The Evolution Site

The concept of natural selection as the foundation of evolution is the defining factor in the field of modern biology. It connects disciplines like microbiology, palaeontology, and genetics.

However the study of evolution is often controversial and the resulting misinformation can confuse people about its basic concepts. This Web site helps explain the most important concepts.

What is Evolution?

Modern evolutionary theory focuses on the gradual and cumulative changes that occur in populations over time. These changes are a result of natural selection, a process that increases the number of organisms who have beneficial traits that allow them to survive and reproduce in a particular environment. This means that these organisms leave more offspring than those who don't possess the beneficial characteristics. This can cause a genetic change that may eventually result in new species.

The term "evolution" is often ascribed to the notion of "survival of the strongest," which implies that individuals who are best adapted to a particular set of environmental conditions will be more successful than those who are not well-adapted. However this is just one of the many ways in which evolution can occur.

Another way that the term "evolution" is used to suggest that a species will invariably change from one state of being to the next one. This kind of view can be referred to as anagenetic, or cladogenesis. This view is not supported by the definition of evolution that is scientifically accepted. The scientific theory of evolutionary 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 backed this view. Alfred Russel Wallace who developed the macroevolution theory believed that this was only way the higher forms of living could have evolved.

A concept must be able stand against rigorous tests and evidence in order to be considered a theory. Evolution has stood the test of time, and has been backed by countless scientific disciplines from geology to biology from astronomy to chemistry. Evolution is a fundamental concept in science and is supported by the majority of scientists around the globe. Many people are misinformed about the nature of the evolution theory particularly how it is connected with religion.

What is the Theory of Evolution?

Evolution is an explanation for the way living things change over time. It is based upon a few well-established facts: that many more offspring are produced than can survive as individuals differ in their physical traits and they are able to pass on traits to the next generation. These observations are backed by the growing body of evidence from molecular biology, palaeontology functional morphology, climatology and geology.

The theory of evolution by natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the mid-19th century to provide an explanation for why organisms are adapted to their biological and physical environments. It is the most widely supported and tested theory in the field of science. Its predictions were proven by the evidence, for example that more complex organisms have less genetic mutations. The more successful an organism is in terms of survival and reproducing, the more likely it will transmit its genes to the next generation.

Some people are against evolution because they believe that it implies that there is no purpose to life. However, many scientists who are also religious like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with faith in God but can be enhanced by it (BioLogos 2014).

Many highly skilled evolutionary biologists have been involved in developing and testing the theory of evolution, which includes several revered evangelical Christian leaders. Many of these scientists have contributed to the understanding of a wide range of phenomena, such as phylogenetics, genomics and the formation and function of fossils.

The word "theory", which is often misused is a reference to a scientific hypotheses that have been tested and refined over time. Scientists test hypotheses by repeating the experiments or observations that led them to the conclusion. Thus, the theory of evolution has been repeatedly borne out as have the corresponding theories of Copernican, atomic and germ theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the genetically different individuals within a particular 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 higher chances of reproduction and survival. As  에볼루션 코리아  survive and reproduce their genes become more prevalent in the general population. This is sometimes described as "survival of the fittest."

According to the theory of evolution the mutations that cause genomic variation are the primary basis for evolutionary change. These mutations may occur randomly or under the influence of the environment. When mutations occur randomly and occur in a random manner, the frequency of the allele may vary from generation to generation. When the mutation is beneficial it increases the frequency of the allele, which causes it to spread throughout the population.

As time passes, these changes in allele frequencies can lead to the formation of new species. The new species may grow and evolve into newer forms. This is known as macroevolution. The development of a new species is often due to changes in the environment which provide certain types of resources available or create new environmental challenges. The evolution of finches in Galapagos Islands, for example, is due to the availability of fresh food and the necessity to defend 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, like the development of new coloration or a dramatic change, such as the development of an organ.

Scientists who accept evolution theory generally agree that genetic change is crucial in the process of creating evolution. They also believe that evolution is a process that takes place in time, typically over millions of years. They differ on the importance of various factors that can accelerate or slow down the process. For example the role of sexual selection, environmental pressures, and mutation bias. Despite these differences, the majority of scientists still believe that evolution is real and that the evidence to support this is overwhelming.

What is the evidence for evolution?

Since Darwin's time scientists have collected evidence to support his theory of evolution. This evidence comes from fossils that demonstrate the evolution of living organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography and genetics are also evidence.

The most important proof of evolution can be found in the evolutionary tree, which illustrates how different species are related. Homologous structures are another evidence. They have a similar structure but serve different purposes in different species, such as the wing of a bat or bird. The fact that different species develop and adapt to the same environment is also a sign of evolution. For instance, arctic foxes and ptarmigans develop seasonal white pelts that blend in with snow and ice. This is a form of convergent evolutionary mechanism, which suggests that the species have shared ancestral ancestors.

Vestigial structures are a different piece of evidence. They are the remains of an organism that may serve a function in the distant past. For example, the human appendix is a vestige of a once-used organ that served to digest food. These structures tend to shrink in size as they are no longer utilized which is a process referred to as natural selection.

Scientists have also gathered additional evidence of evolution through observation and experimentation. The evidence for evolution is divided into six categories: directly observed small-scale changes, biogeographic distribution and comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that the evolution of life has taken place.

Many people have misconceptions regarding the theory of evolution. However, it is an actual fact. It isn't simply a flimsy theory. It is a potent collection of years of observation and accumulated data that has been tested and proven. Scientists continue to collect and analyze new data to better understand the history of Earth's evolution regardless of whether people believe in the theory of evolution or not. This information will aid scientists understand how to prevent future catastrophes on the planet and how to make the most of our planet's resources. It will also enable us to better serve the needs of people living on this planet.
