The Evolution Site
The theory of evolution through natural selection is the defining force of modern biology. It ties together disciplines such as genetics, microbiology, and the study of palaeontology.
However the study of evolutionary theory is often controversial, and the misinformation that results can confuse people about the fundamentals of evolution. This website helps to explain the most important concepts.

What is Evolution?
Modern evolutionary theory is based on the gradual and cumulative changes that take place in populations over time. These changes are the result of natural selection, which increases the number of organisms who possess beneficial traits that allow them to survive and reproduce in a specific environment.
에볼루션사이트 produce more offspring because of their positive characteristics. This can lead to a genetic mutation which could eventually lead to the creation of new species.
The term "evolution" is often ascribed to the notion of "survival of the strongest," which implies that those individuals who are best adapted to a particular set of environmental conditions will have an advantage over those who aren't well-adapted. In reality it is only one of the many different ways that evolution could occur.
Another popular way to use the word evolution is to suggest that species are able to move from one stage to the next. This view of evolution is called anagenetic or cladogenesis. This is not backed by the definition of evolution that is scientifically accepted. The scientific theory of evolutionary change is based on changes that occur in populations over time. These changes are the result of mutations that produce natural selection and genomic variation.
Charles Darwin was one of the scientists who supported this view. Others, such as Alfred Russel Wallace, who developed the theory of macroevolution believed that this was the only way the higher forms of life could be derived from lower forms.
In order for a concept to be called a theory, it must be capable of surviving rigorous tests and evidence. The evidence for evolution has stood up to the test of time and has been supported by numerous studies in various scientific disciplines, ranging from biology to geology to chemistry to astronomy. Evolution is a cornerstone of science and is supported by the majority of scientists across the world. Many people are misinformed about the nature of the evolution theory, especially how it relates with religion.
What is the Theory of Evolution (Evolutionary Theory)?
Evolution is the scientific explanation of the way living things change over time. It relies on a number of well-established observable facts such as the fact that more offspring are created than are likely to survive; that individuals differ from one another in their physical characteristics (phenotype); that different traits confer varying rates of survival and reproduction; and that traits can be passed down to the next generation. These observations are supported by an increasing body of evidence drawn from molecular biology, palaeontology climatology functional geology, morphology.
Charles Darwin and Alfred Russel Wallace independently developed the theory of evolution based on selection in the mid-19th Century as a reason why organisms are able to adapt to their physical and biologic environments. It is now the best-supported and widely-tested theory in the field of science. Its predictions were proven by the evidence, for example that more complex organisms have fewer genetic mutations. Additionally the more successful an organism is at reproduction and survival and reproducing, the more likely it is to pass on its genes to future generations.
Some people are against evolution because they think it implies there is no reason for existence. 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 can even be enhanced by it.
In fact, a large number of highly skilled evolutionary biologists, including a few who are revered evangelical Christian leaders have been involved in the creation and testing of the theory of evolution. Many of these scientists contributed to the understanding of a wide range phenomena, including phylogenetics and genomics, as well as the formation and function of fossils.
The word "theory" is often used in a wrong sense to mean a speculation or guess but in reality it refers to a scientific idea that has been systematically evaluated and refined over time. Scientists test their theories by repeating the experiments or observations that have led to them. So the theory of evolutionary theory has been repeatedly confirmed as have the corresponding theories of Copernican theory, atomic theory, and germ theory.
What is the Process of Evolution?
The process of evolution is a gradual shift in the genetic makeup of different individuals within a species over time. This change is a result of natural selection, which favors individuals who are better adapted for their environment. The more adapted individuals have a better chance of survival and reproduction. As more of these individuals survive and reproduce their genes become more common in the general population. This process is sometimes called "survival of the most fittest."
According to the theory of evolution, the mutations that produce genomic variation are the raw basis for evolutionary change. These mutations could occur at random or be influenced by the environment. When mutations occur randomly and the frequencies of alleles can vary from generation-to-generation. When a mutation is beneficial it can increase the frequency of the allele which causes the allele to spread throughout the population.
The changes in frequency of alleles can lead to new species in the course of time. The new species can then grow and evolve into newer forms. This is known as macroevolution. The development of an entirely new species is typically caused by changes in the environment that allow certain kinds of resources to become available or create new environmental challenges. For example, the evolution of finches in the Galapagos Islands is a result of the abundance of food sources and the need to protect themselves from predators.
In a broader context it is possible to define evolution as any change in the characteristics of living organisms over time. The change could be subtle, such as the development of new colors or a dramatic change, such as the development of an organ.
Scientists who believe in evolution theory generally agree that genetic changes are crucial in the process of the process of generating evolution. They also acknowledge that the process of evolution takes place over a long time, usually millions of years. However, they differ on the importance of different factors that speed up or slow down this process, such as the role of environmental pressures, sexual selection and mutation bias. Despite these differences, the majority of scientists believe that evolution has happened and that the evidence for this is overwhelming.
What is the evidence for evolution?
Throughout the years since Darwin's time, scientists have gathered evidence that supports his theory of evolution. A portion of this evidence is derived from fossils which show the changing characteristics of living things over time. Other evidence is found in similarities between living organisms embryology, biogeography genetics and comparative anatomy.
The evolutionary tree is the best way to prove evolution. It shows how species are related. Another source of evidence is homologous structures, which share a similar structure in different species but have distinct functions such as the wings of bats and birds. The fact that different species develop and adapt to the same environment is also a sign of evolution. For example, arctic-foxes and Ptarmigans wear white fur coats which blend with snow and ice. This is a type of convergent evolution, which suggests that the species has common ancestral ancestors.
The vestiges of structures are another source of evidence. These are parts of an organism that may have served some purpose in the past. The human appendix, for instance is a remnant of an organ that was used to digest food. Natural selection causes the structures to shrink when they are no longer used.
Scientists have also collected evidence for evolution through observation and testing. The evidence for evolution can be divided into six categories: directly visible small-scale changes in biogeographic distribution and comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that the evolution of life took place.
Many people have misconceptions regarding the theory of evolution. But, it's an actual fact. It isn't only a theory, it is a powerful collection of years of observations and data that has been proven and tested. No matter what people believe or deny about the theory of evolution, scientists continue to study and collect new data in order to further comprehend the evolution of life on Earth. This knowledge will allow scientists to better understand how to prevent future global catastrophes and how best to make use of the resources on our planet. This will allow us to better meet the needs of all the people on this planet.
