Japan's ancient 'tigers' were actually cave lions, DNA evidence shows

There aren't any native lion or tiger populations living in Japan today, but this was not always the case. Fossil evidence indicates that at least one species of large cat roamed the archipelago during the Late Pleistocene—a period lasting from approximately 129,000 to 11,700 years ago. While researchers initially thought the fossils came from ancient tigers, new DNA evidence, published in the Proceedings of the National Academy of Sciences, indicates that the fossils actually came from an ancient species of lion.
