Summary Theory of Evolution by Natural Selection. According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title On the Origin of Species 1859†. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmental factors is due to the ancestral trait. The evolutional theory was supported by great body of evidence from various scientific disciplines. Natural selection is the main fundamental tool used in the theory of evolutional change. Natural selection in evolutional theory is the process responsible for the evolution of adaptive behaviors. Without the knowledge of natural selection in evolution, it will be very difficult to understand how organism display their diversity and their tough behavior to adapt and survive in an environment. The theory of evolution by natural selection has two main points: ïÆ'Ëœ All life on Earth are connected and are related to each other, and this variety of life is said to be a product of changes of species by natural selection in which some traits are favored by environment factors over other species. ïÆ'Ëœ Natural selection depends on the ability of an organism to attract a mate. An example of this process is the peacock’s colorful fluff and a male deerShow MoreRelatedThe Theory Of Evolution By Natural Selection1329 Words   |  6 PagesThe theory of evolution by natural selection proposes that all species are related (Eade, S. and profile, V. 2014). There is estimated to be between 6 million and 100 million different species in the world, with more species undiscovered than those discovered; this is all owing to the concept of evolution (Borenstein, S. 2014). Evolution is defined as the â€Å"change in the characteristics of a species over many generations (Linstead, 2012).† The most widely accepted theory of evolution is natural selectionRead MoreNatural Selection And The Theory Of Evolution1536 Words   |  7 PagesNatural selection and The Theory of Evolution were just two of the things that Charles Darwin conquered through the exploration of The Galapagos I sland. Darwin was born on February 12, 1809, in Shrewsbury, England. While Darwin was still in high school, his main interest was nature, he was especially interested in beetles. Darwin’s father, Robert Darwin, who was best known as the father of the naturalist Charles Darwin, wanted Charles to become a doctor.

In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change through individuals.

He believed that species differ over time and space.
