The new term biogenetic convergence ruleis suggested as a replacement for Haeckels old term biogenetic law. It works as follows: by converging on identical adult structures, polarizations of phylogenetic transformation series are determined by those of corresponding ontogenetic transformation series. Examples from nematology are presented. Cases of paedomorphosis are subject to asecond rule suggested as the biogenetic suppression rule. Athirdrule, suggested as the adaptive convergence rule, refers to well-known cases in which adaptions to particular environmental conditions result in the similarity of otherwise different structures. Essential findings of chaos science are outlined and illustrated by Waddingtons epigenetic landscape in order to show that the biogenetic convergence rule fits to these new findings. Contrary to common belief, the popular outgroup algorithm reveals to be unsuitable for polarizing sequences of character states. For theoretical reasons, Hennigs unsupported demand is rejectedto accept only holophyletic taxa as valid. Paraphyletic taxa must also be accepted as valid.Therefore, phylogenetic systematics sensu Hennig and evolutionary systematics sensu Mayr aresuggested as synonyms.
