Phylogeny is the study of the relationship among items (organisms, concepts, etc); typically, phylogeny is used to study evolutionary relationships represented by trees which can be either a phylogram, which describes variations in "character mutation rate" across a tree, or dendrograms, where the character mutation rate is uniform (a molecular clock).
