Temporal range: Upper Oligocene – Recent
|Tiger, the largest feline found in nature.|
G. Fischer de Waldheim, 1817
Felidae is a family of mammals, in the order Carnivora. Animals that belong to Felidae are called felines. The family is of quite recent origin: the first fossils are from the Oligocene, 25 million years ago (mya). There are 41 living species, including the domestic cat, and they are monophyletic: all descended from the same ancestor.
The Felidae has three subfamilies:
- †Machairodontinae: sabre-toothed cats.
- Pantherinae: large cats tiger, lion, jaguar, leopard
- Felinae: cougar, cheetah and smaller cats
More examples of felines are the big cats – the lion, tiger, leopard, jaguar, snow leopard, clouded leopard, puma, and cheetah - and other wild cats, for example the lynx, caracal, and bobcat. All felines, also the small pet cat, are predators that can hunt many animals.
Evolution[change | edit source]
The felids evolved in Asia and spread across continents by crossing land bridges. DNA sequence analysis shows that ancient cats evolved into eight main lines. There were at least 10 migrations (in both directions) from continent to continent via the Bering land bridge and Isthmus of Panama. The Panthera genus is the oldest and the Felis genus is the youngest. 60 percent of the modern species of cats developed within the last million years.
The felids' closest relatives are the linsangs, and at one remove the group of civets, hyenas, mongooses, and Madagascar carnivores, with whom they share the Suborder Feliformia. All felid species share a genetic anomaly that prevents them from tasting sweetness.
Genetic classification[change | edit source]
Genetic research has provided a basis for a more concise classification for the living members of the cat family based on genotypical groupings. Specifically, eight genetic lineages have been identified:
- Lineage 1: Panthera, Uncia, Neofelis
- Lineage 2: Pardofelis, Catopuma
- Lineage 3: Leptailurus, Caracal, Profelis
- Lineage 4: Leopardus
- Lineage 5: Lynx
- Lineage 6: Puma, Acinonyx
- Lineage 7: Prionailurus, Otocolobus
- Lineage 8: Felis
