Detailed explanation-1: -San Cristobal Island was the first island Charles Darwin visited arriving to the Galapagos on September 16th, 1835. The Beagle anchored in a calm bay on the south of the island, near the actual capital of the Galapagos. The Beagle spent eight days surveying the coast.

Detailed explanation-2: -Charles Darwin in the Galapagos. Perhaps our first association with the word “Galapagos” is the name “Darwin.” Darwin’s visit to the Galapagos Islands had a resounding impact on the formation of his Theory of Natural Selection.

Detailed explanation-3: -On the Galápagos, Darwin found plants that were related to daisies and sunflowers–but grew to the size of trees. Like the marine iguanas, these island residents seemed to have adapted to their environment: with plenty of sun and little competition, daisies and cactuses could grow to the size of trees.

Detailed explanation-4: -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-5: -Most of this data came from his long voyage on the HMS Beagle to South America. Particularly, their stop at the Galapagos Islands proved to be a gold mine of information for Darwin in his collection of data on evolution.
