Charles DarwinCharles Robert Darwin(12 February 1809 – 19 April 1882) was anEnglish naturalist, geologist and biologistbest known for his contributions to thescience of evolution. His proposition that allspecies of life have descended over timefrom common ancestors is now widelyaccepted, and considered a foundationalconcept in science.
In 1831, Charles Darwin received an astounding invitation: to join the HMS Beagle as ship's naturalist for a trip around the world. For most of the next five years, the Beagle surveyed the coast of South America, leaving Darwin free to explore the continent and islands, including the Galápagos. He filled dozens of notebooks with careful observations on animals, plants and geology, and collected thousands of specimens, which he crated and sent home for further study.He was thenaturaliston the Darwin on the HMS Beagle
