The Theory of Evolution The theory of evolution is based on the idea that certain traits are passed on more often than others. These traits make it easier for individuals to reproduce and survive which is why they tend to increase in number over time. Scientists have a better understanding of how this process operates. A study of the clawed-frog showed that duplicate genes can serve different functions. The process of evolution occurs naturally Natural selection is the process that results in organisms evolving to be best adjusted to the environment they live in. It is one of the main mechanisms of evolution along with mutations as well as migrations and genetic drift. People with traits that aid in reproduction and survival are more likely to pass these characteristics onto their children, resulting in gradual changes in the frequency of genes over time. This results in new species being formed and existing species being altered. Charles Darwin developed a scientific theory in the early 19th century that explains how organisms developed over time. The theory is based on the idea that more offspring are created than can be sustained, and that these offspring compete for resources in their physical surroundings. This results in a “struggle for survival” where those who have the most advantageous traits prevail while others are eliminated. The remaining offspring transmit the genes for these beneficial traits to their children which gives them an advantage over other members of the same species. Over time, the population of organisms possessing these beneficial traits grows. It is, however, difficult to understand how natural selection can create new traits if its primary purpose is to eliminate inequities individuals. In addition that, the majority of natural selections are used to reduce genetic variation in populations. Therefore, it is unlikely that natural selection will create new traits unless other forces are in play. Mutation, drift genetics and migration are three main evolutionary forces which change the frequency of genes. These processes are accelerated by sexual reproduction and the fact that each parent transmits half of its genes to each offspring. These genes are known as alleles and can have different frequencies in different individuals belonging to the same species. The frequencies of the alleles that result determine whether the trait will be dominant or recessive. In simplest terms it is a change in the structure of a person's DNA code. The change causes some cells to develop, grow and develop into an individual organism while others do not. Mutations can also increase the frequency of the existing alleles or create new alleles. The new alleles are transferred to the next generation and become dominant phenotypes. Evolution is based on natural selection Natural selection is an easy process that alters the populations of living organisms over time. It involves the interaction of heritable phenotypic variation and different reproduction. These factors create a situation in which individuals with beneficial traits survive and reproduce more often than those who do not have them. Over time this process results in changes in the gene pool, making it more closely matched to the environment in which they live. Darwin's “survival-of-the best” is built on this idea. This process is based on the notion that people adapt to their surroundings by displaying various traits. These traits increase the chance of individuals to live and reproduce, as well as produce a lot of offspring. BioMed Central states that this will eventually lead to the trait to spread across the population. Eventually page of the population will have the trait, and the population will change. This is known as evolution. Those with less-adaptive characteristics will die off or be unable to produce offspring, and their genes will not survive into the next generation. As time passes, genetically modified organisms are likely to become dominant in the population. They may also develop into new species. However, this is not an absolute process. The environment could change abruptly, causing the adaptations to be obsolete. Sexual selection is another factor that influences evolution. Some traits are favored if they increase the chances of a person mating with someone else. This can result in bizarre phenotypes, such as brightly colored plumage of birds or the oversized antlers of deer. These phenotypes might not be useful to the organism however they may increase the chances of survival and reproducing. Some students also misunderstand natural evolution due to confusion it with “soft inheritance”. Soft inheritance is not necessary to evolve, but it is often an important component. This is because it allows for the random modification of DNA and the creation of new genetic variants that aren't immediately useful to the organism. These mutations become the basis on which natural selection acts. Evolution is based on genetics Evolution is a natural process that causes changes in the traits inherited of a species over time. It is influenced by a number factors, such as mutation in gene flow, gene flow and horizontal gene transfer. Evolution is also influenced the relative frequency of alleles in a population's gene pool. This allows the selection of traits that are advantageous in new environments. The theory of evolutionary change is a fundamental concept in biology and has profound implications on our understanding of life. Darwin's theories, along with Linnaeus notions of relatedness and Lamarck theories of inheritance, changed the way that traits are passed from parent to child. Instead of parents passing on inherited traits through use or misuse, Darwin argued that they were favored or disadvantageed by the conditions in which they lived and passed that knowledge on to their offspring. He called this natural selection, and in his book The Origin of Species he explained how this could lead to the creation of new varieties of species. Random genetic changes, or mutations occur in the DNA of cells. These mutations can cause a variety of phenotypic traits such as hair color to eye color, and are affected by many environmental variables. Certain phenotypic traits are controlled by multiple genes and some have more than two alleles, for instance, blood type (A B, or O). The combination of the Darwinian ideas about evolution and Mendel's ideas about genetics is known as the Modern Synthesis, and it is the framework that combines macroevolutionary changes in fossil records along with microevolutionary processes, such as genetic mutation and the selection of traits. Macroevolution can take a long time to complete and is only evident in fossil records. Microevolution is, on the other hand, is a process that occurs much faster and is visible in living organisms. Microevolution is triggered by genetic mutation and selection which operate on a smaller scale than macroevolution. It can be enhanced by other mechanisms, like gene flow and horizontal gene transfer. Evolution is based upon chance The idea that evolution happens through chance is a claim that has long been used by anti-evolutionists. However, this argument is flawed and it is crucial to know the reason. For instance, the argument conflates randomness with contingency. This error is rooted in a misreading of the nature of biological contingency as explained by Stephen Jay Gould. He argued that the development of genetic information is not simply random, but dependent on events that have occurred before. He relied on the fact that DNA is a replica of DNA, and they themselves depend on other molecules. In other words, there is a causality that is the basis of every biological process. The argument is also flawed due to its reliance on the laws of physics and the application of science. These statements are not only inherently untrue however, they are also untrue. The science practice presupposes that causal determinism is not strict enough to be able to predict all natural phenomena. In his book, Brendan Sweetman aims to give a balanced, accessible introduction to the relationship between evolutionary theory and Christian theism. He is a patient, rather than a flashy author and this is in keeping with his goals, which include disentangling the scientific value of evolutionary theory from its religious implications, and developing the ability to think clearly about the controversial subject. While the book isn't as thorough as it could be but it does provide a useful overview of the issues involved in this debate. It also makes it clear that evolutionary theory is a well-established scientific theory that is widely accepted by experts in the field, and worthy of a rational acceptance. However the book is less than convincing when it comes to the issue of whether God has any influence on evolution. Trading Pokemon with other trainers is a great method to save Candy and time. Trading Pokemon with other players reduces the cost of evolving certain Pokemon by using the traditional method. This is particularly helpful for high-level Pokemon, which require lots of Candy to evolve.
