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).
Using Caminalcules to practice the construction of phylogenetic trees has an advantage over using data sets consisting of real organisms, because it prevents the students’ pre-existing knowledge about the classification of real organisms to influence their reasoning during the exercise. [7]
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).
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.
[15] Darwin's tree is not a tree of life, but rather a small portion created to show the principle of evolution. Because it shows relationships (phylogeny) and time (generations), it is a timetree. In contrast, Ernst Haeckel illustrated a phylogenetic tree (branching only) in 1866, not scaled to time, and of real species and higher taxa. In his ...
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 ...

The results are a phylogenetic tree—a diagram depicting the hypothetical relationships between organisms and their evolutionary history. [4] The tips of a phylogenetic tree can be living taxa or fossils, which represent the present time or "end" of an evolutionary lineage, respectively. A phylogenetic diagram can be rooted or unrooted.
