The Evolution Site
The theory of evolution based on natural selection is the defining force of modern biology. It connects disciplines such as genetics, microbiology and Palaeontology.
However the study of evolutionary theory is often controversial and the resulting misinformation can confuse people about its basic concepts. This site can help to clarify the fundamental concepts.
What is Evolution?
Modern evolutionary theory is based on the gradual and cumulative changes that occur in populations over time. These changes are caused by natural selection, a process that increases the amount of organisms that have traits that are beneficial and allow them to survive and reproduce in a specific environment. This means that these organisms have more offspring than those that do not have the beneficial characteristics. This leads to an alteration in genetics that could eventually lead to the creation of new species.
The term "evolution" is often associated with the notion of "survival of the fittest," which implies that individuals who are best adapted to a specific set of environmental conditions will have an advantage over those who are not well-adapted. This is just one of many ways in which evolution can happen.
Another popular way to use the word evolution is to suggest that a species can change from one state to the next. This kind of view can be referred to as anagenetic or cladogenesis. The definition of evolution in science does not support 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 the result mutations which result in natural selection and genetic variation.
Charles Darwin was one of the scientists who supported this theory. Others, such as Alfred Russel Wallace, who created the macroevolution theory, believed that this was the only way the higher forms of life could be derived from lower forms.
To be able to be called a theory, it has to be capable of surviving rigorous tests and evidence. Evolution has stood the test of time, and
에볼루션게이밍 has been backed by many scientific disciplines, from geology to biology the sciences of astronomy to chemistry. In fact, evolution is accepted as one of the fundamental tenets of science today, and it is supported by the majority of scientists around the world. However, many people have misconceptions about the nature of the theory of evolution, particularly how it relates to religion.
What is the Theory of Evolution (Evolutionary Theory)?
Evolution is an explanation in science 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 often produced than could possibly survive and that individuals differ from one another 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 on to the next generation. These findings are supported by the growing body of evidence from molecular biology, palaeontology, functional morphology, climatology and geology.
The theory of evolution based on natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain how organisms adapt to their biological and physical environment. It is the most widely accepted and tested theory in the field of science. Its predictions have been borne out by the evidence that, for instance more complex organisms have fewer genetic mutations than simpler ones. The more successful an organism is in terms of survival and reproducing the more likely it will transfer its genes to the next generation.
Some people object to evolution based on the belief that it implies that there is no reason to life. However, many scientists who are also religious believers like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with faith in God but is enhanced by it (BioLogos 2014).
Many highly qualified evolutionary biologists have been involved in developing and testing the theory of evolution, including several revered evangelical Christian leaders. Many of them have contributed to the understanding of a vast variety of phenomena including phylogenetics and genomics and the formation and function of fossils.
The term "theory" which is often misused refers to scientific hypothesis that has been tested and refined over a long period of time. Scientists test hypotheses through repeating the experiments or observations that led them to their conclusions. Thus, the theory of evolutionary theory has been repeatedly proven, along with the related 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 genetically diverse individuals within a species over time. This change is a result of natural selection, which favors those who are better adapted to their environment. The more adapted individuals have a better chance of survival and reproduction. As more of these people survive and reproduce, their genes become more common in the general population. This process is sometimes described as "survival of the most fittest."
According to theories of evolution the mutations that cause genetic variation are the primary reason for evolutionary change. These mutations may 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. When a mutation is beneficial it will increase the allele frequency, causing the allele to spread throughout the population.
The changes in frequency of alleles can lead to new species as time passes. The new species may grow and evolve into newer forms. This is known as macroevolution. The creation of a new species is often due to changes in the environment which make certain kinds of resources available or cause new environmental problems.

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 minor, such as the development of a new coloration,

Scientists who believe in evolution theory generally believe that genetic change is essential in creating evolution. They also agree that evolution is a process that takes place over time, usually over a period of millions of years. However, they differ over the role of different factors that speed up or slow down the process, including the role of environmental pressures, sexual selection, and mutation bias. Despite these differences, most scientists believe that evolution has occurred and that evidence for this is overwhelming.
What is the Evidence of Evolution?
Since Darwin's time scientists have collected evidence to support his theory of evolution. A portion of this evidence comes from fossils, which demonstrate the changing features of organisms through time. Similarities between living organisms as well as embryology, biogeography and genetics are also evidence.
The evolutionary tree is the best method to prove the existence of evolution. It demonstrates how species are related. Homologous structures are another proof. They have a similar structure but serve different purposes in different species, like the wings of a bird or bat. Evolution is also evident in the fact that different species adapt and develop to similar environments.
