| - The cave lion is sometimes considered a species in its own right, under the name Panthera spelaea,[1] and at least one authority, based on a comparison of skull shapes, considers the cave lion to be more closely related to the tiger, which would result in the formal name Panthera tigris spelaea.[2] However, recent genetic research shows it was most closely related to the modern lion among extant felids,[3][4] and that it formed a single population with the Beringian cave lion,[4] which has been sometimes considered as to represent a distinct form. Therefore, the cave lion ranged from Europe to Alaska over the Bering land bridge until the late Pleistocene. However, it is still not clear whether it should be considered a subspecies of the lion or rather a closely related species.[4]

Therefore, the cave lion ranged from Europe to Alaska over the Bering land bridge until the late Pleistocene. However, it is still not clear whether it should be considered a subspecies of the lion or rather a closely related species.[4] Analysis of skulls and mandibles of a lion that inhabited Yakutia (Russia), Alaska (USA), and the Yukon Territory (Canada) during the Pleistocene epoch suggested that it was a new subspecies different from the other prehistoric lions, Panthera leo vereshchagini, known as the East Siberian- or Beringian cave lion[5] It differed from Panthera leo spelaea by its larger size and from the American lion (Panthera leo atrox) by its smaller size and by skull proportions.[5][6] However, recent genetic research, using ancient DNA from Beringian lions found no evidence for separating Panthera leo vereshchagini from the European cave lion; indeed, DNA signatures from lions from Europe and Alaska were indistinguishable, suggesting one large
