Research overview: the snow leopard and the base of the Panthera tree

This overview surveys the evolutionary placement of the snow leopard within the big-cat genus Panthera and its relevance to fossil studies. Once isolated in its own genus, the snow leopard is now firmly nested within Panthera, and several analyses place it near the base of the lineage or close to the tiger, though its exact position has shifted with different datasets. The survey reviews how molecular phylogenies and fossils such as the early pantherine Panthera blytheae, interpreted as snow-leopard-like, bear on this question, and what the snow leopard's high-altitude Central Asian distribution implies for theories of a Tibetan origin of big cats. It discusses why resolving the snow leopard's branch matters for reconstructing the earliest stages of Panthera evolution and the deep history of the great cats.
