Feliformia is a suborder within the order Carnivora consisting of "cat-like" carnivorans, including cats (large and small), hyenas, mongooses, viverrids, and related taxa. Feliformia stands in contrast to the other suborder of Carnivora, Caniformia consisting of "dog-like" carnivorans (includes Canoidea).
The project of a complete description of the phylogenetic relationships among all biological species is dubbed the "tree of life". This involves inference of ages of divergence for all hypothesized clades; for example, the MRCA of all Carnivora (cats, dogs, etc.) is estimated to have diverged some 42 million years ago . [6]
The Open Tree of Life is an online phylogenetic tree of life – a collaborative effort, funded by the National Science Foundation. [2] [3] The first draft, including 2.3 million species, was released in September 2015. [4] The Interactive graph allows the user to zoom in to taxonomic classifications, phylogenetic trees, and information about a ...
TreeFam (Tree families database) is a database of phylogenetic trees of animal genes.It aims at developing a curated resource that gives reliable information about ortholog and paralog assignments, and evolutionary history of various gene families.
Caniformia is a suborder within the order Carnivora consisting of "dog-like" carnivorans. They include dogs (wolves, foxes, etc.), bears, raccoons, and mustelids. [1] The Pinnipedia (seals, walruses and sea lions) are also assigned to this group. The center of diversification for the Caniformia is North America and northern Eurasia.
A free computational phylogenetics package of programs for inferring evolutionary trees (phylogenies). One such example tree created by PHYLIP, called a "drawgram", generates rooted trees. This image shown in the figure below shows the evolution of phylogenetic trees over time. 1981 Majority consensus, Margush and MacMorris. [62]
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).
The trees also helped show that F. s. lybica gave rise to the domesticated cats of today. F. s. silvestris showed a very early branching away from the other groups, but still shares a very early common ancestor with the rest of the clades. [5] Domesticated cats originated [11] from near-eastern and Egyptian populations of F. s. lybica. The ...
