The Langarans are a race of humans living on the planet Langara. Jonas Quinn is one of the most notable of these people, having become a member of SG-1 for one year. Jonas has a physiology which permits him to be a quick study and retain information like one with a photographic memory. He also has other physiological differences which gained the interest of Nirrti and Anubis both. It is not clear if these advances in physiology were specific to Jonas alone or if they were shared by others of his nation Kelowna or of his home planet. In Season Seven, the planet was renamed Langara in an attempt to recognize the uniting of the three major nations of the world: Kelowna, Andari, and Terania.
