 The descendants divided into Camelini and Lamini tribes, taking different migratory patterns to Asia and South America, respectively.Although the camelids became extinct in North America around 3 million years ago, it flourished in the South with the species we see today.It was not until 2–5 million years ago, during the Pliocene, that the genus Hemiauchenia of the tribe Lamini split into "Palaeolama" and "Lama"; the latter would then split again into "Lama" and "Vicugna" upon migrating down to South America.
