Based on Simpson, these groupings were not monophyletic, that means that they did not signify a single, whole department of the tree of life; that is, an ancestor and all of its descendants. At the moment's classification has shifted away from a system constructed on morphology to 1 primarily based on genetic similarities and variations. The result is a family tree of types, mapping out evolutionary relationships between numerous organisms.
