Editing 15 Best Documentaries About Evolution Site

The Evolution Site<br><br>The theory of evolution by natural selection is the defining force of modern biology. It connects disciplines such as genetics, microbiology and the study of palaeontology.<br><br>However, the study of evolution is often controversial, and the resulting misinformation can confuse people regarding its basic concepts. This site can help explain the most important concepts.<br><br>What is Evolution?<br><br>Modern evolutionary theory focuses on the gradual and cumulative changes that occur in populations over time. These changes are the results of natural selection. This is a process which increases the number organisms with beneficial traits, which allow them to survive and reproduce in certain environments. As a result, these organisms have more offspring than those who don't have these beneficial characteristics. This could result in a genetic mutation that may eventually lead to the creation of new species.<br><br>The term "evolution" is usually associated with "survival-of-the best" which implies that people who are more adaptable to specific environmental conditions will have a distinct advantage over those less well adapted. However this is just one of the many different ways in which evolution can occur.<br><br>Another popular way to use the term "evolution" is to suggest that species are able to move from one stage to the next. This type of view of evolution could be described as anagenetic or cladogenesis. The definition of evolution in science is not in agreement with this view. The theory of evolution that is based on science changes focuses on the changes that occur in populations over time. These changes are caused by mutations which result in natural selection and genetic variation.<br><br>Charles Darwin was one of the scientists who backed this view. Others, such as Alfred Russel Wallace, who developed the theory of macroevolution and believed that this was the only way the higher forms of life could have evolved from the lower ones.<br><br>For a concept to be called a theory, it has to be capable of standing up to rigorous testing and evidence. The evidence for evolution has withstood the test of time and has been backed by numerous studies in many sciences, from geology to biology to astronomy. Evolution is a cornerstone of science and is backed by a majority of scientists around the world. However, many people have misconceptions about the theory of evolution, particularly how it relates to religion.<br><br>What is the Theory of Evolution (Evolutionary Theory)?<br><br>Evolution is the scientific explanation for how living things change over time. It is based on a range of well-established observable facts: that more offspring are often produced than can possibly survive; that individuals differ from each other in their physical characteristics (phenotype) and that various characteristics result in different rates of survival and reproduction and reproduction; and that these traits can be passed down to the next generation. These observations are backed by the increasing body of evidence from molecular biology, palaeontology, climatology, functional morphology and geology.<br><br>Charles Darwin and Alfred Russel Wallace independently developed the theory of evolution through selection in the middle of the 19th century as a way to explain how organisms adapt to their physical and biologic environments. It is the most well-supported and  [https://click4r.com/posts/g/18819677/the-most-powerful-sources-of-inspiration-of-evolution-gaming 에볼루션 바카라 무료] 룰렛 - [http://www.0471tc.com/home.php?mod=space&uid=2408604 Www.0471tc.Com], tested theory in the field of science. Its predictions have been borne out by the fact that, for  [http://bbs.xiaoditech.com/home.php?mod=space&uid=2150898 무료 에볼루션] instance more complex organisms tend to have less genetic mutations than simpler ones. In addition, the more successful an organism is at reproduction and survival, the more likely it will be to pass on its genes to the next generation.<br><br>Some people oppose evolution because they believe that it suggests that there is no purpose for life. However, many scientists who are also religious like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with belief in God but also enhances it (BioLogos 2014).<br><br>In reality, a large number of highly trained evolutionary biologists, some of who are renowned evangelical Christian leaders have been involved in the development and testing of the theory of evolution. Many of these scientists contributed to the understanding a wide range phenomena, including phylogenetics and genomics, as well as the formation and function of fossils.<br><br>The term "theory" is sometimes used in a wrong sense to mean a guess or speculation but in reality it refers to a scientific idea that has been systematically developed and tested over time. Scientists test hypotheses by repeating the experiments or observations that led them to their conclusions. Therefore, the theory of evolution has been repeatedly tested out as have the corresponding theories of Copernican, germ theory, and atomic theory.<br><br>What is the Process of Evolution?<br><br>The process of evolution is the gradual shift over time in the percentage of genetically distinct individuals within a certain species. This change is a result of natural selection, which favors those who are better adapted to their environment. The people who are more adaptable have higher chances of reproduction and survival. As more of these individuals survive and reproduce their genes become more common within the population. This process is sometimes called "survival for the fittest."<br><br>According to theories of evolution, mutations that lead to genomic variation are what triggers evolution. These mutations can occur at random or under the influence of the environment. When mutations occur randomly and the frequencies of alleles will vary from generation to generation. If a mutation is beneficial it can increase the frequency of the allele and cause the allele to spread throughout the population.<br><br>Changes in the frequency of alleles can result in new species over time. The new species will evolve and develop into newer forms. This is a process known as macroevolution. The formation of a new species is often caused by changes in the environment that provide certain types of resources available or cause new environmental problems. For instance, the rise of finches in the Galapagos Islands is a result of the availability of various food sources and the need defend themselves from predators.<br><br>In a broader context it is possible to define evolution as any change in the nature of living organisms over time. This change can be small or even the creation of a new coloration, or massive, for instance, the creation of a new organ.<br><br>Scientists who believe in the theory of evolution generally agree on the significance of genetic change in the process that causes evolution. They also agree that evolution is a process that occurs in time, typically over a period of millions of years. They differ in the importance of various factors that could speed up or slow down this process. For example the role played by sexual selection, environmental pressures, and mutation bias. Despite these differences most scientists believe that evolution is real and that the evidence in support of this is overwhelming.<br><br>What is the Evidence of Evolution?<br><br>Throughout the years since Darwin's time, scientists have gathered evidence to support Darwin's theory of evolution. Some of this evidence comes from fossils, which demonstrate the changing features of living organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography, and genetics are evidence.<br><br>The evolutionary tree is the best method of proving evolution. It shows how different species are related. Another way to prove it is homologous structures, which share a similar structures in different species but serve different purposes, such as the wings of birds and bats. The fact that different species develop and adapt to the same environment is also a sign of evolution. For instance, arctic-foxes and Ptarmigans have white pelts during the winter months that blend into the snow and ice. This is a form of convergent evolutionary process, which suggests that the species share common ancestors.<br><br>Another piece of evidence is the existence of vestigial structures. These are unusable organs which could have served a function in the distant ancestor.

Natural selection causes the structures to shrink when they are no longer used.<br><br>Scientists have also gathered additional evidence for evolution through observation and experimentation. The evidence for evolution is divided into six categories: directly observable small-scale changes, biogeographic patterns as well as comparative anatomy, fossil record, genetics, and classification. Each of these provides compelling evidence that the evolution of life took place.<br><br>Although many people have misconceptions about the theory of evolution it is an empirical fact. It isn't only a theory, it is a potent collection of years of observation and accumulated data that has been proven and tested. Scientists continue to gather and study new information to better understand the arc of the Earth's life, regardless of whether people believe in the theory of evolution or not. This information will help scientists to better understand how to prevent future global catastrophes and how to use the resources of our planet. This will allow us to better serve the needs of people living on this planet.
