Concept explainers
To determine: Whether the morphological diversity of animals has increased, decreased, or remained the same since the Cambrian.
Introduction: Paleozoic era started with the Cambrian period. Initially, animal diversity was low in the Cambrian period. The interval of the first 20 million year of the Cambrian era saw an explosion of diversity in animals. During this interval, other classes of echinoderms, arthropods, and mollusks first appeared. This period is known as Cambrian explosion because morphological diversity of animals exploded in very less time.
To explain: The bias dictating the analysis of whether the morphological diversity of animals has increased, decreased, or remained the same since the Cambrian
