nce of his findings while on the voyage, because he lacked the necessary training in dissection and drawing as well as the knowledge of comparative anatomy. It was only much later when Darwin returned from the voyage, and when the fossils were identified by Owen, that Darwin began to examine them as zoological, rather then geological, phenomena.The voyage turned out to be very productive for Darwin, who upon his return in 1836 began to work on the conversion of the diary, which he kept during the voyage, into a journal suitable for publication. The Journal was first published in 1839 under the title "Journal and Remarks", as Volume III of the Narrative of the Surveying Voyages of H.M.S. Adventures and Beagle. However, enough people thought that Darwin's work was sufficiently important to warrant a separate publication, and in 1845 a second edition was published under the name Journal of Research into the Natural History and Geology of the Countries Visited during the Voyage of H.M.S. Beagle Round the World (henceforth referred to as the Journal). It appears to be that only sometime in 1837 did Darwin first start to entertain the idea of evolution seriously. The proof for this lies in the notebook which he kept from July 1837 to February 1838. In particular, the following statement from the notebook provides valuable insight: "In July opened first notebook on transmutation of species. Had been greatly struck from about the previous March on character of South American fossils, and species of Galapagos Archipelago. These facts (especially latter), origin of all my views". Therefore, it must have been at this time that Darwin's ideas took this turn. Furthermore, had the change occurred earlier, it would have shown up in Darwin's writings in the Journal, which, more than half-completed by March, shows no trace of it. Overall, with the notable exception of the idea of natural selection, most of what Darwin later wrote in On the Origin of Sp...
