By: Charles Robert Darwin.
Full title: On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life.
Charles Darwin published a book in 1859 to answer the question, “How do living organisms change and adapt?”. The book is a work of scientific literature which is considered to be the foundation of evolutionary biology.
Between 1831 and 1836 Darwin travelled around the world as a naturalist aboard the Beagle. As he observed different species, Darwin was puzzled by tiny adaptive variations in closely related species such as the tortoises, iguanas and finches of the Galapagos Islands. How had these differences arisen? Darwin stumbled upon the solution two years after returning home, after reading Thomas Malthus’ Essay on the Principle of Population (1798).
