The brown bear Kurten believed to be "clearly derived from the Asian population of Ursus savini about 800,000 years ago; spread into Europe, to the New World." Ursus ingressus was likely better adapted to continental environments and, thus, might have outperformed U. spelaeus during cold and arid climate conditions (Baryshnikov and Puzachenko, 2011). No doubt it took the bear many millennia to wander through what is now Alaska into the coastal ranges of the Northwest, to the Sierra Nevada, to the Rockies, to the parched hills of Mexico. Polar bears were summarised by Kurten (1964) from an evolutionary context. This species appears to be the most primitive living species of the genus Ursus, as it usually retains a full complement of premolars. Speciation occurred during a time when climatic fluctuations caused periodically extensive glaciation in northern con- tinental areas. Taxonomy research has shown that the Brown Bear is most closely related to the Polar Bear (Ursus Maritimus).
