The Evolution Site
The theory of natural selection as the foundation of evolution is the central force in the current biology. It combines disciplines like genetics, palaeontology and microbiology.
The study of evolution can be controversial and the misinformation that is generated can lead to confusion over its basic concepts. This website helps to to clarify the fundamental concepts.
What is Evolution?
Modern evolutionary theory is based on the gradual and cumulative changes that happen in populations over time. These changes are caused by natural selection, a process that increases the number of organisms who possess beneficial traits that help them survive and reproduce in a specific environment. As a result, these organisms have more offspring than those that don't possess the beneficial traits. This leads to the genetic changes that can eventually lead to the development of new species.
The term "evolution" is frequently associated with the idea of "survival of the fittest," which implies that people who are the most adapted to a specific set of environmental conditions will be more successful than those who aren't adapted to the environment. This is only one of the many ways that evolution could occur.
Another popular way to use the word evolution is to suggest that species can change from one state to the next. This theory of evolution is called anagenetic or cladogenesis. This theory is not supported by the definition of evolution in science. The evolutionary theory that scientists have developed changes focuses on the changes that occur in populations over time. These changes are caused by mutations that produce natural selection and genetic variation.
Some scientists, including the great Charles Darwin, advocated this theory of evolution. Others,

A concept must be able stand

The evidence of evolution has stood up to the test of time and has been backed by numerous studies in a wide range of scientific disciplines, from biology to geology, chemistry to astronomy. In actual fact evolution is considered to be one of the cornerstones of science today, and it is supported by the vast majority of scientists around the world. Many people are confused about the nature of the evolution theory, especially how it relates to religion.
What is the Theory of Evolution (Evolutionary Theory)?
Evolution is the scientific explanation of the way living things change over time. It is based on a range of well-established observations that show that more offspring are often produced than could possibly survive and that individuals differ from one another in their physical characteristics (phenotype); that different traits have different rates of survival and reproduction; and that traits can be passed down to the next generation. These observations are supported by the growing body of evidence from molecular biology, palaeontology functional morphology, climatology, and geology.
The theory of evolution by natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to provide an explanation for the reason that organisms are adapted to their biological and physical environment. It is currently the most well-supported and widely-tested theory in all of science. Its predictions have been borne out by the fact that, for instance complex organisms tend to have fewer genetic mutations than simpler ones. Additionally the more successful an organism is in reproduction and survival, the more likely it will be to pass its genes to the next generation.
Some people are against evolution based on the belief that it implies that there is no purpose to life. Many scientists who are religious believers, like the Cambridge Palaeontologist Simon Conway Morris (BioLogos, 2014) believe that evolution is compatible with faith in God and is even enhanced by it.
In reality, a large number of highly qualified evolutionary biologists, including some who are revered evangelical Christian leaders have been involved in the creation and

The word "theory" is often used in a wrong sense to mean a guess or speculation however it actually refers to a scientific hypothesis that has been systematically tested and refined over time. Scientists test hypotheses through repeating the experiments or observations that led them to their conclusions. So the theory of evolution theory has been repeatedly proven, as well as the related theories of Copernican theory,

What is the Process of Evolution?
The process of evolution is the gradual change over time in the proportion of genetically distinct individuals within a particular species. This is the result of natural selection of those who are more well-adapted to their environment. The more adapted individuals have better chances of reproduction and survival. As more of these individuals survive and reproduce, their genes are more prevalent in the population. This process is sometimes called "survival of the most fittest."
According to theories of evolution the mutations that cause genomic variation are what drives evolutionary change. These mutations can occur randomly or be influenced by the environment. When mutations are random the resulting allele frequencies may differ from generation to generation. When a mutation is beneficial, it will increase the frequency of the allele, which causes it to spread across the population.
As time passes, these changes in allele frequencies can lead to the formation of new species. The new species could develop further and evolve into newer forms. This is a process known as macroevolution. The formation of a new species is usually due to changes in the environment which provide certain types of resources available or create new environmental problems. The development of finches in the Galapagos Islands, for example, is due to the availability of new foods and the necessity to defend themselves against predators.
In a larger sense it is possible to define evolution 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 accept evolution theory generally agree that genetic change is essential in creating evolution. They also acknowledge that the process of evolution takes place over a lengthy period of time, typically millions of years. They differ on the importance of various factors that may speed up or slow down this process. For instance the role of sexual selection, environmental pressures and
에볼루션 게이밍 mutation bias. Despite these differences, the majority of scientists believe that evolution has occurred and the evidence to prove this is overwhelming.
What evidence do we have to support evolution?
Since Darwin's time, scientists have gathered evidence to support his theory of evolution. Some of this evidence is derived from fossils which show the changing characteristics of living organisms over time. Another evidence comes from similarities among living organisms embryology, biogeography genetics and comparative anatomy.
The evolutionary tree is the best method to prove the existence of evolution.
