Detailed explanation-1: -While visiting the Galapagos in 1835, British naturalist Charles Darwin observed local plants and animals. He became fascinated by species that seemed related to ones found on the mainland-but that also had many physical variations unique to different islands.

Detailed explanation-2: -On his visit to the Galapagos Islands, Charles Darwin also discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection. Today, there are a total of 14 of which make up the group known as Darwin’s finches.

Detailed explanation-3: -In Galapagos he found a remarkable population of plants, birds and reptiles that had developed in isolation from the mainland, but often differed on almost identical islands next door to one another and whose characteristics he could only explain by a gradual transformation of the various species.

Detailed explanation-4: -Natural selection is one of the ways to account for the millions of species that have lived on Earth. Charles Darwin (1809-1882) and Alfred Russel Wallace (1823-1913) are jointly credited with coming up with the theory of evolution by natural selection, having co-published on it in 1858.

Detailed explanation-5: -English naturalist Charles Darwin developed the idea of natural selection after a five-year voyage to study plants, animals, and fossils in South America and on islands in the Pacific. In 1859, he brought the idea of natural selection to the attention of the world in his best-selling book, On the Origin of Species.
