Concept

Problem: How is the term Cambrian explosion misleading?Distinguish between convergent evolution and divergent evolution. Which type of selection would you expect to be the major factor in convergent evolution? In divergent evolution? Why are mutations important in evolution? Natural selection can lead to the evolution of prezygotic isolating mechanisms, but not post-zygotic isolating mechanisms? Explain.

The term explosion can be misleading because explosion means destruction, but instead Cambrian Explosion give rise to a massive diversity of life and marked as on of the major period of evolution.
