The Evolution Site

The theory of natural selection as the underlying principle of evolution is the central force in the current biology. It connects disciplines such as microbiology, palaeontology, genetics and palaeontology.

The study of evolution can be controversial, and the misinformation that is generated can lead to confusion about the fundamentals of evolution. This Web site helps explain the most important concepts.

What is Evolution?

The modern conception of evolution focuses 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 of organisms that have beneficial traits, which allow them to thrive and reproduce in certain environments. They produce more offspring as a result of the positive traits. This causes the genetic changes that can eventually lead to the creation of new species.

The term "evolution" is often associated with "survival-of-the most fittest" which implies that individuals who are more adaptable to specific environmental conditions will have an advantage over those who are less well-adapted. However, this is only one of the many ways that evolution can occur.

Another way of using the word evolution is to suggest that species are able to move from one stage to the next. This type of view of evolution could be referred to as anagenetic or cladogenesis. This view is not supported by the scientific definition of evolution. Instead, the scientific theory of evolution concentrates on the changes that happen within populations over time and these changes are caused by genetic mutations and natural selection.

Some scientists, 에볼루션 including the great Charles Darwin, advocated this view of evolution. Alfred Russel Wallace who developed the macroevolution theory believed that this was the only way that higher forms of living could have evolved.

A concept must be able stand 에볼루션게이밍 against rigorous tests and 에볼루션 룰렛 evidence to be considered as a theory. Evolution has stood the test of time, and has been proven to be valid in countless scientific disciplines from geology to biology, from astronomy to chemistry. In reality evolution is regarded as one of the fundamental tenets of science today, and is supported by the vast majority of scientists around the world. Many people are misinformed about the nature of the evolution theory and how it connects with 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 few well-established facts: that many more offspring are born than can survive and that different individuals have their physical traits and they can pass on traits to the next generation. These observations are supported by a growing body of evidence derived from molecular biology, palaeontology and climatology functional geology and morphology.

The theory of evolution by natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain why organisms are adapted to their biological and physical environments. It is the most widely supported and tested theory in science. Its predictions were proved by the fact, for example that more complex organisms are less susceptible to genetic mutations. Additionally, the more efficient an organism is in being able to reproduce and survive in its ability to reproduce, the more likely it is to pass its genes to future generations.

Some people oppose evolution because they believe that it implies that there is no meaning 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 fact, a large number of highly trained evolutionary biologists, some of who are respected evangelical Christian leaders are involved in the development and 에볼루션 코리아 testing of the theory of evolution. Many of them have contributed to the understanding of a wide variety of phenomena such as phylogenetics, genomics and the formation and role of fossils.

The word "theory" is often used in a wrong sense to mean a guess or speculation however it actually refers to a scientific idea that has been systematically evaluated and refined over time. Scientists test their theories by repeating experiments or observations that led to them. Therefore, the theory of evolutionary theory has been repeatedly confirmed as well as the related theories of Copernican theory, atomic theory, and germ theory.

What is the Process of Evolution?

The process of evolution is a gradual change in the proportions of genetically different individuals within a species over time. This is the result of natural selection, 에볼루션게이밍 which favors those who are more adapted to their environment. The individuals who are more adaptable have a greater chance of survival and reproduction. As more people live and reproduce their genes become more prevalent in the population. This process is sometimes referred to as "survival for the fittest."

According to the theory of evolution the mutations that cause genomic variation are what drives evolutionary change. These mutations can occur at random or under the influence of the environment. When mutations occur randomly and occur in a random manner, the frequency of the allele will vary from generation to generation. If a mutation is beneficial it will increase the frequency of alleles which causes the allele to be spread across the population.

As time passes, these changes in the frequencies of alleles can lead to the formation of new species. The new species will evolve and develop into newer forms. This is known as macroevolution. The development of new species is usually a result of changes in the environment which make certain resources available or creates new environmental problems. For instance, the rise of finches on the Galapagos Islands is a result of the availability of different foods and the need to protect themselves from predators.

In a broader sense, evolution is defined as any change that occurs in the characteristics of organisms over time. This change can be small or even the creation of a new coloration or large, such as the creation of a new organ.

Scientists who accept the theory of evolution generally recognize the importance of genetic change in the process that causes evolution. They also agree that the process of evolution happens over a long time, usually millions of years. However, they differ over 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 the evidence to prove 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 which show the evolution of organisms over time. Similarities between living organisms as well as embryology, biogeography, and genetics are evidence.

The most important proof of evolution is in the evolutionary tree, which shows how species are related. Another source of evidence is homologous structures, which share a similar structure in different species, but perform distinct functions, such as the wings of birds and bats. The fact that different species develop and adapt to the same environment is also evidence of evolution. For instance, arctic-foxes and Ptarmigans sport white seasonal pelts that blend into the snow and ice. This is a form of convergent evolutionary process, which suggests that the species have shared ancestors.

Another piece of evidence is vestigial structures, which are unused parts of an organism which could serve a purpose in a distant ancestor. The human appendix for instance is an odour from an organ that once used to digest food. These structures tend to shrink in size when they are no longer utilized which is a process referred to as natural selection.

Scientists have also collected evidence for evolution by observing and experimenting. The evidence for evolution is divided into six categories: directly visible small-scale changes, biogeographic patterns, comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that evolution of life has occurred.

While many people are misinformed about the theory of evolution, it is an empirical fact. It isn't only a theory, it is a powerful collection of decades of observation and accumulated 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 know the story of life on Earth. This information will allow scientists to better understand how to avoid future global catastrophes, and how to use the resources on our planet. This information will also help us better serve the needs and desires of all the people living on this planet.
