Summary Introduction
Introduction: In the field of biology, a theory is simply defined as a broad description of a phenomenon that is occurring in nature. Most of the scientists consider a theory as an accepted fact. However, it has been observed in some cases that a theory may be wrong as well. Theories can result in a hypothesis.
