, fleece and dentition between the alpaca and the vicuña. Classification was complicated by the fact that all four species of South American camelid can interbreed and produce fertile offspring. It was not until the advent of DNA technology that a more accurate classification was possible.
In 2001 the alpaca genus classification changed from Lama pacos to Vicugna pacos following the presentation of a paper Genetic analysis reveals the wild ancestors of the llama and the alpaca on work by Dr Jane Wheeler et al on alpaca DNA to the Royal Society showing that the alpaca is descended from the vicuña, not the guanaco.
The relationship between alpacas and vicuñas was disputed for many years, but Wheeler's DNA work proved it. However many academic sites have not caught up with this, so it is something well known to alpaca breeders who have read Dr Hoffman's book, and to Royal Society members who have access to the current classification data, but not more widely known.
