Charles Darwin: The Theory of Evolution and Natural Selection

The Theory of Evolution

The theory of evolution is one of the supreme logical revolts in the history of mankind hangs dramatically our perception of the world and our place in it. Charles Darwin presented a coherent theory of evolution and has accumulated a large amount of evidence to support this theory. In Darwin, most scientists believed that the body of each adaptation of the creator. Linnaeus established the system of biological classification, which we use today, and it has done in the spirit of God's creations cataloging (Darwin, 1958).

In other words, all the similarities and differences between groups of organisms that are the result of a process of connecting the great tree of life were seen in the early 19th century, philosophers and scientists, as a consequence of the all-powerful. However, the 19th century, the number of natural historians begin to suggest the evolution of change as an explanation of the structure observed in nature. The following ideas were part of the intellectual climate of the time of Darwin.

Geologists have been to learn more about the strata or layers formed by successive deposits of sediment. This indicates a sequence of time with young people over older layers. The concept is called uniformitarianism is largely influenced by geologist Charles Lyell proceeded to decipher the history of the Earth in a working hypothesis that the current situation and processes are key to the past, investigations are continuing to monitor processes such as erosion and deposition of sediments (Futuyma 1986).

Opening of the accumulation of minerals were 18 and 19 centuries. At first I thought they were natural conclusion remains unknown, but he is still alive. According to the fossils, however, continued, it became clear that nothing of the sort of giant dinosaurs known from anywhere in the world. In addition, from 1800 Cuvier observed that the deeper layers were below the fossil species. The similarities between groups of organisms have been considered as evidence of kinship, which, in turn, suggested that the evolutionary changes. Darwin intellectual predecessors had the idea of changing relationships between organizations, but they can not provide a satisfactory explanation of how evolution occurred.

Lamarck is best known among them. In 1801, he proposed the biological evolution as an explanation of the physical similarity between groups of organisms, and the proposed mechanism of adaptive change is based on the inheritance of acquired characteristics. He wrote about the giraffe: "We know that this animal is the largest mammal living in the interior of Africa, where the soil is almost always deserted, and grass makes his views on the trees, and the constant voltage to achieve . It is a long constant is the result of all the members race, the forelegs have grown longer than the hind legs and his neck has become so tense that the giraffe, without standing on its hind legs raises his head at a height of ...
