29 wrz 2010 · Phylogenetic trees are reconstructed by a method called “phylogenetic systematics” (Fig. 3). This method clusters groups of organisms together based upon shared, unique characters called synapomorphies. For example, you share the presence of a backbone with cats, but not with butterflies.
