Answer:
In 1831, Charles Darwin received an invitation to join the HMS Beagle as the 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. When 22-year-old Darwin set sail, he was a young university graduate, still planning a career as a clergyman. By the time he returned however, he was an established naturalist, well-known for the astonishing collections he'd sent ahead. He'd also grown from an observer of science into a probing theorist, and the voyage would provide him with a lifetime of experiences to ponder, and the seeds of a theory he would work on for the rest of his life.
Hope this is okay and helps!
