British naturalist Charles Darwin may be the most influential scientist to have visited the Galpagos Islands. This makes for a strange mix of tropical and temperate climates. On 15 September 1835, a young geologist and amateur naturalist named Charles Darwin first arrived in the Galpagos Islands. Each major island, with the exception of the largest island, Isabela, consists of a single large volcano. They used the salt to cure fish and to fill the infrequent demand produced by heavy rains flooding the coastal Salinas saltpans on the mainland. The researchers suggested that the relatively common lichen orchil, or Dyers Moss, Rocella gracilis, which produces a mauve dye, had economic potential. Since their discovery, our decisions about what to do with these islands have had huge consequences. At the turn of the century, scientists had already noted the consequences of whalers, tortoise oil hunters, and invasive species. Darwin, evolution, & natural selection (article) | Khan Academy Most of the islands have a distinctive conical shape that is often associated with volcanic action. In 1944, the Ecuadorian government established a third colony on Isabela, with 94 criminals arriving in 1946. They lie around 605 miles off Ecuadors coast and you can easily access them by flying from Guayaquil or Quito on the mainland. Darwin was responsible for surveying rocks and volcanoes, but he also noticed, curiously, many of the mockingbirds, finches and tortoises were different from one island to the next. Until 1996, over 30% of the Japanese catch came from Galapagos and about 30% of this, by weight, was Blue and Thresher Sharks. Jackson.). The world first heard about Galapagos more than 470 years ago. Charles Darwin set sail on the ship HMS Beagle on December 27, 1831, from Plymouth, England. His experiences and observations helped him develop the theory of evolution through natural selection. In 1831, the young man started his 5-year expedition aboard the HMSBeagleafter persuading the Captain, Robert FitzRoy, to let him tag along as the ships naturalist. They are part of the country of Ecuador, in South America. At Floreana, Darwin had the opportunity to gather species and collect the second bird that would lead to his important conclusions later on. While the crew of the HMS Beagle mapped the coastline of South America, they traveled to a group of islands called the Galpagos. The Galpagos Islands were the source of Darwin's theory of evolution and remain a priceless living laboratory for scientists today.
