This book divides its subject matter into five chapters: "EMERGENCE OF EVOLUTIONARY THOUGHTS", "ORIGIN OF CELLS & UNICELLULAR EVOLUTION", "MECHANISM OF EVOLUTION", "PALEONTOLOGY" and "MOLECULAR EVOLUTION". From the origins of evolutionary theories to the most recent developments in molecular evolution, the chapters provide a thorough overview of evolutionary biology. Every chapter explores important facets of evolutionary theory, such as how early life formed, the mechanisms underlying evolutionary change, the fossil record and genetics. From the historical foundations of evolution to its contemporary applications in disciplines like genetics and paleontology, this framework enables readers to obtain a comprehensive grasp of the subject. It makes use of simple language, diagrammatic drawings that are effective and a tabular layout.
