Over the course of the last century, incidents of melanoma have steadily increased. There are various factors behind this trend, but chief among them is radical lifestyle changes adopted by people. As societies became more and more industrialized, activities involving sun-exposure had correspondingly declined. No more do a majority of people spend hours in the farm or participate in communal outdoor activities. With our bodies and skin thus conditioned to minimal sunlight, sudden bursts of exposure could prove dangerous. With tanning of skin becoming an obsession among fair-skinned women, young white women are particularly at high risk for developing melanoma. There is also an environmental dimension to the steady rise of skin cancer cases across the world. This has to do with the depletion of the earth’s ozone layer. This allows an excessive amount of Ultra Violet radiation to filter through the atmosphere. Although application of sunscreen and protective clothing somewhat . . . Read More
- What is the thesis (the central idea or main point)?
Richard Dawkins’ main argument is that the forces of evolution give an illusion of deliberate design, whereas in truth, they were shaped by gradual and random mutations sifted by the filters of natural selection.
- What are the main arguments made in supporting the thesis?
Drawing on the analogy of the watchmaker by William Paley, Dawkins produces his polemic by systematically dismantling the theory by design as applicable to life forms on earth. Dawkins shows that random mutations at the level of the DNA, when filtered and selected under the process of natural selection, gives rise to sophisticated and specialized species. His main argument is that there is no need whatsoever for invoking divine intervention in explaining variety and magnificence of life on earth.

The debate surrounding abortion has been a part of public policy discourse for more than half a century now. Despite widespread exposure to the issue and passionate presentation of views there is no generally accepted consensus. Apart from universally recognized pros and cons for legally permitting abortion, there are also localized cultural sensibilities to contend with. For example, regions of the country with a large religious demographic tend to oppose abortion even when it is practically unreasonable. On the other extreme, in the more liberal states region, there is the danger of abuse of the right to abortion by reckless, indulgent teenagers. This essay will argue that abortion must be exercised only under exceptional circumstances. Four key readings related to the topic are perused for constructing arguments.
Dan Marquis’ essay “Why Abortion is Immoral” clearly suggests that the author looks cannot see any genuine moral grounds for permitting . . . Read More
The human sensory faculties, in addition to the processing power of the brain, play a vital and definitive role in how knowledge is acquired. The five major sensory faculties are sight, smell, hearing, taste and touch. Cognition is the higher faculty that integrates and interprets inputs from these five senses. But what is also interesting is that the brain, rather than being a passive recipient of inputs also directs and conditions the other sense organs. This makes the brain the most powerful sense organ, for it can potentially control the flow and the meaning of information that is gathered through the five basis sensory inputs.
There are several factors that determine the accuracy of sensory information. The quality of the information source is one and the health of the receiving sensory organ is another. The conduciveness of the medium of transmission is also a key factor. The way these three factors interact and compound is best illustrated through the . . . Read More
The advent of molecular genetic diagnostics has opened up new opportunities in the field of preventative and restorative healthcare. The newly available genetic diagnostic technologies have given rise to legal and moral conundrums that have not been sufficiently resolved. Just as the debate on the broader implications of genetic technology continues, the number of patients willing to avail of the technology is also on the rise. Such trends are witnessed here in the United Kingdom, as elsewhere in the industrialized world. This essay will discuss the molecular genetic diagnostic techniques . . . Read More
In the last decade or so, the applications of forensic science in criminal investigation have increased. For all sorts of criminal allegations, including rape and murder, the services of forensic scientists are being employed. The infiltration of forensic science into the field of criminal justice is so deep that courses in police academies have included it in their syllabus. While the academia is catching up with advancements in technology, the media on the other hand plays a role in popularizing forensic science for the general public. Television soap-operas such as E.R., NYPD, CSI, CSI Miami, Forensic Files, etc. and science based re-enactment shows such as Medical Detectives which reach a wide TV audience have brought forensic science into the mainstream cultural discourse.
While the application of scientific methods to criminal investigations have a long-standing historical association, recent developments in Genealogy and DNA mapping have had a profound . . . Read More
