Chapter 32, Problem 3TYU
Summary Introduction
Introduction: Cambrian explosion lead to the sudden diversification of the amimal species. Cambrian explosion actually consist of the three explosion in which several morphological (novel adaptations in prey predator), geological (increase in oxygen level) and genetic mutations and duplications occurred (Hox genes).
