The theory of evolution has been studied through many scientists, who have categorized and augmented the Darwin`s theory, since its publication in 1859. On the Origins of Species influenced the social movements directly or indirectly at that time and became an important part of popular culture. Therefore, study of Darwin generated a societal transformation. The book is divided into fourteen parts: variation under domestication, variation under nature, struggle for existence, natural selection, laws of variation, difficulties on theory, instinct, hybridism, on the imperfection of the geological record, on the geological succession of organic beings, geographical distribution, geographical distribution—continued, and mutual affinities of organic beings: morphology, recapitulation, and conclusion. selection mechanisms, article by revealing also the difficulties, will leave every point or theory in a difficult situation can not explain explain weaknesses, gives place to intuition, different species can reproduce still unhealthy, albeit with one another, geology and geological evidence seized takes, continued through geological data, the geology of geography history, Geographical distribution-Continued, of organic beings: morphology, vestigial organs have been put forth one by one, and …show more content…
Hence, he focuses on some postulates of the theory of natural selection, such as some variations are passed down, more offspring are produced than can survive, and survival and reproduction are not random. Furthermore, harmony with the environment is important, so compatible one with the environment is selected and incompatible one disappears. He claims that these changes are the way of evolution which occurs slowly and in small steps from generation to generation. In this regard, Darwin shows the way of the large differences between ignorance and science. If it is said that God created the convenient environment where the creatures can live in, we forget the possibility to extinct our descendants in case the environment can change one day as a reason of a greenhouse effect. This would be a very dangerous
