Since ancient times, and even as recent as one hundred years ago, science and technology has allowed the human race to ‘evolve’ at an increasingly rapid pace. Some things that an average person would use today without thinking twice would most likely be unfathomable to an average person in the early 20th century. The evolution of science has especially affected medical care, a person can be taken to the hospital, have a faulty vital organ replaced, and assuming there were no complications, walk out within the span of about a week. The study of biologies has not only led us towards better health, it has also gained people the knowledge of genetic code, otherwise known as DNA or ‘Deoxyribonucleic Acid’. DNA can be thought of a cell’s blueprint, or instructions as to what it should become and what it’s duties are. Scientists have discovered that they can manipulate and change the DNA of an organism’s cells to make it deviate from the original ‘blueprint’, however one cannot interfere too much, as too much deviation from the original DNA can often lead to the the death of the organism. Aside from modifying DNA, researchers are also able to obtain a copy of a certain organism’s DNA and then use that DNA to create an exact copy of that organism. This is what is known as cloning.
A clone is an organism that is produced asexually from a single ‘parent’ to which the clone is genetically identical. Since it became quite popular in 1997 when Dolly the sheep was announced, there has been much discussion over the ethics and the benefits of being able to clone. There are two ways in which cloning can happen, called artificial embryo twinning, and somatic cell nuclear transfer, the former being a much older method of cloning. When an embryo spl...

...either by splitting an embryo in its early stages, or by replacing the DNA of an egg. Cloning has a rich and extensive history, reaching as far back as the 1880s, and if horticulture practices are counted, even hundreds of years further back. Cloning can happen in two ways, either an embryo in its early development stages has its cells split away from each other creating individual cells and then those cells are allowed to develop on their own; or the nucleus from another cell is placed into an egg cell that does not contain DNA. It has many benefits and research in stem cells is bringing humans closer and closer to advanced medicine. However many would argue against it, some saying that it is immoral to tamper with nature, others worry that cloning might end up in the hands of someone who intends to use it as something like a vehicle or device for world domination.

Evolution Applied to Human Health and Medicine Essay

- Evolution is defined as a gradual process in which organisms become better adapted to their environment through gradual changes that occur from generation to generation. Throughout the history of life, the human species has changed to become better suited to the environment. All of the changes have ultimately resulted from mutations, which occur at the gene level. Pathogens such as bacteria or viruses that live inside of our cells have had a major influence upon our evolution (Parks, Panelli & Weinstein, 2003)....   [tags: Science / Evolution]

Charles Darwin 's Theory Of Evolution Essays

- Charles Darwin No one could have predicted the profound impact of Charles Darwin’s five-year trip aboard the HMS Beagle, and how his discoveries would change the lens through which we view the world. Not even Mr. Darwin himself was yet aware. As he studied the specimens of the creatures he brought back from this expedition, one question after another would propel him forward in developing his theory of evolution. But in the beginning, he could not grasp the implications of what he had discovered, and how it would change our perception of the origin of life on Earth....   [tags: Charles Darwin, Evolution, Charles Lyell]

Essay on Why should medical editors CARE about case reports?

- „Always note and record the unusual…Publish it.“ (1) -William Osler While contemplating the evolution of medical publishing, one might be tempted to think of it under terms of the Recapitulation theory. Namely, as ontogeny recapitulates phylogeny, similarly it might be conjectured that both evolution of medical publishing, at least in its forms, and the stages of scientific production in a clinicians` career follow similar progression of evolutionary stages. In other words, a modern „evidence-based“ clinician, trough his publications, climbs the steep „Level-of-evidence“ pyramid, recapitulating much the growth of the pyramid itself; during his first clinical steps, he writes case report...   [tags: Record Keeping, Medical Novelty]

Essay on The Relevance of Evolutionary Theory in Biomedical Science

- Evolution has been arguably one of the largely discussed topics in the advanced institution of science. The theory of evaluation, first presented by Charlies Darwin (1990), states that all biotic organisms were developed and advanced from primitive organisms through gradual changes occurring over time. The relevance of this fundamental theory is witnessed throughout the disciplines of the pathology department in the subject area of biomedical science. Biomedical science consists of seven major disciplines; hematology, transfusion science, clinical chemistry, histology, virology, cytology, immunology and medical microbiology....   [tags: evolution, biotic organinisms, primitive organisms]

Is There One Science, Western Science? Essay

- 1. Introduction The period known as the Renaissance, brought with it a paradigm shift on perceptions of causality and to how phenomenon was viewed. It was this European Enlightenment that radically departed from the traditional religious metaphysical views of cause to one which relied on rationality and the empirical as the foundation of cause. This approach was more useful to practical everyday life than the traditional metaphysical way of thinking. The empirical way of explaining phenomena, events and observations expressed in quantitative measurement, offered more readily acceptable explanation of cause than the traditional metaphysical way of thinking employed up to this time....   [tags: renaissance, enuropean enlightment]

The World Of Science And Medicine Essay

- Accompanied by Deborah Lacks, Rebecca explores the world of science and medicine in order to better understand the scientific perspective on Henrietta Lacks and HeLa. Given that Henrietta’s immortal cell line has played such a crucial role in the evolution of modern science and medicine, Skloot understands that her narrative account would be incomplete without consideration thereof. However, Rebecca also considers that the scientific knowledge of Henrietta and HeLa began to develop even before her death, and grew just as quickly as the cell line did, thereby proving one of the most thoroughly-developed and collected sources of knowledge about Henrietta....   [tags: HeLa, Henrietta Lacks, Rebecca Skloot]

The And Evolution Of The Advanced Practice Registered Nurse Essays

- The Nurse Practitioner Role: A Journey to Self-Actualization The history and evolution of the Advanced Practice Registered Nurse (APRN) role, particularly the Nurse Practitioner (NP), can easily be compared to the process of self-actualization. According to Webster’s dictionary (2015), to self-actualize means “to fully realize one’s potential.” Through the collaboration of many great minds and the practice of holism as the best approach for providing healthcare, the role of the APRN arose. Nursing leaders and advocates such as Thelma Ingles and Loretta Ford knew the potential and remarkable impact the APRN would have on the healthcare system and had the motivation and vision to set it in mo...   [tags: Nursing, Registered nurse, Health care, Medicine]

How Can Images Improve Medical Workflow? Essays

- How can Images Improve Medical Workflow. Images of human anatomy have been around for more than 500 years now. From the sketches created by Leonardo da Vinci, to the modern day Computed Tomography (CT) or Magnetic Resonance Imaging (MRI) scan, images have played a great role in medicine. Evolution in medical imaging brought together people from various disciplines such as Biology, Physics, Chemistry and Mathematics, a collaboration which has further contributed to healthcare as a whole. Modern day imaging improves medical workflows by facilitating a non-invasive insight into human body, accurate and timely diagnostics, and persistence of an analysis....   [tags: Anatomy, Diagnostics, Healthcare]

The Evolution of Nursing Essay

- Nursing has changed a great deal since the first nursing class graduated from Florence Nightingale's nursing school in 1860. The great advances in medicine over the last century have brought changes in the demands placed on nurses. Today, there are over 3 million registered nurses working in the United States alone, and these nurses cover a broad range of specialties and have a broad range of responsibilities (Bureau of Labor Statistics). A typical day for a registered nurse can range from being involved in a medical specialty to performing a specific task....   [tags: healthcare professionals]
