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. Therefore, cladograms show common ancestry, but do not indicate the amount of evolutionary “time” separating taxa. It is possible to see the tree distances by clicking on the diagram to get a menu of options. The options available allow you to do things like changing the colours of lines and fonts and showing the distances.
