摘要：It has been over 50 years since Willi Hennig proposed a new method for determining genealogical relationships among species, which he called phylogenetic systematics.Many people, however, still approach the method warily, worried that they will have to grapple with an overwhelming number of new terms and concepts.In fact, reading and understanding phylogenetic trees is really not difficult at all.You only need to learn three new words, autapomorphy, synapomorphy, and plesiomorphy.All of the other concepts (e.g., ancestors, monophyletic groups, paraphyletic groups) are familiar ones that were already part of Darwinian evolution before Hennig arrived on the scene.
