The evolution of Felids (or Felidae), the family of mammals to which cats (domestic and wild) also belong, has been studied by scientists for more than 200 years. In this article we will offer you an overview of the history of the Felidae family and the subsequent lower classifications of its subgroups, Felinae and Pantherinae.
History and evolution
The study of fossils makes scientists argue that Felidae (Felidae) did originated between the end of the Eocene and the beginning of the Oligocene (33.9-23 million years ago): in fact, the traces of the first ever documented Felide, the Proailurus, can be dated to this period. It was about the size of a bobcat, with an elongated body (including skull and tail) but short legs and primitive teeth that had more molars and premolars than modern felids.
Reconstruction of the possible appearance of a Proailurus
It has been speculated that some specimens of Proailurus they migrated to North America evolving into Pseudaelurus dating back to the Miocene, and more precisely between 20 and 9 million years ago. It was found in both America that in Europe, where it has been distinguished into 5 and 4 different species respectively. The size of the Pseudaelurus ranged from that of a modern wild cat to that of a small puma; however it still had primitive characteristics, such as the low and long body and the teeth similar to those of the Proailurus. It is from him that the saber-toothed tigers are thought to have originated, whose lineage became extinct about 10,000 years ago.
Then the genus dates back to the upper Miocene (about 8 million years ago) Styriofelis, object of lively debates and repeated reviews by the scientific community, initially more inclined to consider it part of Pseudaelurus or Felis. A consensus has now been reached on the fact that it is a genus in its own right, connected moreover to modern cats since it has a teeth more similar to theirs.
It is the kind though Pristifelis (and more precisely the P. attica species), dating back to the end of the Miocene, the closest to the cats we know. Equipped with a build similar to an African golden cat or a Serval, he was the size of a bobcat but with a more elongated profile. To distinguish it from the genera described above is the reduced dentition, which allows to develop a shorter muzzle and more similar to today's cat.
A clouded leopard.
About 10.8 million years ago the separation from this line by the genus occurred Panthera, which today includes lions, tigers, leopards, snow leopards, clouded leopards and Borneo clouded leopards. 9.4 million years ago it was the turn of the genus Pardofelis which includes the bay cat, the Asian golden cat and the marbled cat. The Caracal line, which includes the caracal, the serval, and the African golden cat, separated 8.5 million years ago, followed by the genus Leopardus which includes most of the small South American cats and from the genus Lynx (7, 2 Ma).
To the line named Puma belong to the genus of the same name and the Acinonix; these include puma, cheetah and yaguarondi (also called eyra). At 6.2 million years ago there was finally the distinction between two other lines: the first in the genera Otocolobus (Pallas's cat) e Prionailurus (viverrino cat or fisherman cat), the second in the genus Felis (domestic cat).
Subsequent lower rankings
Two living subfamilies belong to the Felidae family, with their relative genera and species. Here are the later lower rankings:
The Felinae phytogenic tree, lower classification of the Felidae family.
The felines or Felinae they are a subfamily of the Felidae family. They are characterized by the presence of a rounded head, short muzzle and a body covered with fur, often spotted or streaked. They have padded legs and claws that they use for hunting, and they have excellent hearing and sight, which gives them the ability to hunt at night. Here are the genres and the lower ratings by Felidae:

According to legend, many centuries ago, in Burma (Birmanie in French, which explains the name of this breed), there was the Lao-Tsun temple where the priests of Kittah worshiped the beautiful goddess Tsun Kyan Kse of the Khmer people. This deity had a golden body and sapphire blue eyes and ruled the passage of souls.
