The Origins of Species

"On the Origin of Species," by Charles Darwin, explains how species evolve over time through a process called natural selection. Organisms produce more offspring than can survive, and those with traits better suited to their environment are more likely to thrive and reproduce. Over generations, this leads to gradual changes and the development of new species. Darwin's ideas showed that all living beings are connected through shared ancestors, emphasizing evolution as a natural, ongoing process driven by variation, competition, and survival. The book fundamentally changed our understanding of life’s diversity and adaptation.
