Mankind posses a unique intellect that sets apart our species from other organisms on the evolutionary timescale. However, our extensive knowledge can come with consequences. Humans have the power to influence the evolution of virtually all other species in the world. Humans are capable of so much, such as extreme good and extreme evil. If the evolutionary clock was to be rewound, the chances of the first living cell evolving into similar modern humans that inhabit the globe today would be less than 0.01%.
They adapt to mankind’s defences to generate more breeding grounds of MRSA in humans and animals to generate growth. Genetic variation does not have to occur randomly as plasmids can transfer segments of DNA to distantly related organisms. Any inherited, genetic change in a population which takes place over several generations is defined as Biological evolution. Darwin and Lamarck have contributed majorly to the evolutionary theory. Although Lamarck’s theory was unsupported, he probably provided inspiration to Darwin and many other enthused scientists.
He claims that the breeders of animals and plants have had a profound impact with the changes they created among domesticated species. Darwin used the common practice of breeding animals as a way to introduce artificial selection in order to help the readers of 1859 understand the possibility of nature also being capable of producing similar changes through the same selective process. Darwin is firm that his theory of variation and inheritance plays a vital role in human reproduction. However, these kinds of ideas were treated as absurd as there was no direct evidence at the time that supported the belief of genetics. The idea was that people were made up of genetic variables and that each gene would be passed on as a unit to the next generation.
The process of natural selection supports the idea of survival of the fittest and plays a key role in evolution. For species to evolve, there must be diversity present. When diversity is acted upon, a mutation happens. Mutations are alterations that happen in the genes, or the result of genes not being able to copy themselves properly. At first, mutations may seem almost non-existent to the eye, but over time the mutation will become more visible.
Charles Darwin changed this though, when he studied and published his book, “The Origin of Species by Means of Natural Selection or the Preservation of Favored Races,” on his explanation of evolution through natural selection. After Darwin, many scholars followed in his footsteps to explain further theories. As technology advanced, there were more explanations for the concept of evolution followed by evidence and data because of the technology available to us. Without Darwin and technology, evolution would not be at the understanding that it is today. Charles Darwin came up with the theory of natural selection that caught the public’s attention due to its opposing ideas from other scientists of his generation.
The aim of science is to reach an exact truth of the world. The second attribute is that scientific realism is epistemic. To accept a theory one must believe that it is true. Van Fraassen acknowledges that a “literally true account” divides anti-realists into two camps. The first camp holds the belief that science’s aim is to give proper descriptions of what the world is like.
Charles Darwin, the “Father of Evolution,” inadvertently laid the foundations not only for life and science as it is known today but also for the concept of human nature and questions of its potential framework. After Darwin’s discoveries, many other researchers lay claim to the role of genes and heritability in nature. Some researchers assert this role of genetics in human nature, labeling it as a necessity in the development of a complete understanding, whereas other researchers deny genetics’ role in human nature entirely, claiming it to be a hindrance for scientific and social advancements. However, the novel Life of Pi by Yann Martel and the play Copenhagen by Michael Frayn show that human nature may be based not only on genetics but also on external factors. But what are the true differences, if any, between the impact of genetics and the impact of culture on the human being?
Darwin writes on how a species will adapt to its environment given enough time. When an animal gains a genetic edge over its competitors, be they of the same species or of another genus altogether, the animal has increased its chance of either procreation or adaptation. When this animal has this beneficial variance, the advantage becomes his and because of this, the trait is then passed on to the animals offspring. The theory of natural selection is not limited to inheritable and beneficial variations of a species. It also relies a great deal on the population growth and death of a species.
The term natural selection was one used by Charles Darwin, a well known naturalist that came up with the Theory of Evolution. The term natural selection is very crucial to evolution, it is the process in which certain species adapt to their environment by breeding with other members of that species that carry certain traits that help the species’ ability to survive . Darwin coined the phrase “survival of the fittest”, which talks not about how fit a certain organism is needed to be in order to survive, but how a species needs certain characteristics which help the population survive in a certain habitat or ecosystem. Natural selection is widely accepted by groups of scientists as the explanation for adaptations in evolution (Grabianowski, science.howstuffworks.com). While most look at natural selection throughout other organisms, humans themselves have adapted throughout history and are still evolving through natural selection.
Darwin’s concept on humanity initially begins with evolution. In order for the cogs in the wheel of nature to turn, there must be significant differences within species. Darwin refers to this idea as variation, which can be found within the aesthetic, behavior, or genetic makeup of an individual found in a species. These variations generate competition within species to survive, seeing as there will ultimately be both favorable and unfavorable traits. The concept of survival of the fittest is notably known as Darwin’s natural selection theory.
