The Evolution Site

The concept of natural selection as the basis of evolution is the unifying force in modern biology. It connects disciplines as diverse as genetics, microbiology and Palaeontology.

However the study of evolutionary theory is often controversial and the resultant misinformation can confuse people regarding its fundamentals. This Web site helps explain the most important concepts.

What is Evolution?

The modern conception of evolution focuses on the gradual, cumulative changes that occur within populations over time. These changes are the results of natural selection. This is a process which increases the number of organisms with beneficial traits, which allow them to live and reproduce in specific environments. In turn, these organisms leave more offspring than those that don't possess the beneficial traits. This results in the genetic changes that can eventually lead to the formation of new species.

The term "evolution" is frequently associated with the idea of "survival of the strongest," which implies that those individuals who are best adapted to a particular environment will have an advantage over those who aren't adapted to the environment. However, this is only one of the many ways in which evolution can occur.

Another common way the term "evolution" is used to suggest that a species will invariably progress from one state of being to the next one. This type of view of evolution is referred to as anagenetic or cladogenesis. This view is not supported by the definition of evolution that is scientifically accepted. Instead the theory of evolution that is scientifically based is based on the changes that occur in populations over time and these changes are caused by genetic mutations and natural selection.

Some scientists, including the great Charles Darwin, advocated this view of evolution. Others, including Alfred Russel Wallace, who developed the theory of macroevolution, believed that this was the only way the higher forms of life could be derived from lower forms.

A concept must be able stand up to rigorous tests and evidence in order to be considered as a theory. The evidence of evolution has stood up to the test of time and has been backed by a myriad of studies across various scientific disciplines, from biology to geology to chemistry to astronomy. In reality evolution is regarded as one of the fundamental tenets of science today, and it is supported by the majority of scientists across the globe. However, there are many misconceptions about the theory of evolution, and particularly how it relates to religion.

What is the Theory of Evolution?

Evolution is an explanation in science of the way living things change over time. It is based on a variety of well-established and observable facts that show that more offspring are created than are likely to survive; that individuals differ from each other in their physical characteristics (phenotype) and that various traits have different rates of survival and reproduction and can be passed on to the next generation. These observations are backed up by a growing body of evidence derived from molecular biology, palaeontology climatology functional geology, morphology.

The theory of evolution through natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the late 19th century as an explanation for why organisms are adapted to their biological and physical environments. It is the most well-supported and tested theory in the field of science. Its predictions have been borne out by the fact that, for instance complex organisms are more likely to have less genetic mutations than simpler ones. Additionally the more successful an organism is in reproduction and survival in its ability to reproduce, the more likely it will be to pass its genes to future generations.

Some people object to evolution based on the belief that it implies that there is no meaning to life. However, many scientists who are also religious believers like the famous Cambridge Palaeontologist Simon Conway Morris, believe that evolution isn't just compatible with faith in God but is enhanced by it (BioLogos 2014).

In actual fact, a significant number of highly qualified evolutionary biologists, including a few who are renowned evangelical Christian leaders have been involved in the creation and testing of the theory of evolution. Many of these researchers contributed to the understanding a wide range phenomena, including genomics and phylogenetics, as well as the formation and function of fossils.

The term "theory", which is often used incorrectly, refers to a scientific hypothesis that has been tested and refined over time. Scientists test hypotheses by repeating the experiments or observations that led them to the conclusion. Therefore, the theory of evolution has been repeatedly proven out as have the corresponding theories of Copernican, germ theory, and atomic theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the genetic makeup of different individuals within a species over time. This change is a result of natural selection, which favors individuals who are better adapted to their environment. The people who are more adaptable have better chances of reproduction and survival. As more of these people survive and reproduce their genes are more prevalent within the population. This is sometimes called "survival of the fittest."

According to theories of evolution the causes of mutations that result in genomic variation are what drives evolutionary change. These mutations can occur at random or be affected by the environment. If mutations occur in a random manner and occur in a random manner, the frequency of the allele can vary from generation-to-generation. However, when a mutation is beneficial it increases the frequency of the allele, which causes it to spread through the population.

Over time, these changes in allele frequencies could lead to the formation of new species. The new species could continue to evolve and become newer forms. This process is called macroevolution. The development of an entirely new species is typically due to changes in the environment which make certain kinds of resources available or create new environmental challenges. For instance, the development of finches on the Galapagos Islands is a result of the availability of different food sources and the need defend themselves from predators.

In a broader context the term "evolution" can be described as any change in the characteristics of living organisms over time. The change could be minor like the development of a new coloration or large, such as the creation of a new organ.

Scientists who believe in evolution theory generally believe that genetic change is essential in the process of generating evolution. They also acknowledge that the process of evolution takes place over a lengthy period of time, typically 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 are still convinced 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 is gathered from fossils which show the evolution of organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography, and genetics are further evidence.

The evolutionary tree is the best method of proving evolution. It shows how different species are related. Homologous structures are another proof. They share a common structure but perform different functions in different species, like the wings of a bat or bird. The fact that different species evolve and adapt to a similar environment is also evidence of evolution. For instance, arctic foxes and ptarmigans grow white fur coats that blend into snow and ice. This is a form of convergent evolution, which suggests that the species has common ancestral ancestors.

Vestigial structures are another piece of evidence. These are a part of an organism that may have served some purpose in the past. For  에볼루션 룰렛  is remnants of an earlier organ used to digest food. Natural selection is a process that causes these structures to shrink as they are no longer utilized.

Scientists have also gathered other evidence of evolution via observation and experimentation. The evidence for evolution can be divided into six categories: directly observed small-scale changes, biogeographic distribution as well as comparative anatomy, fossil record, classification and genetics. Each of these categories provides convincing evidence for the evolution of life.

Although many people have misconceptions about the theory of evolution, it is an established fact. It is not a theory but rather a powerful collection that is based on decades of observation. Whatever people believe or don't believe about the theory of evolution scientists continue to research and collect new data to better comprehend the evolution of life on Earth. This information will allow scientists to better understand how to prevent future global catastrophes and how best to make use of the resources of our planet. It will also enable us to better meet the needs of the people living on this planet.
