Natural selection is an important part of evolution. Natural selection occurs when members of some groups are better suited for survival and breeding than other groups in that group (Phelan 284-85, 2011). The environment where living beings are also part of natural selection. Depending on environmental conditions, organisms can pass selected traits to their descendants. These selected functions will allow the next generation to better adapt and survive longer.
During the past several decades, the evolution of the interpretation by the natural selection of Charles Darwin, it has been challenged to another theory called intelligent design. Science teachers and the Board of Education work hard to introduce facts to the students. Despite discussions there is controversy. How should students learn about the life history of this planet? Is Christianity and other major religions incompatible with Darwin's theory of evolution? Is there evidence to support the new theory of intelligent design? Can ID and Darwin find out in common?
Jonathan Wells has proposed an intelligent design but, in fact, Darwin's theory is hard to believe that some of the characteristics of an organism appears to have been designed. Natural selection and random variation do not explain Darwin's theory of evolution. Wells supported his remarks using two examples of Darwin himself, finch and four flying fruit flies. Darwin's finches and four birds of fruit flies proved his theory of evolution, but Wells has revealed that it is possible that the theory of Darwin to explain certain features, rather than all of the features of the organism. In general, the shape of a cockroach depends on the bird, and Darwin concludes that have the form of cockroaches is different because of the diversity of food eaten by birds. In other words, Finch adapts to various foods, but evolves from a common ancestor and undirected process, natural selection is the reason for this diverse collection of finches.
To some extent, the term "survival of fittest" first proposed in Darwin's natural selection theory is a brief description of eugenics. Darwin and Alfred Wallace submitted a paper on the concept of natural selection in 1858. This concept has become the backbone of modern biology. Later Darwin published an influential book in 1859. "Origin of species by natural selection, or protection of dominant race in life struggle". Eugenics (/ juːdʒɛnɪks /; derived from Greek), "Born from Europe", "Good, Good", "Ethnicity, Stocks, Relatives" is a series of beliefs aimed at improving the genetic quality of the population and It is a custom. Broadly speaking, there are two types of eugenics: positive (encouraging breeding) and negative (encouraging discussion). It is not suitable for breeding)
