On the Origin of Species By Means of Natural Selection / Or, the Preservation of Favoured Races in the Struggle for Life

In 'On the Origin of Species', Charles Darwin presents a groundbreaking theory of evolution through natural selection, detailing how species adapt over time through variation, competition, and environmental influences. Drawing on observations from his voyage on the H.M.S. 'Beagle', Darwin challenges the notion of immutable species, emphasizing the interconnectedness of life and the gradual processes that shape biodiversity. This seminal work lays the foundation for modern evolutionary biology, exploring themes of adaptation, extinction, and the intricate relationships among species.
