Learning that the captain of the ship, the Beagle, wanted someone who would like to have the opportunity of visiting distance countries yet little known, a young man answered the call. Obviously, he was not the captain’s first choice. That was why he had left medical school without completing his degree. In addition to, he had recently received a letter from his father predicting he would be a disgrace to himself and all his family. Despite all this, his adventures on this ship will lead to one of the most important scientific discoveries of all time.
The young man in question was Charles Darwin,a geologist and naturalist, fascinating by rocks, plants and animals. He had his room on the ship crowded with samples of the plants and animals he had collected. Studying these, he wondered what different species came to exist.
After noticing some species of animals were similar to each other, he came up an idea that maybe animals evolved as they adapted to their changing environments.
It was such new an idea that nobody believed him. But they refused to believe that living things, including humans, had evolved from lower form of life.
