The Theory Of Natural Selection

Natural selection is the key to evolution. The difference in genotype from generation gives rise to key traits that help species survive and flourish. When these species reproduce, they pass on their genes to their offspring who then will be able to survive. Those species who don’t have these key traits reduce in number because they don’t possess vital traits that can help them survive nor can they pass on vital traits to their offspring. Charles Darwin was the person who came up with this theory and he discussed it extensively in his book The Origin of Species. This theory explains why we have so much species with distinct traits but what it doesn’t explain is the evolution of neuter individuals. Neuter individuals can’t reproduce so if they had any trait that gave them a foothold over nature, it cannot be passed on to another

Life is evolution. Humans continuously try to keep up with the latest trends in an attempt to remain relevant in society. In the past ten years, humans have evolved immensely with the introduction, development, and integration of technology into their culture. Virtually everything can be found on the internet. Pictures and documents are being shared through cloud storage rather than being shared directly with a physical document, and doing homework online is now the norm. People have adapted to the new age, and those who have not adapted are being left behind--this is where the theory of natural selection meets modern cognitive science. Steven Pinker, the author of How The Mind Works, argues that the concept of natural selection is not as linear as society may think it is with today’s information. There is more to evolution than straightforward “survival of the fittest”. Using his background knowledge in cognitive science and the social sciences, Pinker links the biological approach to evolution with his cognitive science approach in an attempt to generate a new perspective to the theory of evolution. Steven Pinker supports his claim that the concept of natural selection is more than a simple biological adaptation, but rather a combination between biological adaptation and an adaptation to the “cognitive niche”, with historical observations, analogical evidence, and exploitation of archaeological evidence.

Natural selection is most often used in the area of the natural sciences, but can apply to other fields. The knowledge question, how does knowledge develop over time? will be explored within the context of history and the natural sciences. Natural selection will be defined, in the context of this investigation as, knowledge progresses as evidence is discovered and verified. Thus the theories that have persisted in a particular subject are the most accurate ones, supported by plentiful evidence.

Evolution in terms of biology is defined as decent with modification and can be explained by the rise in diversity from generation to generation based on changes in the gene frequency. When changes occur in an individual’s genome, known as mutations, they give the individual different characteristics that can have a negative, positive, or neutral effect. If the mutation better adapts the individual to the environment, that mutation can be passed onto a new generation. If the mutation weakens the individual to the environment, that mutation will not be able to withstand multiple generations through progeny. This mimics Darwin’s theory of natural selection, which states that the individuals best fit to the environment have a higher survival and reproductive rate. Over time, these mutations contribute to genetic variation within species (yourgenome).

Although Charles Darwin’s theory of natural selection was a marked departure from his predecessors, it was neither built alone nor stands alone. His 1859 work, The Origin of Species, grew from theory that had been advanced by naturalists before him and was in turn incorporated into genetic evolutionary theory, among others (Frisancho). Similarly, the term natural selection encompasses Darwin’s conditions for it to occur, how it is measured, and how it is related to evolution. This information can then be used to understand how it relates to humans.

Darwin was born in England and is most famous for his work on natural selection. He brought about the idea that all species of life have evolved over time from common ancestors. This process involves favourable traits participated in the process and became more common in successive generations of living things. At the same time, unfavourable features became less common. He presented compelling evidence from his detailed research that included a five-year voyage on the HMS Beagle, besides developing the idea of natural selection.

Although up into the nineteenth century it was common belief that a divine being created life, life has evolved since its first appearance about 3.8 billion years ago. Darwin claimed in his book, On the Origins of Species published in 1859, because “ ...many more individuals of each species are born than can possibly survive; and as, consequently, there is a frequently recurring struggle for existence…” small variations that occur in the mutation of genes and genetic recombination during reproduction. Some of these variations are bound to be better suited to their environment and will succeed. Those that are less favorable are bound to fail. This is a process called natural selection. This genetic advantage increases the likelihood that the

When Charles Darwin presented his theory of natural selection in On the Origin of Species he was aware that it would not easily be accepted. Darwin compares the struggle he anticipates to the challenges encountered in other scientific fields, writing, “The difficulty is the same as felt by so many geologists, when Lyell first insisted that long lines of island cliffs had been formed, and great valleys excavated, by the slow action of the coast-waves” (Darwin, 392). Darwin anticipates that his theory will be criticized in a similar manner to theories purposed by Lyell. Believing that these criticisms originate from the limitation of human understanding. Among these limitations is the opinion that natural selection has the same restraints as the selection practised by humans during domestication. Natural selection can improve all characteristics of an organism allowing it to adapt perfectly to its environment while human selection can only alter the visible appearance of animals for humanity’s benefit. An additional human limitation that must be overcome is the inability to understand the immense periods of time that Darwin associates with the variation between species. Darwin is critical of a human’s ability to comprehend such time frames, and as a result, worries they will dismiss his theory without understanding it. Darwin is aware that the reader must overcome the human limitations to understand the true capabilities of nature, and the vast quantities of time that are

According to history, Charles Darwin is the first scientist to frame the theory of evolution by natural selection. It was publish in his book title "On the Origin of Species 1859”. Darwin express the theory of evolution by natural selection as a process by which species change over a period of time. This change take place because of the changes in genetic and behavioral traits. The ability of the organisms to change over time or adjust to fit environmental factors is due to the ancestral trait. The evolutional theory was supported by great body of evidence from various scientific disciplines.

Natural selection is how animals evolve over time and develop traits that help them survive in their environment. Darwin's theory was directly related to psychologist William Jame's ideas of functionalism which was that different behavioral traits get passed down through their heredity or through learning from a prior generation. The study of heredity was still in early phases he believed that they could be passed down from human to human genetically. (Ciccarelli & White, 2015, p. 8) Both James's and Darwin's theories would mean that as people and animals adapt the genes that create a specific weaker traits begin to make the holders of those genes die out over time, until the gene is completely removed. This is why people use the term selected

Charles Darwin was the creator of Darwinism which is, “the theory of evolution by natural selection” (Junker 1). In school we are often taught that natural selection is survival of the fittest or the strongest wins. What seems to be a simple topic is actually one of the leading theories on the side of evolution in the highly controversial debate on Darwinism vs. Creationism. Darwinism states that certain genes in a population change through individuals. These “strong” genes are then produced more and are better able to survive making them the fittest. According to natural selection this process of evolving “usually takes place over many years, but in fast-breeding organisms it can occur rapidly, for example the spread of antibiotic resistance in some bacteria” ("Natural Selection” 1).

The jurisdiction of psychopathy is a terrifying disorder. Sufferers often develop antisocial behavior, marked by maladaptive personality traits. For centuries, many causes behind this disorder have been speculated, but the etiology remains inconclusive. There are three mainstream etiologies presented today, however they consist of biological, environmental, and social factors which may be equal in support. If the rise of psychopathy develops from biosocial conditions, is there an effective treatment and therefore cure for an adult psychopath? There is vast and varied literature which attempts to explain every detail about this confounding disorder.

Natural selection, a term often used in relation with the concept of evolution. Being as such, ones’ perspective is often led to take sides on a matter that they know little about. One side states that such a concept is full of lies and seeks to throw you from the path of belief. The other says that it proves that man came from a simpler being and that the supernatural is non-existent. Being someone of Christian faith, I was led down the path of the former. It is in my nature, however, to not blindly accept what someone has told me on the sole basis that it is what they believe. So I looked for myself, to come to my own understanding, and what I found led me to reconsider everything I had learned that had fallen onto this “two-path system.”

Psychopathy has been a growing topic in psychology in the past several years. Studies and research wonder what is the cause for this behavior, how does the disorder develop, and how it is linked through genetics. Since psychopathy can be linked to genetic traits these individuals are more dangerous compared to those who are labeled sociopaths. Environmental factors also play a role in the behavior of psychopaths, but in different ways since antisocial tendencies are developed. But the notion that genes play an important role are still being widely accepted and continues to the present day to remain a controversial topic. What is known is the behavior in psychopaths are not just passed down genetically because socialization is a key aspect for psychopathy development, environmental factors play a part in psychopathy, and antisocial behavior is an indicator of psychopathic tendencies.

Darwinism is a theory developed by Charles Darwin with the help of many others. It states that natural selection is the most common cause of evolution. All species of organisms arise and grow through the natural selection of inherited variations that help increase the individual's ability to survive and reproduce in its environment.
