Similarly the birds who had beak shaped beaks conjured up the resources from the environment like nectar from flowers etc and they were also in a very good position. Natural selection refers to being in a very good position and being able to reproduce. This whole process is referred to as Natural selection." (Darwin and Natural Selection, 17 April 2009).
"Charles Darwin is believed to be the founder of this theory and he conducted a research in the 19th century on an island where he found that organisms that suit better to the environment are more likely to survive than the organisms that don't suit the environment." (Theory of Natural Selection, 17 April 2009).
The above diagram shows the evolution of beaks of these birds; their beaks are instrumental in determining how much food they get. Their beaks enable them to survive in different ecological conditions, the birds that eat grubs have a thin and an extended beak and the same enables them to poke into various holes and get the grubs. Finches that eat fruits and similar items would be less successful in doing so because their beaks don't allow them to do so. Peppered Moth is a classic example of Natural selection; Industrial melanism is a process that occurs in these species. This process has become very common since the beginning of the industrial age. The pollution let out by industries and vehicles would collect on the sides of several buildings and the same changes the color of the buildings making the buildings darker. The Peppered Moth is usually light in color and the predators that eat Peppered Moth can easily catch and feed upon the moth because of its evident visibility against the dark background caused by pollution. After a point in time the process of mutation took place in these species of Peppered Moths and these days, they have become darker in color when compared to the white Peppered Moths, this means they have again become very difficult to trace and hunt for predators that feed upon them. In this particular case, the process of Natural Selection ...Download file to see next pagesRead More

... and results of application of pesticides. Interaction between adaptation and chance are the conflicting agents in the process of natural selection. When we say variation is the key concept, the role of lineages that are engaged in competition goes to prove the importance of natural selection. Biological species are not unchangeable entities and they are ever on the flux. Regina Bailey further states, “Natural selection is the process by which biological evolutionary changes take place. Natural selection acts on populations and not individuals….. Evolution suggests that all life is connected and can be traced back to one common ancestor. A literal interpretation of biblical creation suggests that life was created by an all-powerful...

...s generation for habitat 1. In this habitat, all the preys increases from generation 1 to generation 2. Also, the trend is the same in generation 2 to generation 3 save White only. Conclusions As the Number of predators increases, the number of preys decreases. This is due to the fact that an increase in the number of predators results into more preys being eaten and as a result, their (prey) number decreases. Also, as the number of predators decreases, the number of preys increases. This is attributed to the fact that the decrease in the number of predators’ results into less preys being killed thus their increase in number. References Williams, George.

... of design in nature. This relates to the patterns as discussed by Eldredge in the sense that when a certain species is bred with another one from different part of the world, it leads to creation of new patterns of species that are well adapted to the environment. 3. Why might the idea of natural selection be considered a dangerous idea? It is a dangerous idea since it bases its argument on the ground that species once developed or created can never transform which is not correct. For instance, gene duplication is able to form different species resulting from the same parental organism mainly because of polyploidization. 4. Find one example to illustrate how the concept has been misused For instance, a common rhea that Darwin located...

Level of threats Notably, the spill of oil in the Mexican sea poses immense level of threat to the plants and animals that cohabits within the marine wetland and other ecosystems. The level of threat is evident since the oil has been affecting the growth of natural resources such as tress, grass and others that acts as homes to certain animals, death of the plants, and contamination of the environment (Pallardy, 2014). The oil has been contaminating water that provides primary productivity incentives relied upon by the many species along the water...

...heterozygotes. To this end, it has been ascertained that carriers for different chromosomal variations occur at different frequencies at different seasons. Such genetic constitutions can be passed on to offsprings. This leads to some offsprings that are better suited to environmental disparities, while others are least suited to prevailing environmental conditions. In this article, the variations in seasonal adaptability among natural populations of Drosophila pseudoobscura are analyzed. Basically, the article unveils a study targeted towards determination of the impact of the gene combinations on the third chromosome of Drosophila pseudoobscura in their adaptation to varied environmental setup. It aims to show that natural selection...

Commonsense Reasoning in and over Natural Language

The theories and theorems that are involved in quantifying language fail to provide us a limitless and potentially useable formula for quantification regardless of their complexity and their rationale supporting it.

Jon Barwise and John Etchemendy in Language Proof and Logic give a very understandable argument as to the reasons for quantifiers and the reasons they are not always accurate in their use. A very pertinent consideration for their argument starts out their ninth chapter in Language Proof and Logic by saying, “In English and other natural languages, basic sentences are made by combining noun phrases and verb phrases.” (1. Chapter 9 page 227, Language Proof and Logic.) The consideration continues fu...

Factors Affecting Fast Food Restaurant Selection in Britain

Over the years, fast food has become the most preferred food for consumption because of its availability, affordability, and easy way of making them despite the health consequences associated with it. As much as fast food joints are available in almost any location in Britain, consumers tend to apply several factors before selecting a fast food that they can eat from depending on their preference and the affordability of the food sold in these establishments. According to Thomson (1994), most of these establishments tend to be on strategic places such as in the motor service station, high streets and shopping centers that become tempting for consumers and influence their selection.  Essentially, customers seek to acquire a ce...
