On the Origin of Species by Means of Natural Selection, or The Preservation of Favoured Races in the Struggle for Life.

The book presents a groundbreaking theory in evolutionary biology, arguing that the diversity of life results from a branching pattern of evolution and common descent. Drawing on extensive evidence gathered during his voyage on the Beagle and subsequent research, Darwin explores the mechanisms of natural selection and the survival of favored races in the struggle for life. This seminal work has profoundly influenced scientific thought and remains a cornerstone of biological understanding.
