The Evolution Site The concept of natural selection as the foundation of evolution is the defining factor in modern biology It ties together disciplines as diverse as genetics microbiology and Palaeontology However the study of evolution is often controversial and the resultant misinformation can confuse people about the fundamentals of evolution This Web site helps clarify essential concepts What is Evolution The modern understanding of evolution is based on the gradual and cumulative changes that happen within populations over time These changes are the result of natural selection This is a process which increases the number organisms with beneficial traits which enable them to thrive and reproduce in specific environments In turn these organisms leave more offspring than those that dont possess the beneficial characteristics This causes a genetic change that can eventually lead to the creation of new species The term evolution is often associated with survivalofthe best which implies that individuals who are better adapted to certain environmental conditions will have a distinct advantage over those less well adapted In reality this is only one of many ways that evolution could occur Another popular way in which the word evolution is used is to suggest that a species will eventually change from one state to the next state of being This type of view of evolution could be referred to as anagenetic or cladogenesis This view is not supported by the definition of evolution that is scientifically accepted The evolutionary theory that scientists have developed change is based on changes that occur in populations over time These changes are the result of mutations that result from natural selection and genomic variation Charles Darwin was one of the scientists who backed this view Others including Alfred Russel Wallace who came up with the macroevolution theory and believed that this was the only way the higher forms of life could be derived from lower ones 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 countless scientific disciplines from geology to biology chemistry to astronomy In fact evolution is considered to be one of the foundations of science today and is backed by the majority of scientists across the globe Many people have misconceptions regarding the nature of the evolution theory especially how it relates to religion What is the Theory of Evolution Evolution is a scientific explanation of the way living things change over time It is based on few known facts that more offspring are produced than can be surviving as individuals differ in their physical characteristics and that they are able to pass on traits to the next generation These observations are supported by the increasing body of evidence from molecular biology palaeontology climatology functional morphology and geology The theory of evolution based on natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the mid19th century to explain the reason that organisms are adapted to their biological and physical environment It is the most widely supported and validated theory in science Its predictions were confirmed by the fact for example that more complex organisms have less genetic mutations Additionally the more efficient an organism is in being able to reproduce and survive and reproducing the more likely it will be to pass on its genes to the next generation Some people are against evolution because they think it suggests that there is no purpose to life Many scientists who are religious believers like Cambridge palaeontologist Simon Conway Morris BioLogos 2014 believe that evolution is compatible with faith in God and is even enhanced by it In actual fact a significant number of highly skilled evolutionary biologists including a few who are renowned evangelical Christian leaders are involved in the creation and testing of the theory of evolution Many of these scientists contributed to the understanding a broad range of phenomena including genomics and phylogenetics as well as the formation and function of fossils The term theory which is often misused refers to a scientific hypothesis that has been tested and refined over a period of time Scientists test hypotheses by repeating the experiments or observations that led them to their conclusions Thus the theory of evolution has been repeatedly tested out as have the corresponding theories of Copernican germ theory and atomic theory What is the Process of Evolution The process of evolution is the gradual shift over time in the ratio of genetically distinct individuals within a specific species This change is the result of natural selection of individuals who are more adapted to their environment The more adapted individuals have a greater chance of survival and reproduction As more of these individuals survive and reproduce their genes are more prevalent within the population This process is sometimes described as survival of the strongest According to the theory of evolution mutations that lead to genomic variation are what drives evolutionary change These mutations can occur at random or under the influence of the environment When mutations are random the frequency of the resultant alleles could 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 The changes in frequency of alleles could lead to new species as time passes The new species will evolve and develop into newer forms This process is known as macroevolution The development of an entirely new species is typically caused by changes in the environment that provide certain types of resources available or cause new environmental challenges For instance the rise of finches on the Galapagos Islands is a result of the availability of different food sources and the need protect themselves from predators In a larger sense the term evolution can be described as any change in the character of living organisms over time The change could be subtle such as the development of new coloration or dramatic like the formation of an organ Scientists who believe in the theory of evolution generally agree on the significance of genetic changes in the process of generating evolution They also agree that the process of evolution occurs over a lengthy period of time often millions of years They differ on the importance of different factors that may speed up or slow down the process For instance the role of sexual selection environmental pressures and mutation bias Despite these disagreements most scientists believe that evolution is real and that the evidence in support of this is overwhelming What evidence do we have to support evolution In 에볼루션 카지노 since Darwins time scientists have gathered evidence to support Darwins theory of evolution Some of this evidence comes from fossils which reveal the changing traits of living organisms over time Similarities between living and nonliving organisms as well as embryology biogeography and genetics are further evidence The main proof of evolution is in the evolutionary tree which illustrates how different species are connected Another evidence source is homologous structures which have similar structures in different species but perform distinct functions like the wings of birds and bats Evolution is evident in that different species adapt and develop to similar environments For instance arcticfoxes and Ptarmigans sport white pelts during the winter months that blend in with the snow and ice This is a type of convergent evolutionary mechanism which suggests the species shared ancestors Vestigial structures are a different piece of evidence These are parts of an organism which may have served a purpose in the distant past For example the human appendix may be an oblique reminder of an organ that was used to digest food These structures tend to shrink in size once they are no longer utilized in a process called natural selection Scientists have also gathered other evidence for evolution through observation and experimentation The evidence for evolution can be grouped into six distinct categories directly observed changes at a smaller scale biogeographic distributions comparative anatomy fossil records genetics Each of these provides compelling evidence that evolution of life has occurred Although many people have misconceptions about the theory of evolution It is a scientific fact It isnt simply a flimsy theory It is a potent collection of decades of observations and data that has been tested and proven No matter what people believe or deny about the theory of evolution scientists continue to research and discover new information in order to further comprehend the evolution of life on Earth This information will help scientists to better understand how we can avoid future global catastrophes and how best to make use of the resources on our planet This information will also allow us to better serve the needs and desires of the people living on our planet
