Detailed explanation-1: -In 1831, when Darwin was just 22 years old, he set sail on a scientific expedition on a ship called the HMS Beagle. He was the naturalist on the voyage. As a naturalist, it was his job to observe and collect specimens of plants, animals, rocks, and fossils wherever the expedition went ashore.
Detailed explanation-2: -What was Darwin’s role on the Beagle? He was the naturalist on the voyage, he explored nature for 3 years. What was significant about the new habitats Darwin visited? He saw many different types of plants/rocks.
Detailed explanation-3: -Fitzroy commanded the Beagle’s second voyage (1831–36), with Darwin as naturalist. For this commission, which would involve a circumnavigation of South America and then the globe, the ship underwent a major refit.
Detailed explanation-4: -Darwin noticed that the plants and animals on the different islands also differed. For example, the giant tortoises on one island had saddle-shaped shells, while those on another island had dome-shaped shells (see Figure below). People who lived on the islands could even tell the island a turtle came from by its shell.
Detailed explanation-5: -Darwin was also fortunate that the Beagle took him to the Galapagos Islands, where he observed various animals and birds that had evolved in an isolated environment. His observations led him to his famous theory of natural selection.
