The Evolution Site

The theory of evolution by natural selection is the unifying force of modern biology. It brings together disciplines such as microbiology, palaeontology, and genetics.

However, the study of evolution is often controversial and the misinformation that results can confuse people about the fundamentals of evolution. This site explains the fundamental concepts.

What is Evolution?

Modern evolutionary theory is based on the gradual and cumulative changes that happen in 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 live and reproduce in specific environments. In turn, these organisms produce more offspring than those that do not have the beneficial traits. This leads to an alteration in genetics that could eventually lead to the formation 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 environment will have an advantage over those who aren't adapted to the environment. In reality this is just one of many ways that evolution could occur.

Another common way the word evolution is used to suggest that a species will inevitably change from one state to the next one. This view of evolution is called anagenetic or cladogenesis. The scientific definition of evolution does not support this view. Instead the theory of evolution that is scientifically based is based on the changes that occur within populations over time, and these changes are the result of genetic mutations and natural selection.

Charles Darwin was one of the scientists who supported this theory. Others, such as Alfred Russel Wallace, who created the macroevolution theory and believed that this was the only way the higher forms of life could be derived from lower ones.

A concept must be able stand against rigorous tests and 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 biology to geology, from astronomy to chemistry. In actual fact evolution is regarded as one of the cornerstones of science today, and it is backed by the vast majority of scientists worldwide. Many people are misinformed about the nature of the theory of evolution, especially how it relates to religion.

What is the Theory of Evolution (Evolutionary Theory)?

Evolution is the scientific explanation for how living things change over time. It is based on few known facts: that more offspring are born than can be surviving as individuals differ in their physical characteristics and that they can transmit traits to the next generation. These observations are supported by the increasing amount of evidence from molecular biology, palaeontology climatology, functional morphology and geology.

Charles Darwin and Alfred Russel Wallace independently developed the theory of evolution through selection in the mid-19th Century as an explanation why organisms adapt to their physical and 에볼루션 카지노 사이트바카라 에볼루션사이트 (try this site) biologic environments. It is the most widely supported and tested theory in science. Its predictions were proved by the fact that for 에볼루션 바카라 체험사이트 (marvelvsdc.Faith) instance, more complex organisms have less genetic mutations. Additionally the more successful an organism is at reproduction and survival and reproducing, the more likely it will be to pass its genes to future generations.

Some people are against evolution because they think it suggests that there is no reason for existence. 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 even enhanced by it.

Many highly qualified evolutionary biologists have been involved in the development and testing the theory of evolution, including several revered evangelical Christian leaders. Many of these researchers contributed to the understanding of a broad range of phenomena, including genomics and phylogenetics and also the formation and function fossils.

The term "theory", which is often used incorrectly is a reference to a 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 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 the gradual change over time in the ratio of genetically distinct individuals within a specific species. This change is a result of the natural selection of those who are more adapted to their environment. The people who are more adaptable have higher chances of reproduction and survival. As more of these individuals survive and reproduce their genes become more common in the general population. This is sometimes referred to as "survival of the fittest."

According to the theory of evolution the mutations that result in genetic variation are the basic material of evolutionary change. These mutations may occur randomly or be affected by the environment. When mutations are random, 에볼루션사이트 the frequencies of the resulting alleles may differ from generation to generation. When a mutation is beneficial it will increase the frequency of alleles, causing 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 may grow and evolve into newer forms. This is known as macroevolution. The formation of new species is often due to changes in the environment, which makes certain resources available or creates new environmental challenges. The evolution of finches in the Galapagos Islands, for example is due to the availability of new food and the necessity to defend themselves from predators.

In a larger sense it is any change that takes place in the characteristics of organisms over time. This change can be subtle, like the development of a new color or a dramatic change, 에볼루션사이트 such as the formation of an organ.

Scientists who accept the theory of evolution generally agree on the significance of genetic change in generating evolution. They also acknowledge that the process of evolution happens over a long period of time, usually millions of years. They differ on the importance of different factors that can accelerate or slow down the process. For instance the role played by sexual selection, environmental pressures, and mutation bias. Despite these differences most scientists still believe that evolution is real and that the evidence in support of this is overwhelming.

What is the Evidence of Evolution?

Since Darwin's time, scientists have gathered evidence to support Darwin's theory of evolution. A portion of this evidence is derived from fossils which demonstrate the changing features of organisms through time. Similarities between living organisms as well as embryology, biogeography, and genetics are further evidence.

The main proof of evolution is found in the evolutionary tree, which illustrates how different species are connected. Homologous structures are another proof. They share a similar structure but serve different purposes in different species, for instance, the wings of a bat or bird. The fact that different species develop and adapt to a similar environment is also a sign of evolution. For example, arctic-foxes and Ptarmigans sport white pelts during the winter months that blend in with the snow and ice. This is a kind of convergent evolutionary process which suggests the species shared ancestors.

The vestiges of structures are another source of evidence. These are a part of an organism which may have served some purpose in the distant past. The human appendix for instance is an odour from an organ that was used to digest food. Natural selection causes the structures to shrink when they cease to be used.

Scientists have also collected evidence of evolution through observation and experimenting. The evidence for evolution can be grouped into six different categories: changes that can be observed at a small scale biogeographic distributions, comparative anatomies fossil records and genetics. Each of these provides compelling evidence that the evolution of life has occurred.

Many people have misconceptions about the theory of evolution. However, it is an established fact. It is not a theory but a significant collection of evidence built on years of observation. Whatever people believe or deny about the theory of evolution scientists continue to study and discover new information in order to further comprehend the evolution of life on Earth. This information will allow scientists to better understand how to avoid future catastrophes on the planet, and how to use the resources available on our planet. This information will also help us better serve the needs and desires of the people living on our planet.
