Research Paper Example Moreover, the article elaborates on the several facets of evolution. This includes the notion that all living species share a common ancestry. Consequently, the theory states that there exists a relation among the entire world’s species. The second facet pertains to the process of natural selection that drives evolution. Evidently, the natural selection process is also known as the survival of the fittest. Thus, the author offers an explanation of survival of the fittest theory or the natural selection process. Evidently, the theory was formulated by Darwin who believed that all species struggled to fight for limited resources. However, Darwin theorized that each individual species possessed a difference in gene superiority that exhibited greater survival chances. "What is Evolution?"Â  Science – AllAboutScience.org. allaboutscience.org, n.d. Web. 27 Nov. 2012. . The article begins by delving into the definition of evolution. To this end, it defines evolution as a syst ematic process whereby an organism undergoes change into a more complex and enhanced form. Moreover, the article acknowledges that the evolution theory has been used to explain life on earth. In addition, the article elaborates on the various components of evolution. ... In reference to micro evolution, the article stipulates that there are variations that occur within a species. For example, micro evolution is used to explain how wolves, foxes, dogs, coyotes, jackals and dingoes evolved from a parent pair of dogs. Incidentally, the variations occur in a downward manner and are limited by genetic codes. This means that species such as dogs do not develop new limbs such as wings and change to flying. To this end, there is neither loss in genetic information nor any further addition. On the other hand, macro evolution relates to the important or greater changes in the primary functions by organisms. Moreover, macro evolution involves change from a particular kind of animal or plant into another. In addition, it occurs after several genetic mutations as opposed to during the life of a single organism. Thus, macro evolution attempts to offer an explanation of how the millions of different species came into existence. Kim, Seongcheol, Pudur Jagadeeswaran, Vrinda Kulkarni, and Maira Carrillo. "PLOS ONE: Evolution of Primary Hemostasis in Early Vertebrates."Â  PLOS ONE: Accelerating the Publication of Peer-Reviewed Science. PLoS ONE, 1 Jan. 2009. Web. 27 Nov. 2012. http://www.plosone.org/article/info%3Adoi%2F10.1371%2Fjournal.pone.0008403. The primary research article delves into the evolution of primary hemostasis in early vertebrates. To this end, the authors define hemostasis as a defensive system that protects an organism by stopping bleeding when an injury occurs. Evidently, the researchers discovered that the main hemostatic factors in mammals were present in the early vertebrates. Moreover, they acknowledged that the exposure of the vascularised
