A Sphynx cat, one of the cat breeds resulting from human breeding practices during the last century and a half. In 1871 only five cat breeds were recognized by an association in London. Today the USA based Cat Fanciers Association (CFA) recognizes 41 breeds [20] and The International Cat Association (TICA) recognizes 57 breeds. [21]

Homotherini (Machairodontini) is a tribe (or subtribe) [1] of saber-toothed cats of the family Felidae (true cats). The tribe is commonly known as scimitar-toothed cats.These saber-toothed cats were endemic to North America, Europe, Asia, Africa, and South America [2] from the Miocene to Pleistocene living from c. 23 Ma until c. 12,000 years ago.

Common descent is a concept in evolutionary biology applicable when one species is the ancestor of two or more species later in time. According to modern evolutionary biology, all living beings could be descendants of a unique ancestor commonly referred to as the last universal common ancestor (LUCA) of all life on Earth.

The term "big cat" is typically used to refer to any of the five living members of the genus Panthera, namely the tiger, lion, jaguar, leopard, and snow leopard. [ 1 ] [ 2 ] All cats descend from the Felidae family, sharing similar musculature, cardiovascular systems, skeletal frames, and behaviour.
The idea of a tree of life arose from ancient notions of a ladder-like progression from lower into higher forms of life (such as in the Great Chain of Being).Early representations of "branching" phylogenetic trees include a "paleontological chart" showing the geological relationships among plants and animals in the book Elementary Geology, by Edward Hitchcock (first edition: 1840).
A cat named Creme Puff is considered to be the oldest cat ever with a lifespan of 38 years and 3 days. We’ve compiled a list of the 10 oldest cats by accepting the owner’s word as reported in ...
The fact that small cats have an ERV where the larger cats do not suggests that the gene was inserted into the ancestor of the small cats after the larger cats had diverged. [35] Another example of this is with humans and chimps. Humans contain numerous ERVs that comprise a considerable percentage of the genome.
