Research overview: the eight lineages of living cats

Molecular phylogenetics partitions all living cats into eight monophyletic lineages, a framework that now organizes felid taxonomy. This overview names and characterizes them: the Panthera lineage (big cats and clouded leopards), the bay cat lineage, the caracal lineage, the ocelot lineage, the lynx lineage, the puma lineage, the leopard cat lineage, and the domestic cat lineage. For each it summarizes the included genera and species, approximate divergence times, and biogeographic origin. The piece explains how these lineages dispersed across continents via land bridges during low sea-level periods, producing today's distributions. It emphasizes that the lineage framework is highly stable even where species and genus boundaries remain debated, giving enthusiasts a durable mental map of feline diversity.
