5. VIII. Phylogeny & Classification  Phylogeny—study of the evolutionary history of a species or a group of species  Phylogenetic Tree—branching diagram representing the evolutionary history of a group of organisms  Use a variety of evidence  Sometimes length of branches correlate with time or amount of differences in DNA sequences—If these variables are not mentioned, there is no significance to the lengths of branches
