In the 1830s, Darwin embarked on a five-year circumnavigation on the HMS Beagle (HMS Beagle), collecting and observing a large number of animals, plants and geological structures. In 1859, he published the epoch-making work "The Origin of Species". In this book, Darwin proposed the theory of evolution for the first time, proving that species evolve through natural selection and artificial selection. The theory of evolution was hailed by Engels as one of the three major discoveries in natural science in the 19th century and had a profound impact on later generations. The illustrated version selects the first edition of "The Origin of Species" that is most faithful to Darwin's "theory of evolution" as the mother version. It selects more than a hundred hand-drawn natural history illustrations from Darwin's period and annotates them to faithfully present the prosperity and beauty of natural history in that era.
