The Theory of Evolution The theory of evolution is based on the fact that certain traits are passed down more often than others. These traits allow individuals to survive and reproduce which is why they tend to increase in number over time. Scientists now understand how this process operates. For example an examination of the clawed frog revealed that duplicate genes can result in different functions. Evolution is an inevitable process The natural process resulting in the evolution of organisms best at adapting to their environment is known as “natural selection.” It's one of the primary processes of evolution, alongside mutation, migration, and genetic drift. Those with traits which facilitate reproduction and survival will be more likely to pass the traits to their offspring. This results in gradual changes in gene frequency over time. This results in new species being formed and existing ones being transformed. In the 19th century, Charles Darwin formulated a scientific theory that explained how living organisms changed over time. The theory is based upon the idea that more offspring than could survive are produced, and these offspring compete for resources in their environments. This leads to an “evolutionary struggle” in which those who have the best traits win and others are eliminated. The remaining offspring transmit the genes that confer these desirable traits to their children which in turn gives them an advantage over other members of the same species. As time passes, the number of organisms with these beneficial traits grows. It is difficult to comprehend how natural selection can create new traits if its primary function is to eliminate individuals who are not physically fit. Furthermore, most forms of natural selection deplete genetic variation within populations. Natural selection is not likely to produce new traits without the involvement of other forces. Mutation, drift genetics and migration are three major evolutionary forces that alter gene frequencies. Sexual reproduction and the fact each parent transmits half of their genes to their children speeds up these processes. These genes are called alleles, and they may have different frequencies among individuals of the same species. The frequencies of alleles will determine if a trait is dominant or recessive. A mutation is simply an alteration to the DNA code of an organism. This change causes some cells to grow and develop into a distinct entity, while others don't. Mutations can also increase the frequency of the existing alleles or create new alleles. The new alleles could be passed on to the next generations, and then become the dominant phenotype. Natural selection is the basis of evolution Natural selection is an easy process that alters the populations of living organisms over time. It is a result of the interaction between heritable phenotypic variation and the possibility of differential reproduction. These factors create the situation that people with beneficial characteristics are more likely to survive and reproduce than those with no beneficial traits. As time passes this process can lead to a reshaping of the gene pool, thereby making it more closely aligned with the environment in which individuals reside. This is the principle behind Darwin's “survival of the strongest.” This process is based on the idea that people can adapt to their surroundings by displaying different traits. These traits increase the chance of individuals to survive and reproduce, as well as produce a lot of offspring. In the long term this will allow the trait to spread across a population according to BioMed Central. Eventually all members of the population will be affected and the population will change. This is known as evolution. Those with less-adaptive characteristics will die off or will not be able to produce offspring, and their genes won't be passed on to future generations. In time, genetically modified species will take over the population and evolve into new species. However, this isn't a guarantee. The environment can alter abruptly and make the changes obsolete. Sexual selection is another factor that influences the evolution of. Certain traits are more desirable because they increase the odds of a person mating an individual. This can result in odd phenotypes like brightly colored plumage in birds, or the massive antlers of deer. These phenotypes might not be beneficial to the organism, but they can boost the chances of survival and reproducing. Many students are also confused about natural evolution, as they confuse it with “soft inheritance”. Soft inheritance is not necessary for evolution, but it is usually a key component. This is because it allows for random modification of DNA, as well as the creation of genetic variants which are not immediately useful to an organism. These mutations become the raw material on which natural selection takes action. Genetics is the basis of evolution Evolution is the natural process in which the traits of a species change over time. It is influenced by various factors, such as mutation, gene flow and horizontal gene transfer. The frequency of alleles within a group can also affect the evolution. This permits the selection of traits that are beneficial in new environments. The theory of evolution is a key concept in biology, and has profound implications for understanding of life on Earth. Darwin's theories, along with Linnaeus notions of relatedness and Lamarck theories about inheritance, changed the way traits are passed on from parent to child. Instead of parents passing on their inherited traits through misuse or use, Darwin argued that they were favored or disadvantaged by the environment they lived in and passed this information to their offspring. He called this process natural selection and his book, The Origin of Species explained how this could result in the creation of new species. Genetic changes, also known as mutations, can occur at random in the DNA of a cell. These mutations can trigger many phenotypic traits such as hair color to eye color, and are influenced by a variety of environmental factors. Some phenotypic traits are controlled by multiple genes and some even have more than two alleles, such as blood type (A B or O). Modern Synthesis is a framework that combines Darwinian ideas of evolution and Mendel's genetics. It blends macroevolutionary shifts that are found in fossil records with microevolutionary processes like genetic mutation and trait-selection. Macroevolution is a process that is extremely long and is only visible in the fossil record. In contrast, microevolution is a more rapid process that is visible in living organisms today. Microevolution is driven by genetic selection and mutation, which are smaller scales than macroevolution. It is also accelerated through other mechanisms such as gene flow, or horizontal gene transfer. Evolution is based upon chance Evolutionists have long used the argument that evolution is random. This argument is not true and it is important to know why. The argument confuses randomness with contingency. This is an error that stems from a misreading of the nature of biological contingency, as described by Stephen Jay Gould. He argued that the development of genetic information is not just random, but is 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. read review follows an order of causality. The argument is also flawed because it relies on the principles and practices of science. These statements are not only logically untenable however, they are also untrue. The science of practice supposes that causal determinism not strict enough to accurately predict all natural events. In his book, Brendan Sweetman aims to give a balanced, accessible introduction to the relationship between evolutionary theory and Christian theism. He isn't a flashy author, but a patient one, which fits his objectives that include detaching the scientific status and religious implications of evolutionary theory. The book may not be as thorough as it could have been however, it provides an excellent overview of the debate. It also makes clear that evolutionary theories are well-substantiated, widely accepted and worthy of rational acceptance. The book is not as convincing when it comes down to the question of whether God has any role in evolution. While Pokemon that are traded with other trainers are not able to be cultivated for free, trading them is an excellent method to save Candy and time. The cost of developing certain Pokemon through the traditional method, like Feebas is decreased by trading them with other players. This is particularly beneficial for high-level Pokemon that require a lot of Candy to evolve.
