Primate Evolution Essays - Diets, Primate, Dietary Fiber, Nutrition

Primate Evolution Variation in the choices of food on a daily, seasonal, and yearly basis is one of the greatest differences between primate species. Primate diets have generally been divided into three main food categories-fruit, leaves and fauna (including insects, spiders, and bird's eggs for the most part). The different diets also are referred to as Frugivores, Folivores, and Insectivores (fruits, leaves and insects respectively). These gross dietary categories are correlated with aspects of primate activity patterns such as home range and group size. There are different problems that have to be overcome in order to obtain a balanced diet on a day-to-day basis. New leaves and mature leaves, for example, may have different nutritional bases or availabilities. Some fruits appear in large clumps while others are spread thinly over a larger area. Aside from diet, primates have tended to either adapt through specialized dentition and digestive systems or rely on a variety of different foods. Those that chose this second route have tended to have larger brain sizes relative to their overall body size. This may be due to the need to know where different types of food can be found at different times throughout the year. Have you ever looked at a picture of a gorilla or money that has what appears to be a "beer belly" look? Those primates that specialize on eating large amounts of vegetation have difficulty digesting their meals. Different solutions have been found including double stomachs or multichewes, but the problem usually requires an individual to sit back and let the digestive system work-and on the die expel gas. It hasn't been until recently that it was realized that primates, who evolved in the canopy, actually had a quite difficult time finding adequate nutrition. Due to natural selection, which strongly favors those traits enhancing foraging efficiency, and this difficulty finding sustenance, the characteristics regarded as belonging to primates were evolved. Most primates species either maximize the efficiency of their digestive track or maximize the quality and the volume of food processed in a day. Also. Those species, which increase the volume of food, consumed also tended to have larger brains because of a need to remember, not only what, but also where good food sources are and when they are in season. Knowing the trends of evolution, the next thing to do is to look at how it relates to humans. It can be seen that out closest living relative, the chimpanzee makes up 94% of his diet with plants. Most of this is fruit with high sugar and fiber content, meaning that chimps take in hundreds of grams of fiber per day; contrary to the 10 grams or less the advantage American consumes. This suggests that our diet should be higher in vitamin C, pectin, and fiber like our relatives in the wild. Ironically, the same natural selection, which favors the most energy-dense and low fiber diets, may now be causing us to suffer from too little fiber. Plants have been a major food eaten by primates. The primates were almost exclusively herbivorous. A strong focus on plant foods is characteristic of all primates-- and there is strong consensus that the primates were very strongly herbivorous (Milton 1987, 1993). Many plants are lacking vital nutrients, such as vitamins and the protein building blocks known as amino acids, that the monkeys and other animals require. Some plants lack enough carbohydrates to make them worthwhile as energy producers. Yet in all of these cases the primates would still search for specific plants that exhibited one or more of these traits, rather than just rely on the plant life that was within easy reach. The fact that the primates would make an active search from a variety of plants. One particular type of plant may have lacked was often complemented by the positive aspects of another plant. For example, fruits are low in fiber and protein and yet they are rich in valuable carbohydrates. If the primates had relied solely on eating fruit then they would have lacked sufficient protein and vital amino acids. To make up for that particular type of shortage, the monkeys eat certain leaves that are high in protein and fiber and that are also more abundant than the fruit. Together, the fruit and the leaves make for a much balanced diet for the primates. In order for the primates to rely on just one particular type of plant as a food source, the primates would have to travel quite a distance to obtain enough food from multiple trees of

Euthanasia is the Wrong Way to Go.

Euthanasia is the Wrong Way to Go. Euthanasia is the Wrong Way to Go.Do you believe in miracles? Does everything always turn out to be the way we perceive them? Does sickness always lead to death? With the use of Euthanasia and physician assisted suicide, yes it does. Euthanasia is the practice of putting terminally ill people to death painlessly, cutting their life short of the possibility to recuperate. I feel that in this case a medical license does not differentiate a doctor from a murderer. Assisting in ones death is immoral, unethical and should not only be a crime, but it should be viewed as premeditated murder rather than assisted suicide. Euthanasia is a shrouded killer and the physician that assist in the practice of it is no more then its sidekick.For instance, if you follow the work of Dr. Jack Kevorkian and those in which he helped to execute you will understand my theory.English: Raffi Hovannisian speaking at UCLA's "An ...Kevorkian's role in assisting suicides made controversial headlines all around the world. Kevorkian made a machine that would allow terminally ill patience to end their life with the touch of a button. He created the Thanatron its Greek for "death machine." The Thenatron released an anesthetic and then a lethal injection of potassium chloride that goes through the veins. Potassium chloride is a chemical that causes the heart to stop beating. The government uses this same chemical for executions by lethal injection. Kevorkian started gaining popularity because of his new death machine. In 1989 a 54-year-old woman with Alzheimer's disease named Janet Adkins, got in touch with Kevorkian and asked for his assistance. Adkins became the first person to die using the Thanatron. After Adkins's death prosecutors in Oakland County, Michigan, charged Kevorkian with murder. However a judge eventually dismissed the charges, but the judge prohibited Kevorkian from using...

Employment Law for Business Today and Tomorrow Research Paper

Employment Law for Business Today and Tomorrow - Research Paper Example The employment laws came into being as a result of the untiring struggle of laborers for the better working conditions, wages and their right to raise through trade unions and to present a charter of demands to the management when due. In order to strike a balance between the employers and the employees, the positive role of the trade union cannot be ignored. It is a matter of fact that without the cordial relationship between the employees and the employers, running the affairs of an organization smoothly is a big question mark (Deakin & Morris, 2005). The infrastructure of employment law around the globe is more or less the same in terms of rights and obligations of the employees and the employers. The rights and obligations of the employees and the employers are implemented through a contract of employment (Deakin & Morris, 2005). ...In many countries of the world, minimum wages of the employees are determined by their respective governments. We may cite here the example of Sweden where minimum wages are negotiated by the Collective Bargaining Agent on behalf of the employees with the management, keeping in mind the profitability of the organization/other factors. The CBA strives hard for a better deal for the benefits of workers (Deakin & Morris, 2005). Here we can mention the minimum wage laws that were introduced in different countries seriatim: USA (1938); Brazil (1940);Â  India (1948); France (1950) and last but not the least, UK (1998). Today 18 out of 25 members are part of the European Union where minimum wages for the workers are in vogue (Deakin & Morris, 2005). While looking back at the era of the Industrial Revolution, we observe that at that time workers were forced to work approximately up to 14 hours or even longer. Along with adult employment, children employment was also common with drastic features. In England, children had to work 8 hours a day in the textile factories. The Factory Act of 1802 and subsequent acts addressed the issues rela ted to children employment and the minimum working hours of an employee. According to the said act, the racial and sexual discrimination is unacceptable and considered illegal (Selwyn, 2008). The subsequent employment act, which came to surface in 1938, set a maximum of 44 hours and later on 40 hours a week. Even the immigrant workers are benefited from the mentioned act. There are areas where this act is not implemented. For instance, in the agricultural field, working hours can be spanned to 72 hours a week in the harvesting season.
