In reference to the evolution theories proposed by Lamarck (Lamarckism) and Darwin (Darwinism) the evolutionary of the MRSA is in controversy to which theory best supports it. Certain traits are aligned with both evolutionists as the MRSA have relatable characteristics that define the theories of Lamarckism and Darwinism. However, very few aspects relate to Lamarckism in comparison to Darwinism as the evolution of the MRSA sufficiently relates to the theory of Darwinism. As stated above SCCmec is the major gene that promotes resistance to all β-lactam antibiotics this acquired gene is present in many of the resistant S. aureus. As described by Lamarckian, theory of evolution states that organisms acquire changes that enable them to adapt in …show more content…
The theory commends that Darwinism is descending with modifications, defining that mutations and changes occur randomly and are not completely influenced by the environment. This effectively relates to the process of the MRSA as it portrays a genetic variation or mutation in cooperating the SCCmec unsystematically. This is a clear evidential mechanism that drives the evolution of the MRSA, through heredity and inheritance of genes these mutations are carried on by its offspring through ‘natural selection’ of these well adapted bacteria survival of these pathogens increase. As a result, the MRSA strongly reflect and relate to the theory of Darwinism as it includes characteristics that relate to the beliefs of the evolutionist. Thus, the theory proposed by Charles Darwin is the most effective and relatable theory to the Staphylococcus aureus. Darwin believed that the desires of animals have no effect on how they evolve, and that variations in an organism during its life do not affect the offspring. During his 5-year world voyage on the HMS Beagle Darwin observed and collected specific evidence that led him to propose a revolutionary theory called natural selection (“Best adapted”). This clearly explains the evolutionary of the S. aureus as it relates closely to the theory of genetic mutation and descend with …show more content…
There are certain concepts and theories that define evolution as a whole, proving themselves with adequate evidences that are discovered, supporting the theories of evolution. The key theories of evolution are Darwinism and Lamarckism that state two similarly factual perspectives, however Darwinism is the theory that is believed with prominent evidence that backs up its beliefs and representations. The theory states descend with modifications, which means that genetic mutations occur assisting the species to have genetic variations and specific changes, this mutation is then inherited by the offspring if it succeeds in surviving. This process is defined as natural selection. Comparatively, Lamarck’s theory outlines that the difference in use and disuse of certain organs and muscles develops variations in the population, followed by the inference of inheritance of the acquired characteristics. Thus, this evidently displays that Darwinism is the theory that best suits the Methicillin Resistant Staphylococcus aureus as it clearly defines its process of evolution replicating its characteristics to the theory of
Antibiotic-resistant bacteria are created when mutations in the pathogen's genetic code occurs, changing the protein in the bacteria that the antibiotics normally go after into a shape that the antibiotic can not recognize. The average bacteria divides every twenty minutes, so if a contaminated spot has one single bacteria in the morning, there could be trillions on that same spot at the end of the day. That means that when counting all the possibilities of mutations, the amount of mutated offspring that the bacteria might have formed during those replications could be as high as in the millions. Fortunately though, this does not happen so frequently that it is normally an issue. The amount of non-mutated bacteria vastly outnumbers the mutated ones and many of the mutations occurring in the bacteria usually have either a harmful effect, or not effect at all on its function. That means that the pathogen is still relatively less harmful than it c...
Evolution, also known as descent with modification, is a phrase Darwin used in proposing the evolution of Earth’s many species. Charles Darwin noticed that the descendants of ancestral species were different from the present day forms of species. Darwinism is a theory of biological evolution developed by Charles Darwin who was an English naturalist. He expounded the theory of evolution in his book of the Origin Species in 1859. He expresses that all types of organisms emerge and develop through natural selection, small, acquired traits that expands the individuals of capacity, survival, and reproduction. In this book, Darwin theorized that animals and plants evolve and develop with the aid of the creator through the process of natural selection.
This presents a potent example. With a pathogen like a cold, generation time is short, mutation rates are high, and genetic information can spread rapidly through a population. Therefore, evolution (a shift in gene frequencies within a population through time) can occur in weeks (as opposed to the slower pace most commonly associated with evolution). Evolution occurs via natural selection. Pathogens meet the requirements of natural selection by having variability of heritable traits which impact their reproductive success in comparison to others in the population. Consider the heritable and highly variable trait of virulence. Evolution predicts that those pathogens with high virulence must also have successful transmission when their host is
Darwin has two theories on the key principles of theory of evolution. One is the natural selection, a species that attains characteristics that are adapted to their environments (Darwin, Charles). The other one is survival of the fittest, which is when an individual best adapts to their environment survive to reproduce, and their genes are passed to later generat...
Anyone with even a moderate background in science has heard of Charles Darwin and his theory of evolution. Since the publishing of his book On the Origin of Species by Means of Natural Selection in 1859, Darwin’s ideas have been debated by everyone from scientists to theologians to ordinary lay-people. Today, though there is still severe opposition, evolution is regarded as fact by most of the scientific community and Darwin’s book remains one of the most influential ever written.
Keith Henson a writer in evolutionary psychology once said that “Evolution acts slowly. Our psychological characteristics today are those that promoted reproductive success in the ancestral environment.” Evolution was first introduced by a naturalist by the name of Charles Darwin. Darwin had written an autobiography, at the age of 50, On the Origin of Species (1859) explaining how species evolve through time by natural selection; this theory became known as Darwinism. “Verlyn Klinkenborg, who writes editorials and vignettes on science and nature for the “New York Times”” (Muller 706) questions Darwin’s theory in one of his essays he wrote called Darwin at 200: The Ongoing Force of His Unconventional Idea. Both articles talk about the theory of Darwinism, but the authors’ use different writing techniques and were written in different time periods. Darwin himself writes to inform us on what the theory is, where as Klinkenborg goes on to explain why Darwinism is just a theory. Today, evolution is still a very controversial topic among many. It comes up in several topics that are discussed everyday such as in politics, religion and education.
In 1859, a biologist named Charles Darwin postulated a scientific theory, which stated that all living organisms evolved through a process of natural selection. According to Stephen Hawking, Charles Darwin claimed that the offspring of a particular species gradually evolved themselves genetically to resist the changes in the environment (573). The theory contended that the organisms could adapt to the changes in the environment through the survival of the fittest. Though this theory is regarded as a breakthrough in the field of biological evolution, it is interesting to explore how this seemingly scientific theory has been suitably modified, and intellectually applied to both negative and positive aspects of life.
Charles Darwin has five parts to his theory of natural selection, firstly the “Geometric increase” which claims that “all living things reproduce in great numbers”, meaning that species may survive but not all will survive because, the resources used for survival for instance ,food will not be enough for all living things. “The struggle for existence” because there is a limited number of resources and can only sustain some and not all, not all living things will survive, however the question lies in which living being will survive?. “Variation” is the third part of natural selection which claims that within those living things there are variations within them that will determine whic...
Resistance first appears in a population of bacteria through conditions that favor its selection. When an antibiotic attacks a group of bacteria, cells that are highly susceptible to the medicine will die. On the other hand, cells that have some resistance from the start or acquire it later may survive. At the same time, when antibiotics attack disease-causing bacteria, they also attack benign bacteria. This process eliminates drug-susceptible bacteria and favors bacteria that are resistant. Two things happen, populations of non-resistant and harmless bacteria are diminished, and because of the reduction of competition from these harmless and/or susceptible bacteria, resistant forms of disease-causing bacteria proliferate. As the resistant forms of the bacteria proliferate, there is more opportunity for genetic or chromosomal mutation (spontaneous DNA mutation (1)) or transformation, that comes about either through a form of microbial sex (1) or through the transference of plasmids, small circles of DNA (1), which allow bacteria to interchange genes with ease. Sometimes genes can also be t...
The evolutionary theory is the concept that species evolve over time through the mechanism of natural selection of survival and reproduction. Natural selection means acting on the assumption that various living organisms were produced by genetic diversity and mutation. The evolution theory may also be referred to as the philosophizing science. This theory states that all phenomena are derived from natural causes and can be explained by scientific laws without reference to a plan or purpose.
Charles Darwin in his book, On the Origin of Species, presents us with a theory of natural selection. This theory is his attempt at an explanation on how the world and its' species came to be the way that we know them now. Darwin writes on how through a process of millions of years, through the effects of man and the effects of nature, species have had an ongoing trial and error experiment. It is through these trials that the natural world has developed beneficial anomalies that at times seem too great to be the work of chance.
Evolution is a systematic mechanism through which the modern day has evolved from his ancestors. The Darwin’s Theory of Evolution is based on the premise that we all
The theory takes into consideration the biological processes of natural selection, mutation, symbiosis, gene transfer and genetic drift. Science concept Charles Darwin Charles Darwin was a naturalist born on the 12th of February 1809 in England. Darwin grew up loving nature and went to Edinburgh University. On the trip around the world, Darwin collected natural samples including birds, plants and fossils. Darwin found a particular interest in the Pacific islands and South America.
Evolution is a complex process by which organisms change over time; it is a process in which traits are passed from one generation to the next (Darwin and Beer 1996:108-139). Evolutionists have tried to explain the loss of functions of different organs, for centuries. The two most prominent scientists that studied evolution were Jean-Baptist Lamarck and Charles Darwin. Lamarck’s theory of inheritance of acquired characters and Darwin’s variational evolution were the most important theories that attempted to explain evolution before the discovery of genes during the beginning of the twentieth century.
Biological evolution is the name for the changes in gene frequency in a population of a species from generation to generation. Evolution offers explanation to why species genetically change over years and the diversity of life on Earth. Although it is generally accepted by the scientific community, Charles Darwin’s theory of evolution has been studied and debated for several decades. In 1859, Darwin published On The Origin of Species, which introduced the idea of evolutionary thought which he supported with evidence of one type of evolutionary mechanism, natural selection. Some of the main mechanisms of evolution are natural selection, mutation, and genetic drift. The idea that all life on Earth shares a common ancestor has been around for a long time but has risen to significance in society over the last two centuries.
