The global distribution of Panthera leo, Panthera tigris, and Ursus arctos. The most dominant species would greatly multiply and spread across continents. For each of these great members of the order Carnivora, it takes land measured in square miles for individuals to live. The less the species has spread across the globe, the less successful he was as a dominating species - IMO.

Thank you very much Tom. These maps show from top, the domain of the tiger followed by the domain of the lion and then the brown bear. Of these three dominating predators, the brown bear is the most wide spread.

I will say, the Tigers overall distribution has shrunk considerably in not that long of a period as has the Lion.
Maybe not as drastic, but even the Brown Bear's (Grizzly) current distribution compared to the Historical range has shrunk as well.

The devastation on all three species at the hand of man is heart-breaking. A horrific shame.

Lions of earlier steppe and cave types range in Eurasia is not yet shown.
American lion range has also not been noted here.
Lions dominated massive grassland hunting areas before humans took over.
Tiger and bear as solitary hunters could not compete with social lions.
Social wild dogs also.

WE are discussing three species here: Panthera leo, Panthera tigris, and Ursus arctos. Neither the cave lion nor the American lion belong as they are only distant relatives of modern lions. You say that tiger and bear could not compete with lions or wild dogs, yet the brown bear conquered more territory than did the lion. Panthera spelaea, Panthera atrox, and Panthera leo are three different big cats. <iframe width="13.799999999999955" height="10.060000000000002" style="position: absolute; width: 13.8px; height: 10.06px; z-index: -9999; border-style: none; left: 5px; top: 95px;" id="MoatPxIOPT0_97575913" scrolling="no"></iframe> <iframe width="13.799999999999955" height="10.060000000000002" style="position: absolute; width: 13.8px; height: 10.06px; z-index: -9999; border-style: none; left: 630px; top: 95px;" id="MoatPxIOPT0_94732392" scrolling="no"></iframe> <iframe width="13.799999999999955" height="10.060000000000002" style="position: absolute; width: 13.8px; height: 10.06px; z-index: -9999; border-style: none; left: 5px; top: 536px;" id="MoatPxIOPT0_98235344" scrolling="no"></iframe> <iframe width="13.799999999999955" height="10.060000000000002" style="position: absolute; width: 13.8px; height: 10.06px; z-index: -9999; border-style: none; left: 630px; top: 536px;" id="MoatPxIOPT0_72059329" scrolling="no"></iframe>

When there was more land - Sundaland in Southeast Asia.

atlantisjavasea.com/2015/09/29/sundaland/ Sundaland is a bio-geographical region of Southeastern Asia which encompasses the Sunda shelf, the part of the Asian continental shelf that was exposed during the last Ice Age. The last glacial period, popularly known as the Ice Age, was the most recent glacial period within the current Ice Age occurring during the last years of the Pleistocene, from approximately 110,000 to 12,000 years ago. It included the Malay Peninsula on the Asian mainland, as well as the large islands of Kalimantan, Java, and Sumatera and their surrounding islands. The eastern boundary of Sundaland is the Wallace Line, identified by Alfred Russel Wallace as the eastern boundary of the range of Asia’s land mammal fauna, and thus the boundary of the Indomalaya and Australasia ecozones. The islands east of the Wallace line are known as Wallacea, and are considered part of Australasia. It is worth noting that it is now generally accepted that South East Asia was probably the entry point of modern humans from Africa. The name “Sundaland” was first proposed by van Bemmelen in 1949, followed by Katili (1975), Hamilton (1979) and Hutchison (1989), to describe the continental core of Southeast Asia forming the southern part of the Eurasian plate. Sundaland is bordered to the west, south and east by tectonically active region characterized by intense seismicity and volcanic activity. The tectonically active zone is effectively a mountain belt in the process of formation, and contain many of the features typically thought to be associated with accretionary orogens: there is active subduction, transfer of material at plate boundaries, examples of collision with buoyant feature on oceanic plates, arcs and continents, and abundant magmatism. The present orogenic belt is situated at the junction of three major plates: the Eurasian, Indian, Australian and Pacific-Philippine Sea plates. It surrounds Sundaland and stretches from Sumatera to The Philippines via eastern Indonesia. It changes character and width from west to east and is composed of different segments or sutures with different character. Note: more reading and more maps on site.

Lions of earlier steppe and cave types range in Eurasia is not yet shown. American lion range has also not been noted here. Lions dominated massive grassland hunting areas before humans took over. Tiger and bear as solitary hunters could not compete with social lions. Social wild dogs also. The cave lions could not kill a big male cave bear . Grizzly bears and even tigers are able to displace social wolf packs. Large crocodiles and even large brown bears and polar bears are able to displace small lion prides. Cave lions are probably not as socialble as African lions.

Reply #2 ... Lion Distribution... is about Panthera leo... not cave lions or American lions which were other species. As a species; neither the lion ( P. leo ) nor the tiger ( P. tigris ) were as successful as U. arctos in the matter of populating land. See maps on reply #2 - Ursus arctos is far more successful in conquering new lands than is Panthera leo or Panthera tigris.
