Chapter 16, Problem 3SQ
Summary Introduction
Introduction: Evolution is a very slow process that occurs gradually. Evolution is a process where the change occurs in the living things over the time period that is successfully inherited and passed to future generations. At every level of organization of living beings, the evolution leads to biodiversity.
