Die kambrische Explosion

The Cambrian explosion

Abstract

This article reviews events during the Proterozoic/ Cambrian turnover, termed the “Cambrian explosion”. The first part heralds observed stages of the organismal evolution and discusses their influence and bearing on the latest concept of the Proterozoic/Cambrian boundary. In addition, the number and extent of Cambrian fossil lagerstaetten and their meaning for the interpretation of Metazoan diversification is discussed. A third part gives a synoptic overview of the most important proposed causes and mechanisms for the Cambrian explosion.

Kurzfassung

Der vorliegende Artikel faßt die Ereignisse an der Wende Proterozoikum/Kambrium zusammen, die als «kambrische Explosion» bezeichnet wurden. Zunächst werden die beobachteten Etappen der organismischen Evolution vorgestellt und ihr Einfluß auf das heutige Konzept der Grenze Proterozoikum/Kambrium diskutiert. Anschließend wird das Ausmaß der kambrischen Fossilarchive und ihre Bedeutung für die heutige Sicht der Metazoen-Entfaltung referiert. Schließlich wird versucht, eine Übersicht über die wichtigsten der vielen diskutierten Ursachen und Mechanismen der kambrischen Explosion zu geben.
