Charles Darwin’s voyage on the HMS Beagle was a five-year journey around the world, beginning in 1831. During the voyage, Darwin visited South America, the Galápagos Islands, Australia, and many other places. During these visits, Darwin collected specimens and made observations of the natural world. His observations and collections provided the basis for his theory of evolution by natural selection, which he published in 1859 in On the Origin of Species. The voyage had a profound impact on Darwin’s career, laying the groundwork for his later work as one of the most influential naturalists in history.
