Summary Introduction

To review

The way in which different breeds of dogs with distinct characteristics were evolved even when they belong to the same species and capable of interbreeding.

Introduction:

Evolution explains the diversity of life on Earth. Evolution is defined as an unpredictable and natural process of descent over time with genetic modification. An important aspect of the evolutionary theory is natural selection. Natural selection means that individuals with certain traits are better suited to their local environment compared to other individuals who lack those traits. Therefore, the former is more likely than the latter to survive and reproduce.
