Chapter 23.2, Problem 2CC
Summary Introduction
To summarize:
The way in which the mass extinction affect the evolutionary history of life.
Introduction:
Mass extinction is the extinction or the loss of many organisms at one time. All the species are interrelated with one another. They directly or indirectly lead to the ecological balance. Extinction of any of the species will lead to ecological imbalance.
