What Is Charles Darwin's Theory Of Natural Selection?

1495 Words6 Pages

The theory of Natural Selection allows more individuals to be produced each generation that can survive. Phenotypic variation is hereditary. Those individuals with hereditary traits better suitable to the environment with survive. This mechanism known as natural selection, which can be identified as genetic change in a population emerging from differential reproductive success. Thomas Malthus. Charles Darwin’s contemporary at that time was concerned about the theory of natural selection with the population growth and the limitations or restrictions with the limited food supplies had on the size of the population. Charles Darwin and Alfred Russell Wallace realized that alike influences work in nature. Living creatures produce more offspring than can generally be expected to survive and reproduce. …show more content…

DeCorse, 2008, pp. 56-59). The theory of natural selection by Charles Darwin and Alfred Russell Wallace was accepted as the English parson Thomas Malthus published a book in 1797 called Essay on the principle of population. In the book published, Thomas Malthus was warning his fellow Englishmen about most of the strategies designed to help the poor were doomed because of the unceasingly intense pressure of the population growth. It was said that a nation would quickly double its population in the few years to come leading to extreme scarcity of food and a state of great physical and mental distress and discomfort (Berkeley, 2008). Charles Darwin’s theory of natural selection does impact today’s scientific thinkers. A whole field of evolutionary biology in founded on his work. It has been said that Charles Darwin’s influence can be felt in how the Christian orthodoxy that supported and justified most sciences, has fallen away and even in our understandings of human interactions, summed up by the phrase

“Population, Sustainability, and Malthus: Crash Course World History”, John Green examines one of the theories about the downfall of humanity, proposed by Thomas Malthus. Malthus wrote an essay on the Principles of Population to explain why at the time, population growth was steadily slow. John Green goes ahead to talk about how Malthus compared the poor to rabbits. Expressing that the same powers that constrained the population of rabbits would do likewise to poor people. Forces such as: predators, weather, epidemics and starvation.

In his acclaimed novel, “The Book that Changed America: How Darwin’s Theory of Evolution Ignited a Nation,” Randall Fuller explores the groundbreaking work of esteemed natural biologist Charles Darwin and his 1859 work, “On the Origin of Species by Means of Natural Selection.” He documents the work’s travels throughout America and its circulation among New England’s intellectual elite, focusing on the explosive reactions to its previously unimaginable claims; theologians, scientists, Transcendentalist philosophers, abolitionists, and pro-slavery apologists alike all had something to say about this new theory. Fuller’s brilliant interpretation of this cultural upheaval, using personal writings from the desks of intellectual giants, cements Darwin’s

Simon, and his take on overpopulation. According to the article, Mr. Simon argues that “ ‘humanity’s condition will improve in just about every material way.’... ‘whatever the rate of population growth is, historically it has been that the food supply increases at least as fast, if not faster.’ ... Because of improved health standards, birthing many children is not the survival imperative for families that it once was. In cramped cities, large families are not the blessing they were in the agricultural

His father, Amzi, was a religious fanatic, completely devoted to Christ. Amzi also believed his ancestry was remarkable, and after dedicated research on his lineage, he published History and Genealogy of the Davenport Family, tracing back to England in 1086. This is likely one of the factors that lead to Charles’ later interest in eugenics, the idea of an ‘extraordinary stock.’ Despite Amzi’s complete devotion to his faith, as Charles grew, he strayed from his father’s beliefs and became immersed in the world of natural science. He attended Harvard and in 1892 earned his Ph.D. in biology.

As geology strongly proclaims that each piece of land has undergone and will continue to undergo great physical changes, we may expect to see changes amongst organisms that would be varied under the influence of nature, in the same manner as they generally would have under the changed conditions of domestication. Second to that if there were to be any variability in nature it would be a product of the unaccountable fact of natural selection or survival of the fittest. It has often been stated that the amount of change within nature is strictly, meaning that organisms and plants can only undergo a certain amount of change at any one time. Modern day man is able to act on external characters and can produce a great result within a short period

Spencer's work also served to renew interest in the work of Malthus. While Malthus's work does not itself qualify as social Darwinism, his 1798 work An Essay on the Principle of Population, was incredibly popular and widely read by social Darwinists. In that book, for example, the author argued that as an increasing population would normally outgrow its food supply, this would result in the starvation of the weakest and a Malthusian catastrophe. According to Michael Ruse, Darwin read Malthus' famous Essay on a Principle of Population in 1838, four years after Malthus' death.

However, the truth-claim of Malthus’s essay remains in the eye of the beholder. One may assume that the decline in population growth means that we have already passed the precipitous point of no return, at which humans have gone too far in their overpopulation to continue life as we know it, but one may also hold reasonable doubts about the existence of such a point. But regardless of one’s interpretation of modern population challenges and whether or not one believes Malthus’s theories to be true, the fact remains that An Essay on the Principle of Population set forth economic theories previously unheard of by the general population. Malthusian economics still poses questions that have had and will continue to have major importance in the coming years, regardless of whether that importance is simply theoretical or

It is talked about today that Darwin discovered the theory of evolution. Darwin's theory of evolution stated that individuals within a species vary from one another, variation is in some part heritable so that variant forms have offsprings that resemble them, and that different variants leave different number of offspring. Darwin then proceeded to elaborate on the mechanism of evolution by suggesting that in the universal struggle for life, nature "selects" those individuals who are best suited (fittest) for the struggle, and these individuals in turn reproduce more than those who are less fit, thus changing the composition of the population. In addition to natural selection, Darwin also suggested that species also evolve through the complementary process of sexual selection. According to Darwin, in sexual selection, one gender of a species develops a

Natural Selection is the long gradual process in which Biological traits either become more or less common in a population as a function of the effect of inherited traits on the differential reproductive success of organisms interacting with their environment. In Darwin’s work The Origin of Species he also mentioned evidence for the Theory of Evolution from his voyage around the world on The H.M.S. Beagle. The Origin of Species is probably the most influential work on evolutionary biology. The Origin of Species will help prove my thesis because it introduces the ideas that we base on evolutionary biology today.

In this book, Darwin emphasized that natural selection is the major element of his theory, since it elucidates the connection between variation and the evolution of a species. Borrowing ideas from the theory of exponential population growth by English cleric and scholar Thomas Malthus, he argued that the chance of infinite growth of population sizes is dependent on the geography and natural resources. If these are limited, an infinite number of organisms will not be permitted to survive. As a result of limited food, water, shelter, and other resources, species must struggle for their existence and compete for their survival. According to Darwin, this will decide which species will survive and which will become extinct.

He then presents his idea that is more fundamental than Darwinian natural selection. Instead of looking at life from the perspective of individual organisms battling for survival, Dr. Dawkins hypothesizes that everything in life has to do with a battle for survival of the genes. He claims that the reason for life is to ensure the survival of DNA. He supports this hypothesis by comparing the cheetah and the gazelle. He notes that the cheetah has been designed to hunt

. Thomas Robert Malthus can be acknowledged to have laid the foundation and paved the way to future theorists interest in the subject of population growth being a major problem with dire consequences such as poverty and misery. Extensive research on the topic has been done thereafter and a great deal of the theorists concluded that population growth is a problem but moreover it can potentially hinder development as more people equate to a higher demand on resources, services, food and employment. These findings were especially directed to the developing countries as they are characterised as being grossly overpopulated and developing notably slowly. It is important to note that for every view or argument, there is a counter argument.
