The number of accepted species in Felidae has been around 40 since the 18th century, though research, especially modern molecular phylogenetic analysis, has over time adjusted the generally accepted genera as well as the divisions between recognized subspecies, species, and population groups. [9]
Most cat species have a haploid number of 18 or 19. Central and South American cats have a haploid number of 18, possibly due to the combination of two smaller chromosomes into a larger one. [31] Felidae have type IIx muscle fibers three times more powerful than the muscle fibers of human athletes. [32]
Felidae (/ ˈ f ɛ l ɪ d iː /) is the family of mammals in the order Carnivora colloquially referred to as cats. A member of this family is also called a felid ( / ˈ f iː l ɪ d / ). The 41 extant Felidae species exhibit the greatest diversity in fur patterns of all terrestrial carnivores.
Criteria: Articles on subfamilies, genera, species, and subspecies in the family Felidae that are known only from fossils. Subcategories This category has the following 4 subcategories, out of 4 total.
The small cats or Felinae are a subfamily of Felidae distinguished by their bony hyoids, which let them purr but not roar. [2] Other authors have proposed an alternative definition for this subfamily, as comprising only the living conical-toothed cat genera with two tribes, the Felini and Pantherini, and excluding the extinct sabre-toothed Machairodontinae.
15] [16] Analysis of mitochondrial DNA of all Felidae species indicates a radiation at around [ 17 ] The European wildcat is part of an evolutionary lineage that is estimated to have genetically diverged from the common ancestor of the Felis species around 1.62 to 0.59 million years ago , based on analysis of their nuclear DNA.
Phylogenetic analysis of the nuclear DNA in tissue samples from all Felidae species revealed that the evolutionary radiation of the Felidae began in Asia in the Miocene around 4] Analysis of mitochondrial DNA of all Felidae species indicates a radiation at around 16.76 to 6.46 million years ago .
A taxon above the rank of species has a scientific name in one part (a uninominal name). A species has a name typically composed of two parts (a binomial name or binomen): generic name + specific name; for example Canis lupus. Sometimes the name of a subgenus (in parentheses) can be intercalated between the genus name and the specific epithet ...
