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, genetics and palaeontology.
However, the study of evolution is often controversial, and the resulting misinformation can confuse people regarding its basic concepts. This site clarifies the most fundamental concepts.
What is Evolution?
Modern evolutionary theory is based on the gradual and cumulative changes that occur in populations over time. These changes are the result of natural selection, which increases the amount of organisms that have beneficial traits that allow them to survive and reproduce in a particular environment. In turn, these organisms leave more offspring than those that do not have the beneficial characteristics. This can result in a genetic mutation that could eventually lead to new species.
The term "evolution" is often associated with the notion of "survival of the fittest" which implies that individuals who are best adapted to a particular set of environmental conditions will have an advantage over those who aren't well-adapted. However, this is only one of many ways that evolution could occur.
Another common way the word evolution is used is to suggest that a species will eventually progress from one state of being to the next one. This view of evolution is known as anagenetic or cladogenesis. This theory is not supported by the definition of evolution that is scientifically accepted. The theory of evolution that is based on science changes focuses on the changes that occur in populations over time. These changes are the result mutations that produce natural selection and genomic variation.
Charles Darwin was one of the scientists who supported this view. Others, notably Alfred Russel Wallace, who came up with the macroevolution theory, believed that this was the only way the higher forms of life could have evolved from the lower forms.
In order for a concept to be considered a theory, it has to be able to stand up to rigorous testing and evidence. The evidence of evolution has stood the test of time and has been supported by numerous studies in various scientific disciplines, ranging from biology to geology to chemistry to astronomy. In fact evolution is considered to be one of the cornerstones of science today and is backed by the majority of scientists across the globe. Many people are misinformed about the nature of the evolution theory, especially how it relates to religion.
What is the Theory of Evolution?
Evolution is an explanation for the way living things change over time. It is based on a range of well-established observations that show that more offspring are often produced than can possibly survive and that individuals differ from one another in their physical characteristics (phenotype); that different traits have different rates of reproduction and survival; and that traits can be passed on to future generations. These observations are backed by the increasing body of evidence from molecular biology, palaeontology, functional morphology, climatology and

The theory of evolution by natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the mid-19th century to explain the reason that organisms are adapted to their biological and physical environment. It is the most well-supported and tested theory in the field of science. Its predictions have been proved out by the fact that, for instance complex organisms are more likely to have less genetic mutations than simpler ones. The more successful an organism becomes in terms of its longevity and reproducing, the more likely it will transmit its genes to the next generation.
Some people are against evolution because they think it implies there is no purpose to life. However, a lot of scientists who are also religious believers, such as the prominent Cambridge palaeontologist Simon Conway Morris, believe that evolution is not just compatible with belief in God but also enhances it (BioLogos 2014).
In actual fact, a significant number of highly trained 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 them have contributed to the understanding of a wide variety of phenomena, like phylogenetics, genomics, and the formation and purpose of fossils.
The word "theory",

Fleshwind14.Bravejournal.Net) which is often used incorrectly refers to scientific hypotheses that have been tested and refined over a period of time. Scientists test hypotheses through repeating the experiments or observations that led them to the conclusion. So the theory of evolution theory has been repeatedly confirmed along with the related theories of Copernican theory, atomic theory, and germ theory.
What is the Process of Evolution?
The process of evolution is the gradual shift over time in the percentage of genetically distinct individuals within a specific species. This change is a result of natural selection, which favors 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 people survive and reproduce, their genes become more common in the general population. This is sometimes referred to as "survival for the strongest."
According to the theory of evolution, the mutations that produce genetic variation are the basic basis for evolutionary change. These mutations may 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 can 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 lead to new species as time passes. The new species will grow and evolve into new 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 problems. The development of finches in the Galapagos Islands, for example, is due to the availability of new foods and the necessity to defend themselves against predators.

Scientists who believe in evolution theory generally agree that genetic change is important in the process of generating evolution. They also acknowledge that evolution is a process that happens in time, typically over millions of years. They differ on the importance of different factors that could speed up or slow down the 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 that the evidence to prove it is overwhelming.
What is the Evidence of Evolution?
In the decades since Darwin's time, scientists have collected evidence that supports 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 evolutionary tree is the most effective method to prove the existence of evolution. It shows how different species are related. Homologous structures are another source of evidence. They share a similar structure, but they perform different functions in different species, for instance, the wings of a bat or bird. Evolution is evident in the way that different species adapt and develop to similar environments. For instance, arctic-foxes and Ptarmigans have white pelts during the winter months that blend into the snow and ice. This is a type of convergent evolutionary, which suggests that the species has common ancestral ancestors.
Vestigial structures are another piece of evidence. They are the remains of an organism that may have served some purpose in the past. The human appendix for instance is a remnant of an organ that was once used to digest food. Natural selection causes the structures to shrink when they are no longer utilized.
Scientists have also gathered additional evidence for evolution through observation and experimentation. The evidence for evolution is divided into six categories: directly observable small-scale changes, biogeographic patterns and comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that the evolution of life took place.
Although many people have misconceptions about the theory of evolution it is an established fact. It is not a theory, but a significant collection that is based on decades of observation. Whatever people believe or disbelieve about the theory of evolution scientists continue to study and gather new information to better know the story of life on Earth. This knowledge will allow scientists to better understand how to avoid future catastrophes on the planet, and how best to make use of the resources available on our planet. This information will also help us better meet the needs and desires of all the people living on our planet.
