Are Phylogenetic Trees the Same as Cladograms?

A cladogram is a diagram which shows the relationship between different organisms based on their different similarities. A phylogenetic tree is a diagram which shows the phylogenetic history of organisms with respect to the geological time scale.

What is the difference between a cladogram and a Phylogram?

A phylogram is a branching diagram (tree) that is assumed to be an estimate of a phylogeny. The branch lengths are proportional to the amount of inferred evolutionary change. A cladogram is a branching diagram (tree) assumed to be an estimate of a phylogeny where the branches are of equal length.

How is phylogeny different from the Linnaean classification system?

In contrast to the traditional Linnaean system of classification, phylogenetic classification names only clades. For example, a strictly Linnaean system of classification might place the birds and the non-Avian dinosaurs into two separate groups. ... Second, phylogenetic classification does not attempt to "rank" organisms.
