The groundbreaking work presents Darwin's theory of evolution through natural selection, detailing how species adapt and evolve over time. It challenges traditional views of creation, providing evidence from various fields such as biology, geology, and paleontology. Key concepts include the struggle for existence, survival of the fittest, and the gradual changes in species. This seminal text laid the foundation for modern biology and continues to influence scientific thought and debate on the origins of life.
