Presentation Charles Darwin Biography

In the year, 22 years Darwin, as a naturalist, went on a round -the -world trip on the expedition ship of the Royal Fleet "Bigl", from where he returned to England only on October 2.

Darwin spends most of the time on the shore, studying geology and collecting collections on natural history, and Bigl carried out cartographic filming of the coast. During the trip, he carefully records his observations and theoretical calculations. During the trip, he made a number of descriptions of the geology of various regions, collected a collection of animals, and also made a brief description of the external structure and anatomy of many marine invertebrates.

During the first stop off the coast of Santiaag, Darwin discovers an interesting phenomenon - volcanic cliffs with shells and corals, sang under a high lava temperature in a solid white rock. Darwin’s research on Santiaga on the islands of the Green Cape showed the superiority of the method applied by Layelle geological changes for a long period 2. At the Punta Patagonia place, he makes an important discovery.

Darwin discovers a petrified giant disappeared mammal. The remains of this animal were in rocks next to the sinks of modern types of mollusks, which indirectly indicates a recent disappearance. It defines the find as a little -known megaterial, with a bone shell, which was like a giant version of the local battleship. The emergence of new species is subject to a certain pattern.

In Chile, Darwin became a witness to a strong earthquake - the earth has just risen. This rising layer turned on the shells of double mollusks, which turned out to be higher than the level of high tide. High in the Andes, he also found shells. Just as when raising sushi, the shells are high in the mountains, when lowering seabers, the oceanic islands go under water, and at the islands from coastal coral reefs, barrier reefs are formed, and then the atolls of the study of coconuts.

In the Galapagos Islands, Darwin noted that some representatives from the Mockingbird family differ from those in Chile and each other in different islands, indicating the ways of changing living forms depending on the state of the environment. During the trip, Darwin crossed the three oceans, visited the island of Tenerife, the islands of the green cape, the coast of Brazil, in Argentina, Uruguay, on fiery land, in Tasmania, on coconuts, in Patagonia, Chile, Galapagos, from where a large number of observations brought, collecting collections Colonies in South America.

Interesting natural phenomena are ice crystals of a special form of penitentesses formed on the surface of glaciers in the Andes.
