The Evolution Site The theory of natural selection as the foundation of evolution is the defining factor in the field of modern biology. It ties together disciplines that are as diverse as genetics microbiology, and Palaeontology. The study of evolution can be controversial and the misinformation that comes from it can lead to confusion over its fundamentals. This site can help clarify essential concepts. What is Evolution? Modern evolutionary theory is based on the gradual and cumulative changes that occur in populations over time. These changes are the result of natural selection, which increases the number of organisms who possess beneficial traits that enable them to live and reproduce in a particular environment. They produce more offspring because of the positive characteristics. This can result in a genetic mutation which could eventually result in new species. The term “evolution” is often associated with the notion of “survival of the strongest,” which implies that people who are most well-adapted to a particular environment will have an advantage over those who are not well-adapted. This is just one of many ways that evolution can occur. Another way of using the term “evolution” is to suggest that species can change from one state to the next. This kind of view can be described as anagenetic, or cladogenesis. This view is not supported by the definition of evolution in science. Instead the scientific theory of evolution is based on the changes that take place in populations over time and these changes are the result of genetic mutations and natural selection. Charles Darwin was one of the scientists who backed this view. Alfred Russel Wallace who developed the macroevolution theory believed that this was only way the higher living forms could have evolved. For a concept to be considered a theory, it must be capable of surviving rigorous testing and evidence. Evolution has stood the test of time and has been proven to be valid in many scientific disciplines, from biology to geology, from astronomy to chemistry. Evolution is the foundation of science and is believed by the majority of scientists around the globe. Many people are misinformed about the nature of the theory of evolution, especially how it relates to religion. What is the Theory of Evolution (Evolutionary Theory)? Evolution is the scientific explanation for the way living things change over time. It is based on a few well-established facts: that many more offspring are created than can survive, that individuals differ in their physical characteristics, and that they can pass on traits to future generations. These observations are supported by an increasing body of evidence drawn from molecular biology, palaeontology and climatology functional geology and morphology. The theory of evolution by natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the late 19th century to provide an explanation for how organisms adapt to their physical and biological environments. It is now the best-supported and most widely tested theory in the field of science. Its theories have been proven out by the fact that, for instance more complex organisms tend to have fewer genetic mutations than simpler ones. The more successful an organism is in terms of survival and reproducing the more likely it is to pass its genes on to future generations. Some people oppose evolution based on the belief that it implies that there is no purpose to life. Many scientists who are religious such as the Cambridge Palaeontologist Simon Conway Morris (BioLogos, 2014), believe that evolution is compatible with faith in God and is even enhanced by it. In fact, a large number of highly trained evolutionary biologists, some of who are renowned evangelical Christian leaders are involved in the development and testing of the theory of evolution. Many of these scientists have contributed to the understanding of a wide variety of phenomena like phylogenetics, genomics, and the formation and role of fossils. The term “theory” is sometimes used incorrectly to mean a speculation or guess but in reality it refers to a scientific hypothesis that has been systematically developed and tested over time. Scientists test hypotheses through repeating the experiments or observations that led them to the conclusion. So the theory of evolution theory has been repeatedly confirmed along with the related theories of Copernican theory as well as atomic theory and germ theory. What is the Process of Evolution? The process of evolution is a gradual shift in the proportions of genetically diverse individuals within a species over time. This change is a result of natural selection, which favors those who are better adapted for their environment. The more adapted individuals have better chances of reproduction and survival. As more of these individuals survive and reproduce their genes, they become more common within the population. This is sometimes referred to as “survival for the strongest.” According to theories of evolution, mutations that lead to genomic variation are what drives evolutionary change. These mutations can occur randomly or under the influence of the environment. When mutations are random, the frequency of the resultant alleles could vary from generation to generation. In contrast, when an alteration is beneficial, it increases the frequency of the allele, causing it to spread throughout the population. Changes in the frequency of alleles can lead to new species over time. The new species could develop further and evolve into newer forms. This is known as macroevolution. The formation of a new species is often caused by changes in the environment which allow certain kinds of resources to become available or cause new environmental challenges. For example, the evolution of finches in the Galapagos Islands is a result of the abundance of foods and the need to defend themselves from predators. In a broader sense it is any change that occurs in the characteristics of organisms over time. This change can be subtle, like the development of new coloration or dramatic, like the development of an organ. Scientists who believe in the theory of evolution generally agree that genetic changes are important in the process of generating evolution. They also acknowledge that the process of evolution occurs over a long time, often millions of years. However, they differ on the importance of different factors in speeding or slowing the process, like the impact of environmental pressures, sexual selection and mutation bias. Despite these differences, most scientists believe that evolution is happening and that evidence for this is overwhelming. What evidence do we have to support evolution? Since Darwin's time, scientists have collected evidence to support his theory of evolution. The evidence comes from fossils that show the evolution of living organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography and genetics are further evidence. The primary evidence of evolution is in the evolutionary tree, which demonstrates how different species are connected. Homologous structures are another evidence. They share a common structure but serve different purposes in different species, such as the wings of a bird or bat. Evolution is evident in that various species adapt and evolve to similar environments. For instance, arctic-foxes and Ptarmigans wear white seasonal pelts that blend in with the snow and ice. This is a form of convergent evolutionary, which suggests that the species have common ancestors. Vestigial structures are a different piece of evidence. They are the remains of an organism that may have served a purpose in the distant past. For 에볼루션 블랙잭 may be remnants of an earlier organ used to digest food. These structures tend to shrink in size once they're no longer in use which is a process referred to as natural selection. Scientists have also gathered other evidence for evolution through observation and experimentation. The evidence for evolution can be divided into six distinct categories: directly observable changes at a small scale biogeographic distributions, comparative anatomies, the fossil record and genetics. Each of these provides convincing evidence that the evolution of life took place. While many people are misinformed about the theory of evolution, it is a scientific fact. It is not a theory, but a powerful collection of evidence built on years of observation. Scientists continue to gather and analyze new data to better understand the arc of Earth's existence, regardless of whether people believe in the theory of evolution or not. This information will help scientists understand how to prevent future global catastrophes and how to make the most of our planet's resources. This will allow us to better serve the needs of people living on this planet.
