The Origin of Species is a seminal work by the renowned naturalist Charles Darwin. Published in 1859, this book presents Darwin's theory of evolution and natural selection, which revolutionized the field of biology and challenged traditional religious beliefs about the origins of life. In it, Darwin argues that all species of organisms have evolved over time through a process of natural selection, where those individuals with advantageous traits are more likely to survive and reproduce. The book is divided into multiple chapters, each exploring different aspects of evolution, such as the struggle for existence, variation and selection, and the geological record. Darwin also addresses common objections to his theory and provides evidence from diverse fields such as geology, botany, and animal behavior. This edition of The Origin of Species is part of the Harvard Classics series, which includes other important works of literature, philosophy, and science.1909.
