The majority view today is that the Eurasian cave lion, the American lion, the extinct S European lions and modern Asian and African lions are all members of a single "chronospecies" (Panthera leo). In an article published in 1996 J. Th. Groiss examined the endocranial features of fossil "lions" and argued that the cave lion as well as an earlier form called P. l. fossilis and possibly American lions were more closely related to tigers and should be classified as subspecies of Panthera tigris. As there are no molecular data available for fossil pantherines, the debate will probably continue for a long time. If the orthodox classification is correct, the range of the lion ca. 12,000 years BP overlapped five continents and was wider than that of any other mammal species (excluding man and domestic or synanthropic animals).Piotr
