The phylogeny is an illustration of the evolutionary history of a group of species through the use of a cladogram. In this illustration, each branch point represents the common ancestor of the two lineages diverging from it. We can basically assume that the more branching points that are shared between species, the more related they are.
Consider the following two cladograms of a portion of theanimal kingdom below. The 2 cladograms represent the same evolutionary pattern; they are just drawn differently.
