"Evolution: Three products of evolution"

Download file to see previous pages Fleagle (2001, pp.17) indicates that, the misconceptions on evolution will remain persistent among various analysts and researchers. Though some of the misconceptions may be regarded as misunderstandings, Lloyd (2001, pp.33) advocates for a comprehensive survey on the topic prior to making any decisions regarding the theme. This essay shall aims at highlighting three products of evolution- adaptations, by-products noise- and the debates that have surrounded these themes. Changes that have taken place after the origin of life will also be discussed in the essay, in an endeavor to explain the evolutionary changes. Regardless of the debates on the origin and changes of life, the processes need to be carefully evaluated in order to have an understanding on the occurrence of these evolution processes. 1.1. Adaptations Adaptations, as a product of evolution, works on the basis that, inborn characteristics that are acquired through inheritance tend to develop through a process of natural selection. Buss (2004, pp.44) argues that, as these processes develop, they are able to solve certain problems that the concerned individuals may have undergone. These problems are related to survival issues as well as, reproductive ones. Williams (2003, pp.11) indicates that adaptation is an inherited attribute that emanates from inheritance and greatly relies on natural selection. Over the years, inherited characteristics have been credited with their abilities to tackle issues that may come up as a result of reproductive. One of the most cited examples of adaptations is the umbilical cord that is useful for survival of the baby during growth whilst in its mother’s womb. For the baby to survive, it has to feed. Feeding can only take place, in this context, through the mother. In this context, therefore, the umbilical cord can be regarded as an adaptation that suits the baby, in terms of feeding and acquiring the necessary nutrients sufficient for growth. The heart can also be cited as another example of adaptations by human kind. It is through the heart that oxygen flows through the body. The heart connects to survival, a reproductive aspect that all individuals undergo at certain stages of their lives. Through staying alive, the cycle of reproduction continues. In relation to adaptations, natural selection is the root of inventing the forms of adaptations that humans need to encompass in order, to continue to exist. Essentially it is justified to pose the claim that, natural selection is the root of all adaptations that human beings undergo. Adaptations are known for their ability to specialize on specific roles in the body; they also reappear amongst age bands, develop with time as well as portray attributes of design among generations; thus affecting reproductive in an indirect manner. Adaptations generally are all those aspects that are likely to affect reproduction, like the process of giving birth, looking for food among others (Oftedal et al, 2009, pp.49) 1.2. By-products By products, according to Robins, Pervin and John (2008 pp.34) have been described as the characteristics that are linked with adaptations so as to allow individuals survive in their environments. By products are not known for their abilities to solve adaptation problems, but simply provide assistance to the adaptive. Pollard (2000, ...Download file to see next pagesRead More

...?Evolution Evolution can be defined as the modification of living organisms through time as they descend from their ancestors, generation after generation. The ancestors of various species look different in their structure, behavior and physiology back in time. Prior to Darwin, though some naturalists had speculated about modification of species, they failed to explain why and how species change. They also believed that evolution began with special creation of only a fixed number of species. Partially influenced by Thomas Malthus' essay on the Principle of Population and stimulated by a letter from Alfred Russell Wallace, Charles Darwin in 1859 discussed the evolution of species through natural selection in his famous work titled... one of...

...?EVOLUTION Even in this period of great technological advancements and overwhelming scientific discoveries, there is still an ongoing debate of how we, as human beings, came about the way we are now. There are numerous theories on the issue and at the forefront is the theory of Evolution. It is this paper’s position that the human race came about as they are now through the process of evolution. The author believes that living organisms today evolved through the process of natural selection and this has been the key to the survival of living things on earth. There is an overwhelming body of evidence which supports the theory that life on this planet started from a single living...

Biological science also undergone tremendous growth in the past and now the theories of evolution became more and more understandable to the ordinary people. Advances in genetics helped the biologists a lot in explaining the basis of variation and inheritance. Theory of evolution or the theory of natural selection influences all the aspects of modern biology. This paper briefly analyses the principles of evolution with the help of some specific traits among living things. The...

...Evolution British novelist Arthur Koestler once quipped that the human brain is, " the only example of evolution providing a species with an organ which it does not know how to use". Indeed, the human brain, and its capacity for imagination and abstract thought, has made the topic of evolution one of the most debated and controversial issues of our time. Lines are often drawn along religious beliefs that reject the theory of evolution, while other camps argue that the theory is fact. Evolution is often misunderstood and has challenged scientists to provide proof for the belief that all life transforms, progresses, and adapts to its environment. The...

Evolution debate, more commonly known as the creationism v. evolution debate as opposed to what most people believe has been in existence even before the theory of evolution and Charles Darwin, but unlike prior centuries wherein people used to fight over who did it, after Darwin it’s about ‘What happened?’. Evolution has been criticized since the magnitude of anti-evolution moments of the 19th century by Christians and many other religious entities alike. This essay sheds light on ‘how does...

...the primates to change their habitat from tree to the land that brought together the most atrocious forces of marauders on the land area of the globe. Such stories then connect the different varieties of wild animals found in African forests these days. In addition, such transformation from tree dwelling to ground-inhabitants provided the opportunity of humans to evolve into civilized ones by benefiting from these predators roughly five million years ago. From these three theories (Bowler, 2004) discussed in brief, the theory of evolution of Darwin stands distinctively as the most popular, influential, and factual theories related to evolution. In the beginning, ‘descent with...

...Evolution Evolution Charles Darwin who believed that species undergo changes from generation to the next pioneered the theory of evolution. He called these minima changes microevolution and argued that the small changes accumulated over a long period resulting in macroevolution. Macro evolution is the term used to refer to the process where inherited traits in a species change from generation to generation resulting in variations, which accumulate over a long period of time causing new species to emerge. According to scientists, macroevolution entails variation, reproduction, and selection processes, which act together to cause the changes in traits. Although Scientists...

...Evolution The past and contemporary paradigms of biology are uniquely held by the theory of evolution. Evidently, the evolution is credited with uniting biological fields such as paleontology, genetics and microbiology. Moreover, evolution offers an elaborate explanation on the existence of the Earth’s ubiquitous diversity and the origins of the over five million species of plant and animal life. To this end, evolution is distinctively explained by several theories. Evidently, the pre Darwinian theorists such as James Usher advanced the creationism version of evolution (Ruse & Travis, 2009). The creation theory of evolution theorized that the infinite life forms in the Earth were created by God. Moreover, the creation theory... evolutionist...

Blowback, the definition of evolution and deep time are the three underlying concepts that must be understood. Evolution had its much needed deep time. However, it will require a very long time to construct many wonders of biology as evolution is based on random change. The story changed a century later. According to science, as populations respond to environmental challenges and shifts, the remarkable changes come about...

.... There are three main evolutionary transition trends specified by the fossil record i.e. fish to amphibians evolution, reptiles to birds and whales to terrestrial mammals evolution (Coyne, 2009). Accordingly, there are three important insights that emerge from the fossil record. Firstly is that the fossil spells out the evolution process (Coyne, 2009). The records within rocks provide a great deal of confirmation on the part of evolution theory. The other lesson is that transitional forms often occur in the fossil record in the exact manner that they should. For instance, after the dinosaurs, the earliest birds occurred, and the modern...
