He collected evidence for his theory for 8 years.
From 1831 to 1836, Charles Darwin traveled the world in the HMS Beagle as a naturalist. His findings and experiences aided him in formulating the theory of evolution by natural selection.
Darwin was fortunate to travel to the Galapagos Islands on the Beagle, where he saw a variety of creatures and birds that had developed in a solitary setting. His discoveries inspired him to develop his well-known natural selection theory. Darwin's hypothesis states that differences within species happen at random and that an organism's capacity to adapt to its environment determines whether it will survive or become extinct.
Important observations regarding the geology of the islands and coasts that Darwin visited are also noteworthy. He put forth a notion regarding how atolls are formed. Small islands made of coral reefs called atolls surround lagoons. Most of them may be found in the Pacific. Bikini Atoll, which is northwest of Hawaii, is one example.
