    Organisms acquire certain traits through various means which have been formulated in several theories. Traits of organism can be traced through successive generations. This change in traits through successive generation is referred to as evolution. The trait acquired may seem to be small but the accumulation through various generations creates a significant change in population. New species arise due to the traits acquired. This is an indication that all species share the same ancestor. Evolution involves transfer of genes from a generation to another. The inherited traits are produced by the genes passed over. It is not all the population that shows the same traits as a result of gene transfer (Haught, 19). Variations occur depending on the population involved. There are various forces which are responsible for evolution. There are forces behind variation while others affect the variants. Gene mutation is one of the processes which bring about variation. Gene transfer may either occur in populations or species. Variation occurring in organism may be contributed by genetic recombination. There are distinct processes that make variants to be pronounced in population. Natural selection is one of the processes that contribute to certain traits in populations.

    Darwinian evolution is a theory that explains the origin. This theory considers all life to be related in a way. Life is perceived to originate from a common ancestor according to this theory. This theory assumes that all organisms are related. This includes plants to animal species. Life is perceived to have developed from non life. Some of the complex creatures are believed to have descended from simple ancestors. This takes a couple of years. Gene mutation brings changes in the orientation of genes. There are some mutations which are beneficial for continuation of life (Ruse, 52). These mutations are preserved since they are beneficial. This involves natural selection. Natural selection involves the transfer of beneficial mutation from a generation to another. The accumulation of the beneficial mutations brings about a new species. It may happen that the organism formed may be totally different from the original organism. In essence a different creature occurs in natural selection.

    It is through natural selection that small genetic mutations are accumulated to which about a new creature. An organism may acquire a functional advantage which is transferred to other generations. The offspring of the organism inherit the advantage. All the other members who are inferior do not survive. In this case, the members who are superior in a certain species survive. The functional advantage is preserved through natural selection. It enables fair competition. It is clear that only those species which are superior are allowed to survive. The equivalence of the process is the domestic breeding of species. It is been the trend to breed species at home (Alland, 29). This has been possible by eliminating the undesirable traits. Undesirable traits are traits which may not compete well with other organisms. The functional advantage is achieved by eliminated these traits which are not competitive enough. The same way breeders eliminate undesirable traits within a certain time, it is also the same for natural selection.

    There are several strengths of this research. Darwinian evolution is considered to be a slow process. The process of evolution is believed to go through successive steps which lead to accumulation of beneficial traits. The transfer of genes from one generation to another leads to preservation of desirable traits. This research is applicable since it highlights on how breeders use the method of natural selection in domestic breeding. The functional advantage leads to creation of a new creature with superior traits (Low, 97). Those with minor traits are eliminated.

    Darwinian Theory explains on the concept of life. It is my opinion that, the research carried out on natural selection is a strong theory. It is through natural selection that genetic mutations are maintained in successive generations. This process is based on certain facts there is the fact that the number of offspring is more. It is in populations that variation exists. The ability of reproduction and survival vary in offspring. Competition of organism is possible due to these simple facts. They provide a good ground for reproduction and survival. The organisms carrying traits which are beneficial compared to their competitors pass these traits to next generation. The traits which are not beneficial are not passed to the next generation. In my opinion, this research is essential since it provides tricks of survival (Gertrude, 33). It is survival for the fittest. The ability of an organism to survive and reproduce defines the fitness of the organism. The fitness of an organism is determined by the genes transferred.

    In conclusion, Darwinian Theory of evolution elaborates on the origin of life.  It considers life to have descended from the same ancestor. All forms of life, plants to animal species adopt certain traits. Genetic mutation leads to creation of genes which confer genes which contribute to beneficial traits. These genes have functional advantage. Organisms with this functional advantage are allowed to survive while those with minor traits are eliminated. This elimination enables a competitive ground for the organisms spared.
