Abstract

Die Systematik entstand zugleich mit der Wissenschaft Biologie und war die Grundlage der Evolutionstheorie. Nachdem Darwin in der natürlichen Zuchtwahl (Selektion) eine naturwissenschaftliche Brgündung für die Evolution gefunden hatte, wurde die Systematik auch zu einer Geschichtswissenschaft, zur Stammesgeschichte. Einen Höhepunkt erreicht die Systematik in Hennigs Theorie der phylogenetischen Systematik. Man hat versucht, Hennigs Ideen zu formalisieren und die Widersprüche zu minimieren. Das hat zur Einbeziehung mathematisch-statistischer Überlegungen in die Rekonstruktion von Stammbäumen geführt. Die heute mögliche Analyse der genetischen Schrift liefert Grundlagen für eine weitgehend exakte Rekonstruktion der Phylogenese
