On the Origin of Species
First published in 1859, Charles Darwin's book presents the theory of evolution by natural selection. Drawing on observations from his voyage on HMS Beagle, his study of domestic breeding, and years of patient research, Darwin argues that living things vary, that more offspring are born than can survive, and that those with favorable traits are more likely to reproduce. Over long stretches of time, this process can produce new species from common ancestors. Darwin writes carefully and addresses objections directly, building his case from pigeons and barnacles to the geological record. The book reshaped biology and remains one of the most consequential works of science ever written. It was a bestseller in its own time and continues to be read as the foundation of modern evolutionary thought.
