Topic > The Role of Natural Selection in Darwin's Theory of Evolution

The term natural selection was composed by Charles Darwin in the nineteenth century. It was the result of evolution that began through the creation of a variety of different species that evolved and developed over time. Species adapted through their characteristics and reproduced, passing on their genes to spread to others and improve their species. Since it is known as connoting natural selection, the term “survival of the fittest” is closely related to the idea of ​​the selection process. It is because of our heritage, our dominance, and our superiority over other species that we have allowed some to be the best. All species must struggle to survive so they can pass on their genes through reproduction. Much of this topic is what I will talk about in this essay. I will discuss the constitutions surrounding Darwin's theory of evolution and the extent to which natural selection plays an important role in establishing this process. Say no to plagiarism.

It involves much of the nature and nurture debate about what we inherit and how we adapt to our surroundings, for example. As we are born, we grow and develop, so Natural Selection is a gradual process that is calculated over time. In some ways we can't escape it, and some argue we don't have much choice in the matter. As I have already said, the event of Evolution was the beginning of Natural Selection. However, much of the concept of Adaptation and the terms surrounding it are the explanation of Natural Selection. Mainly because we were formed through this process, so we created ourselves or were born with idealistic attributes to assist in survival and to compete as part of a species. There are three types of adaptation created by Godrey. These are: Explanatory Adaptationism, Empirical Adaptationism, and Methodological Adaptationism. Darwin's ideas were highly accepted by biologists after the publication of his book “The Origin of Species” in 1859 in which he gained acceptance from them as it supported scientific knowledge. The theory of natural selection was co-created by Darwin and Wallace who encouraged the writing of this book. This term is based on how organisms are specified in a way that closely resides in the environment in which they live. An example of this would be a polar bear created from fur and almost always grown in extreme cold climates in countries like Antarctica. Natural selection solves this question, and we are all selected to be made a certain way and placed in an environment to which we adapt. The concept of Natural Selection is present everywhere, so it is powerful. The term Adaptation is actually a fundamental part of Natural Selection. It is based on the attributes that help the survival of the organism. The way it is built, formed and its behavior determine whether it is suitable for survival in its environment. Furthermore, as it evolves over time, the traits it develops are an important point for adaptation. Adaptive is not the same as Adaptation, it's more about how well you can adapt to these environments with your current fitness. While Stephen J Gould discourages this, he coins the term Exaptation which suggests that the fitness of groups of species was not originally selected for by natural selection despite being conducive to selection. They have parts of their anatomy createdfor different functions. For example, according to Gould, a bird's feathers are initially considered a feature for insulation purposes rather than for flight. “What the feather example shows us, then, is that exaptation is by no means an isolated shift, since it is preceded and followed by adaptation, nor is it a one-off event, since post-exaptation adaptation can lead to a subsequent exaptation”. Some attributes do not always imply that they are part of evolution, a developmental process simply because they seem more suitable as they might actually be known for various functions. Most of the ideas surrounding Adaptationism arise from concerns related to philosophy. The reason for the species and our selection process may be due to intelligent design. Darwin's ideas are similar to William Paley's clock analogy. The concept of “telos” meaning end or purpose implies that we are made for a reason and have a designer rather than a selection process. This equates to a supernatural creator which in terms of philosophical views would be God. The complexity of the universe can be supported by science. However, “this most controversial idea is the claim that apparent design has a special status as a biological phenomenon. A crucial point here is that selection can have this kind of central importance even if it is rare." The article on adaptation referred to discusses the views that through adaptation natural selection causes much of the effects involved in the world. Instead, natural selection must highlight this idea and be of much greater importance. Its constraints will be discussed later in this essay. Much of the concept of Telos leads us to question whether evolution is teleological. It is known that an organic world was born inorganically using the term “ex nihilio” which means that creation was made literally from nothing. However, through atoms, neurons, etc., we are transformed into matter to form organic materials. Mammals arose from non-mammalian ancestors, so nothing of natural origin has been discovered. For evolution to work we need three aspects; variation, reproduction and inheritance. Darwin initially based his theory on the fixity of species, but then changed his argument to Transmutation, also known as Evolution. The Malthusian lens is based on the struggle for existence meaning limited resources, therefore favorable variations spread through breeding to stay alive. The individuals of each species must all be different otherwise if we were all the same evolution would not work. Darwin used the installer's survival after adopting it from Spencer. We must all possess a distinction between ourselves since according to Malthus there must be a struggle for existence. Therefore, according to Spencer, there must be a struggle for existence. This concept was developed by Spencer, who agreed that there should be “survival of the installer,” which meant that the strongest and best genes would continue to live. His main views consisted of sociobiological progress. For him “all species tended towards a demographic equilibrium in which the lesser the individual's ability to survive and the lesser the need to reproduce. For the human species, Spencer diagnosed a temporary imbalance, since the capacity for reproduction was greater than required by the progress achieved in social individuation. The struggle for existence, based on social terms, will cause the demands of society to become a problem. There won't be enough for everyone and the growing population will eventually decline and become extinct. Those who survive will be thephysically better individuals, better genes. According to Darwin, we are involved in a process of progress and development that is axiological. Things seem to be getting better What Darwin calls a “little warm pond” is where all species originated. For humans to develop from this to come up with a theory like Evolution is remarkable. However, he believes that we cannot forget our origins, but that there are some types of progress. There is no telos and our life develops through the needs of the environment we are part of. This is because it puts in place a struggle for survival, so we must develop. Julian Huxley presents a critique of the concept that "a man is superior to a worm." Just because a man has the ability to think and is above everyone in the chain of being, man still possesses traits similar to other species. For example, an octopus's eye is identical to a human's. It contains a retina, a lens and a cornea, which means that the species can intercept characteristics and are not as different as we think. Huxley deciphers the complexities between the races. According to him we are all species adapted to a particular environment, so we cannot conclude that man is the best race when an animal adapts better to the surrounding environment. Their complexities are not as complex as those of other species since the complexities themselves are complex. Furthermore, Huxley argues that it is not possible for the best genes to survive longer. Simple organisms remained in existence and continue to survive. Darwin extends his vision to suggest that evolution is a slow-moving process and that we must progress by taking small steps. We need to know that something is changing in order to notice it. Otherwise, if everything were in constant flux, we would eliminate our perspective. As I mentioned briefly before, Gould plays an important role in natural selection. He believed it was important but not the most significant feature of evolution. He devised the theory of punctuated equilibrium which posed a challenge to Darwin's theory of evolution. It states the idea that evolution is not coherent and that it goes through uncertain changes. Written with Niles Eldrege, Evolution goes through various patterns and breaks. This implies that a new species can originate in an environment in which it must adapt to change. This raises questions about how adaptation works, especially if a species were to migrate to a different environment where it would have to adapt to a new place. According to the fossil findings there is no particular modification as there is no continuous effect of evolution. However, there are periods of stability. Gould believes that any sign of progress in nature is “really the random movement away from simple beginnings, not a direct impulse towards intrinsically beneficial complexity.” We all have complexities in certain ways, but we cannot afford to learn the same way or be born with identical traits, which means we will all become extinct. Morris creates an argument based on this idea by stating that the complexity of our brain converges as it continues to reappear, which implies, according to him, developments. Some species share similar traits that are distinct between vertebrates and non-vertebrates. This is a case of convergent evolution. The independent evolution of similar traits and ancestral conditions that are often closely related where different species respond to similar challenges. Morris agrees that this convergence is possible in biological terms as we see these forms reappear. Beyond that, Lewontin accompanies Gould in their Spandrels analogy. It is argued that the beauty of the spandrels in a Gothic cathedral is created for aesthetic purposes,.
