Research overview: the two-subfamily structure of the Felidae (Pantherinae and Felinae)

Modern classifications divide living cats into two subfamilies: Pantherinae (the roaring and big cats plus clouded leopards) and Felinae (most small and medium cats). This overview explains how that split is supported by molecular phylogenies, divergence-time estimates near the late Miocene, and morphological features such as the incompletely ossified hyoid apparatus in roaring Panthera. It traces how earlier schemes scattered cats across many genera (Felis as a catch-all), and how molecular work consolidated them into eight well-supported lineages nested within the two subfamilies. The piece also notes ongoing debates about where ambiguous taxa, such as the marbled cat and clouded leopards, attach to the tree, and why subfamily-level stability still leaves genus and species boundaries contested.
