The Proces of Evolution - 653 Words

Without evolution, and the constant ever changing environment, the complexity of living organisms would not be as it is. Evolution is defined as a process that results in heritable changes in a population spread over many generations (8).Scientists believe in the theory of evolution. This belief is based on scientific evidence that corroborates the theory of evolution. In Figure 1 the pictures of the skulls depict the sequence of the evolution of Homo-sapiens. As the figure shows, man has evolved from our common ancestor that is shared by homo-sapiens. The change of diet of homo-sapiens over time has thought to contribute to the change in jaw structure and overall skull shape. The process of evolution comprises of many complex of mechanisms. These mechanisms fundamentally allow the progression of speciation and adaptation to occur. There are 4 common kinds of evolutionary mechanism of change: Natural Selection, Genetic Drift, Mutation and Migration. Natural selection is based on the concept â€Å"survival of the fittest† where the most favourable individual best suited in the environment survive and pass on their genes for the next generation. Those individual who are less suited to the environment will die. Another mechanism is a hereditable type of evolution is mutations. Mutations are alterations to a gene. Mutation can be harmful, beneficial or neutral. Mutations are the origin of the source of genetic diversity (9).Mutation that are harmful, hinders the chances of theShow MoreRelatedRealism and Film Form1980 Words   |  8 Pagesworks with, but colors and lines, while reality is at the base of cinema, which originally, before being an art, was a mechanical proces designed to record the world.
