Mutation theory, also known as the theory of genetic variability or genetic mutation, is an essential concept in biology. This theory states that genetic variations occur through random changes in the DNA sequence of organisms. There are several synonyms used for mutation theory, including Evolution Theory, Darwinism, Molecular biology, and Genetic mutation. Darwinism refers to the scientific theory of Charles Darwin that emphasizes the concept of natural selection and the survival of the fittest. Molecular Biology deals with the study of the molecular basis of biological activity, including genes and their products. Genetic mutation refers to the spontaneous changes in the DNA sequence that can lead to genetic disorders and new traits. These synonyms can be used interchangeably to describe the concept of mutation theory and their respective areas of focus in biology.
