A Brief Explanation of Evolution

The theory of evolution is a scientific theory that essentially states that species change over time. There are many different ways species change, but most of them can be described by the idea of natural selection. The theory of evolution through natural selection was the first scientific theory that put together evidence of change through time as well as a mechanism for how it happens. History of the Theory of Evolution The idea that traits are passed down from parents to offspring has been around since the ancient Greek philosophers time. In the middle 1700s, Carolus Linnaeus came up with his taxonomic naming system, which grouped like species together and implied there was an evolutionary connection between species within the same group. The late 1700s saw the first theories that species changed over time. Scientists like the Comte de Buffon and Charles Darwins grandfather, Erasmus Darwin, both proposed that species changed over time, but neither man could explain how or why they changed. They also kept their ideas under wraps due to how controversial the thoughts were compared to accepted religious views at the time. John Baptiste Lamarck, a student of the Comte de Buffon, was the first to publicly state species changed over time. However, part of his theory was incorrect. Lamarck proposed that acquired traits were passed down to offspring. Georges Cuvier was able to prove that part of the theory incorrect, but he also had evidence that there were once living species that had evolved and gone extinct. Cuvier believed in catastrophism, meaning these changes and extinctions in nature happened suddenly and violently. James Hutton and Charles Lyell countered Cuviers argument with the idea of uniformitarianism. This theory said changes happen slowly and accumulate over time. Darwin and Natural Selection Sometimes called survival of the fittest, natural selection was most famously explained by Charles Darwin in his book On the Origin of Species. In the book, Darwin proposed that individuals with traits most suitable to their environments lived long enough to reproduce and passed down those desirable traits to their offspring. If an individual had less than favorable traits, they would die and not pass on those traits. Over time, only the fittest traits of the species survived. Eventually, after enough time passed, these small adaptations would add up to create new species. These changes are precisely what makes us human.   Darwin was not the only person to come up with this idea at that time. Alfred Russel Wallace also had evidence and came to the same conclusions as Darwin around the same time. They collaborated for a short time and jointly presented their findings. Armed with evidence from all over the world due to their various travels, Darwin and Wallace received favorable responses in the scientific community about their ideas. The partnership ended when Darwin published his book. One very important part of the theory of evolution through natural selection is the understanding that individuals cannot evolve; they can only adapt to their environments. Those adaptations add up over time and, eventually, the entire species has evolved from what it was like earlier. This can lead to new species forming and sometimes extinction of older species. Evidence for Evolution There are many pieces of evidence that support the theory of evolution. Darwin relied on the similar anatomies of species to link them. He also had some fossil evidence that showed slight changes in the body structure of the species over time, often leading to vestigial structures. Of course, the fossil record is incomplete and has missing links. With todays technology, there are many other types of evidence for evolution. This includes similarities in the embryos of different species, the same DNA sequences found across all species, and an understanding of how DNA mutations  work in microevolution. More fossil evidence has also been found since Darwins time, although there are still many gaps in the fossil record. The Theory of Evolution Controversy Today, the theory of evolution is often portrayed in the media as a controversial subject. Primate evolution and the idea that humans evolved from monkeys has been a major point of friction between scientific and religious communities. Politicians and court decisions have debated whether or not schools should teach evolution or if they should also teach alternate points of view like intelligent design or creationism. The State of Tennessee v. Scopes, or the Scopes Monkey Trial, was a famous court battle over teaching evolution in the classroom. In 1925, a substitute teacher named John Scopes was arrested for illegally teaching evolution in a Tennessee science class. This was the first major court battle over evolution, and it brought attention to a formerly taboo subject. The Theory of Evolution in Biology The theory of evolution is often seen as the main overarching theme that ties all topics of biology together. It includes genetics, population biology, anatomy and physiology, and embryology, among others. While the theory has itself evolved and expanded over time, the principles laid out by Darwin in the 1800s still hold true today.

Juvenile Diabetes A Disease That More And More Children...

Juvenile Diabetes is a disease that more and more children are getting each day and it affect about 0.1 percent of children that are school age. There are two types of diabetes that are common in children. The first one is type one diabetes and the second one is type two diabetes. There are major health problems associated with type one including troubles physically, a multidisciplinary approach by physician, nurse and dietitian is needed to treat juvenile diabetes. In patients with new onset type 1 diabetes, lifelong insulin therapy must be started. As a chronic disease diabetes mellitus requires long term medical attention both to limit the development of its devastating physical and psychological complications and to manage them when they do occur. As for the ADA (American Diabetes Association) Diabetes Mellitus is a disproportionately expensive disease; I read that in 2002, the per capita cost of health care was $13,243 for people with diabetes, while it was $2,560 for those with out diabetes. As of now there is no cure for Juvenile Diabetes but there is ongoing research to test medications and new products to find a cure for Juvenile Diabetes. There are however many coping methods, support groups, counseling, insulin injections and pumps that children with juvenile diabetes make a part of their everyday lives.

Abolition of the Transatlantic Slave Trade free essay sample

The struggle to end the transatlantic slave trade and slavery was achieved by African resistance and economic factors as well as through humanitarian campaigns. The most prominent abolitionists, notably Thomas Clarion and William Wildflower, were great publicists. Wildflower (1759-1833) led the British parliamentary campaign to abolish the slave trade and slavery. Opinion in Europe was also changing. Moral, religious and humanitarian arguments found more and more support. A vigorous campaign to achieve abolition began in Britain in 1 783 and also developed in North America and the Caribbean, often led by the Black churches.In Britain, Thomas Clarion (1760-1846) was another prominent campaigner who was principally responsible for collecting evidence against the trade. Clarion was a founder member of the society for effecting the abolition of the slave trade in 1787. In Liverpool, William Rose was one of the best known abolitionists. He wrote poetry and pamphlets in favor of abolition. Opinion in Liverpool was generally pro-slavery and like other abolitionists, Rose tended to work behind the scenes rather than openly declaring his views.

The West India lobby of plantation owners and their supporters in the British Parliament fought abolition. Although ultimately unsuccessful, they gained 20 million pounds compensation for plantation owners for the loss of their slaves. Ex-slaves were not compensated. Despite the abolition of slave trading by Britain and other countries from 1807 onwards, illegal trading continued for a further 60 years. About a quarter of all Africans who were enslaved between 1 500 and 1 870 were transported across the Atlantic in the years after 1807. Much of this illegal trade was to the sugar plantations of Cuba and Brazil.From 1815 to 1865, the British Royal Navy undertook antislavery patrols off the West African coast, seizing hundreds of vessels. Britain was forced to pay compensation for seized ships and to encourage countries such as Spain and Portugal to abolish slaving. Although humanitarian considerations were important, economic interests were also at stake. Cuba and Brazil were competitors to British West Indian sugar production. Merchants developing the palm oil trade with West Africa, who were largely based in Liverpool, also feared illegal slaving would damage their interests.

Stages of Behavioral Change

Introduction In our day to day interactions, we encounter people and circumstances that require us to change our behavior. In other cases, we ourselves want to change our own behavior for personal reasons. There exist no standard procedures for behavioral change that can be used to govern the process through which individuals change their behavioral trends.Advertising We will write a custom essay sample on Stages of Behavioral Change specifically for you for only $16.05 $11/page Learn More However, some people have argued that individuals change their behaviors when the cost of not changing a particular behavior exceeds the cost of changing that behavior (Fieger, 2009). Through our own understanding of individual functioning, we can choose to change our behaviors without waiting for the negative impacts associated with the behavior to motivate us. Psychologists have developed various models and theories in attempt to describe various stages along a behav ior change continuum (FHI, 2004). The process of self behavioral change involves various stages as outlined by DiClemente and Norcross (FHI, 2004). The precontemplation stage involves individual’s recognition of an existing problem in order to make a decision to change the behavior (FHI, 2004). Contemplation stage is the stage where the individual acknowledges the problem and seriously considers changing it while preparation for action involves individual decision to change the specific behavior within a specified period of time (FHI, 2004). Finally, the action stage constitutes the ability of an individual to display consistency in the new behavior and maintenance which requires the individual to display the same consistency for more than six months (FHI, 2004). This is the general process through which individuals abandon undesirable habits and acquire new behavioral trends and it is also the model that forms the basis for therapeutic behavioral change. After having uncover ed that I spend approximately 3000 minutes talk time on my phone every month, I realized that I needed to change my behavior regarding phone use since my monthly phone bill was very expensive and my mother kept insisting on the side effects associated with cell phone use. In addition, I spent considerable amounts of time on my phone consequently promoting time wastage which negatively impacted on my school work. The radio frequency energy from electromagnetic radiations emitted through the antenna of mobile phones is believed to affect the brain and other head tissues (NCI, n d).Advertising Looking for essay on psychology?

Get your first paper with 15% OFF Learn More Numerous studies conducted to investigate the relationship between cell phone use and the risk of brain tumors reveal no increased risk with increase in call duration in some incidences while some studies suggested slightly increase risk for certain types of brain tumors as a result of increased cell phone use (NCI, n d). This perceived cancer threat was the major factor that motivated to change my behavior. Although I was reluctant at initial stages of the process claiming that the side effects of cell phones are non existent and if they were, my phone was adequately secure, extensive research on studies conducted on the side effects of cell phone as well as the need to reduce my monthly phone bill heavily influenced my decision and determination to cut off on my cell phone use. After acknowledging that excessive use of my cell phone was adversely implicating on my finances and may affect my long term health condition, I decided to undergo an eight week behavioral transformation process after which I would cut down my cell phone use by half. To ensure successful outcomes of the process, I sought information an advice from people who had a similar problem from where I acquired problem solving choices (FHI 2004). The people suggested the methods that they used to reduce the amount of time they spent on their cell phones which included the use of e mail and other social networks such as face book and myspace to interact with people rather than making phone calls. In addition, other people preferred sending text messages while others utilized face to face communication whenever it was possible. This information considerably promoted my behavioral changing process since I applied all these strategies through out the process and successfully managed to cut down my phone use significantly. Through out the process of behavioral transformation, I encountered various challenges that significantly hindered my ability to cut down on my phone use. Numerous interaction incidences required immediate feedback hence I preferred calling people rather than sending emails or messages to them as this may take them a longer time to respond. Further, my friends with whom we used to communicate for long durations of time using cell phones continued to ca ll me for long hours and it was difficult to convince them to similarly cut down on their cell phone use. In addition, since I had been used to the habit for a long period of time, the urge to make unnecessary phone calls persisted during the process and proved very difficult to fight it.Advertising We will write a custom essay sample on Stages of Behavioral Change specifically for you for only $16.05 $11/page Learn More At the end of the eight weeks period, I had managed to cut down my phone use by a considerable amount of time. Although I had not managed to achieve my target of reducing my phone use to 1500 minutes per month by the end of the period, I achieved an average 40% reduction in calling time upto 1800 minutes talk time in the eight week period which I intend to reduce further through continuous implementation of the strategies that I applied during the period of behavioral change. Since behavioral change is a continuous process, I am optimis tic that through dedication and commitment to change my behavior, with time I will be able to achieve my target and reduce the amount of time I spend calling on my cell phone for the safety of my health as well as financial status. Conclusion Behavioral change is largely motivated by an individual’s core beliefs which constitute the ideas that one believes to be true about him as well as the world as he conceives it to be (Fieger, 2010). Further, an individual’s attitude, which is the focal point through which he views the world, is highly informed by his values and principles establish the foundations of the individual’s identity and his conceptions of ideal behavior (Fieger, 2010). This is clearly evident in the process of my behavioral change which was highly influenced by the desire to live a healthy life and to manage my time and financial resources efficiently. Since I value my health very much, various health risks issues associated with cell phone use mo tivated me to reduce my cell phone talk time in order to diminish chances of developing such ailments. In addition, the general prevalence of time and resource management in the contemporary society further prompted me to change my behavior in order to conform to the society’s desirable values.
