Summary Introduction

To write:

If, all features of living organism arise from adoption and, if a trait in an organism is a product of natural selection by evolution.

Introduction:

Evolution may occur through several mechanisms like genetic drift, mutations and migration. In natural selection, the fittest organism is selected naturally. Natural selection is a process which results in adaptations of an organism to its environment through means of a selective reproduction of the changes in their genetic constitution or genotype. Natural selection is the key mechanism of evolution, which is the change in inherited traits or characteristics of a population over the generations. Adaptations are the changes or modifications in the body of the organism or behavior which aid in survival.
