Journal of Researches into the Natural History and Geology of the Countries Visited during the Voyage of HMS Beagle round the World, under the Command of Capt. Fitz Roy, R.N.

Charles Darwin (1809–82) was the English naturalist famous for the theory of evolution by natural selection. He began studying medicine at the University of Edinburgh, but developed a fascination for natural history and left Edinburgh to attend Christ's College, Cambridge, where he pursued his new interest while taking a Bachelor of Arts degree. After graduating, he had the opportunity to secure a position as ship's naturalist aboard H.M.S. Beagle for a five-year, round-the-world voyage which would make him famous. Published in 1845, this book is the second edition of Darwin's expedition journal, more popularly known as The Voyage of the Beagle. Throughout the journey he made observations and discoveries that would lead him to develop his revolutionary theory of evolution, which later appeared in On the Origin of Species and created a storm in the scientific and religious communities.
