Description

Cougars are the largest of the small cats. They are placed in the subfamily Felinae, although their bulk characteristics are similar to those of the big cats in the subfamily Pantherinae. The family Felidae is believed to have originated in Asia about 11 million years ago. Taxonomic research on felids remains partial, and much of what is known about their evolutionary history is based on mitochondrial DNA analysis, as cats are poorly represented in the fossil record, and significant confidence intervals exist with suggested dates. In the latest genomic study of the Felidae, the common ancestor of today's Leopardus, Lynx, Puma, Prionailurus, and Felis lineages migrated across the Bering land bridge into the Americas 8.0 to 8.5 million years ago (Mya). The lineages subsequently diverged in that order. North American felids then invaded South America 2–4 Mya as part of the Great American Interchange, following formation of the Isthmus of Panama (Wikipedia).
