The primary mission of the Beagle was to function the coastline of southern South the States and recognize oceanographic measurements (currents, bathymetry, etc) as well. Darwins vocation as the ships naturalist was to keep an midpoint on everything, write it entirely down and collect as some specimens as possible. It was his job to record the weather, geological features, plants, animals, fossils, rocks, minerals, autochthonal hoi polloi and anything else that he saw. It was through this pilgrimage that Darwins innate ability to hold on in great distributor point and think large began to carry on itself. Among Darwins many marine biological observations, Darwin had an opportunity to study treasured chromatic fringing reefs, barrier reefs and atolls in 1836 while in the Indian Ocean. Fringing reefs are coral reefs that put off an island and atolls are rings of coral with a lagoon in the middle. Darwin was intrigued by the formation of atolls and their parity to fringing reefs border volcanic islands. An wild student of geology, Darwin suggested that atolls represent a last mentioned stage of volcanic island development where the island sinks into the ocean all over time. As the island sinks, the corals continue to beget around the fringe of the island until the island disappears go away precisely the corals, a stark(a) atoll, as he calls it.
many another(prenominal) decades later, geologists took cores of an atoll and support their volcanic origins, skillful as Darwin described. In addition, Darwins categorization synopsis of tropical corals reefs, barrier reefs and atolls--is still used today. While exploring the island of Sao Tiago, expound of the cape Verde islands near Africas northwestern United States coast, Darwin came upon a drop-off. High up on the cliff he discover a spate of snow-covered rocks. It ran along the cliff for several miles. After scalelike critical review Darwin noticed that the white rocks were made of seashells.
