Charles Darwin was an English scientist, best known for his theory on the evolution of species.
Charles Darwin was a naturalist and geologist who had the opportunity to sail around the world aboard the HMS Beagle to map the areas they sailed past. On these trips, he would also study the wildlife and plants he encountered. Based on the findings, he started to believe in common ancestors among species and natural selection. These theories would be written in his books, among which The Voyage of the Beagle and On the Origin of Species are the best known ones.
