The Evolution Site
The concept of natural selection as the basis of evolution is the unifying force in the current biology. It combines disciplines such as microbiology, palaeontology, genetics and palaeontology.
However, the study of evolution is often controversial, and the resultant misinformation can confuse people about its basic concepts. This site clarifies 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 results of natural selection. This is a process which increases the number organisms with beneficial traits, which enable them to thrive and reproduce in particular environments. As a result,

200 noted) these organisms have more offspring than those who don't have these beneficial traits. This results in 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 those people who are most well-adapted to a specific set of environmental conditions will have an advantage over those who are not well-adapted. However this is just one of the many ways that evolution can occur.
Another popular way to use the word evolution is to suggest that species can change from one state to the next. This kind of view can be described as anagenetic, or cladogenesis. The definition of evolution in science does not support this view. The theory of evolution that is based on science change focuses instead on the changes that occur in populations over time. These changes are the result mutations that result from natural selection and genetic variation.
Charles Darwin was one of the scientists who supported this idea. Others, such as Alfred Russel Wallace, who came up with the macroevolution theory and believed that this was the only way the higher forms of life could have evolved from the lower forms.
A theory must stand up to rigorous tests and evidence to be considered a theory. The evidence for evolution has withstood the test of time and has been backed by a myriad of studies across various scientific disciplines, ranging from biology to geology to chemistry to astronomy. In reality, evolution is accepted as one of the foundations of science today and is backed by the majority of scientists across the globe. However, there are many misconceptions about the nature of the theory of evolution,

What is the Theory of Evolution?
Evolution is a scientific explanation of the way living things change over time. It is based on a range of well-established observable facts such as the fact that more offspring are often produced than can possibly survive; that individuals differ from one another in their physical characteristics (phenotype) and that distinct traits confer varying rates of reproduction and survival; and that traits can be passed down to future generations. These observations are supported by a growing amount of evidence derived from molecular biology, palaeontology and climatology functional geology, morphology.
The theory of evolution through natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the late 19th century as an explanation for the reason that organisms are adapted to their physical and biological environments. It is now the best-supported and most extensively tested theory in the field of science. Its predictions have been borne out by the fact that, for example complex organisms are more likely to have fewer genetic mutations than simpler ones. In addition the more successful an organism is at being able to reproduce and survive and reproducing, the more likely it is to pass its genes to future generations.
Some people oppose evolution based on the belief that it implies that there is no purpose to life. Many scientists who are religious like Cambridge Palaeontologist Simon Conway Morris (BioLogos, 2014) believe that evolution is compatible with faith in God and is even enhanced by it.
In fact, a large number of highly qualified evolutionary biologists, including some who are revered evangelical Christian leaders have been involved in the development and testing of the theory of evolution. Many of these researchers 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" which is often used incorrectly refers to scientific hypothesis that has been tested and refined over a long period of time. Scientists test hypotheses by repeating the experiments or observations that led them to their conclusions. Thus the theory of evolutionary theory has been repeatedly proven,

What is the Process of Evolution?
The process of evolution is a gradual change in the genetically diverse individuals within a species over time. This is the result of natural selection, which favors those who are better adapted for their environment. The individuals who are more adapted have higher chances of reproducing and survival. As more individuals survive and reproduce, their genes are more common within the population. This is often described as "survival of the fittest."
According to the theory of evolution the mutations that cause genetic variation are the primary reason for evolution. These mutations could occur randomly or be influenced by the environment. If mutations are random, the frequencies of the resulting alleles may vary from generation to generation. If a mutation is beneficial it can increase the frequency of the allele, causing the allele to be spread across the population.
Changes in the frequency of alleles can result in new species as time passes. The new species will develop and evolve into new forms. This is a process called macroevolution. The development of new species is often caused by changes in the environment, which makes certain resources available or creates new environmental problems. The development of finches in the Galapagos Islands, for example is due to the availability of fresh food and the necessity to defend themselves from predators.
In a broader context the term "evolution" can be described as any change in the character of living organisms over time. The change could be small or even the creation of a new coloration, or even massive, like the formation of a new organ.
Scientists who accept the theory of evolution generally recognize the importance of genetic changes in the process of generating evolution. They also acknowledge 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 instance the role of sexual selection, environmental pressures, and mutation bias. Despite these differences, the majority of scientists still believe that evolution is real and

What is the Evidence of Evolution?
Since Darwin's time, scientists have collected evidence that supports his theory of evolution. A portion of this evidence is derived from fossils which demonstrate the changing features 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 method of proving evolution. It demonstrates how species are related. Homologous structures are another evidence.
