Phylogenetic systematics as proposed by Hennig has become very successful. However, since its beginning, it has suffered from a fundamental mistake which appears inconsequential at first glance: the relative concepts of synapomorphy and symplesiomorphy were employed as ifthey were absolute. Closer inspection reveals the full impact of this mistake which has resulted in the exclusion of "symplesiomorphies",
once recognized as such, from further analysis, and to transforming phylogenetic systematics into a form of nonphylogenetic systematics named cladisti9s which is not based in any way on the theory of evolution.
By re-establishing the relativity of the concepts analysed, advanced phylogenetic systematics is achieved in which, by employing the so-called loss tracing method and knowledge ultimately inferred from the theory
of evolution, traditional "symplesiomorphies" become exploitable for recognizing holophyletic species sets. Therefore, advanced phylogenetic systematics is superior to traditional phylogenetic systematics and
cladistics.. A nematological example is provided which demonstrates the new approach.
