On September 15, 1835, the ship HMS Beagle with the young naturalist Charles Darwin on board reached the Galapagos Islands. For over five weeks Darwin made observations on the geology and biology of the four islands, leading to major scientific discoveries, including the explanation of how volcanic tuff is formed.

Darwin’s observations of birds that differed between the islands were significant for the development of his theory of natural selection, which he later expanded in his On the Origin of Species.

The journal he kept throughout the journey was published in 1839. The book became an important point of reference not only for the scientific world, but also for anthropologists, because of Darwin’s detailed description of the local populations, their livelihood and their customs.

The second edition of the book published in 1845 is particularly interesting, because there he put together his theory of natural selection, which was only at the stage of conception in the first edition.
