The Evolution Site

The theory of evolution through natural selection is the defining force of modern biology. It ties together disciplines that are as diverse as genetics microbiology, and the study of palaeontology.

However the study of evolutionary theory is often controversial, and the misinformation that results can confuse people about its basic concepts. This site clarifies the most fundamental 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 that have beneficial traits, which allow them to live and reproduce in certain environments. The organisms that have these traits produce more offspring as a result of the positive traits. This leads to an alteration in genetics that could eventually lead to the creation of new species.

The term "evolution" is often ascribed to the notion of "survival of the fittest," which implies that people who are most well-adapted to a particular set of environmental conditions will have an advantage over those who are not well-adapted. In actuality it is only one of many ways that evolution can occur.

Another way that the term "evolution" is used to suggest that a species will eventually change from one state to the next state of being. This type of view of evolution could be described as anagenetic or cladogenesis. This is not backed by the scientific definition of evolution. Instead the theory of evolution that is scientifically based is based on the changes that take place within populations over time and these changes are caused by mutations that produce genomic variation and natural selection.

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


A concept must be able stand up to rigorous tests and evidence in order to be considered a theory. Evolution has stood the test of time, and has been backed by numerous scientific disciplines ranging from biology to geology, from astronomy to chemistry. Evolution is a fundamental concept in science and is backed by the majority of scientists across the world. However, there are many misconceptions about the nature of the theory of evolution, specifically how it relates to religion.

What is the Theory of Evolution (Evolutionary Theory)?

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

The theory of evolution through natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the mid-19th century to explain how organisms adapt to their physical and biological environments. It is now the best-supported and most extensively tested theory in the field of science. Its predictions were confirmed by the fact that for instance, more complex organisms have less genetic mutations. In addition, the more successful an organism is at surviving and reproducing in its ability to reproduce, the more likely it will be to pass its genes to the next generation.

Some people are against evolution because they believe it implies there is no reason for existence. Many scientists who are religious believers such as the Cambridge palaeontologist Simon Conway Morris (BioLogos, 2014) believe that evolution is compatible with faith in God and even enhanced by it.

In actual fact, a significant number of highly qualified evolutionary biologists, some of who are renowned evangelical Christian leaders are involved in the creation and testing of the theory of evolution. Many of them have contributed to the understanding of a vast variety of phenomena, including phylogenetics and genomics and the formation and role of fossils.

The word "theory" is often used in a wrong sense to mean a guess or speculation, when in fact it refers to a scientific idea that has been systematically tested and refined over time. Scientists test hypotheses through repeating the experiments or observations that led them to them. Therefore, the theory of evolution has been repeatedly proven out as have the corresponding theories of Copernican, germ and atomic theory.

What is the Process of Evolution?

The process of evolution is the gradual change over time in the proportion of genetically distinct individuals within a certain species. This is the result of natural selection of individuals who are better adapted to their environment. The better-adapted individuals have a better chance of survival and reproduction. As more of these individuals survive and reproduce their genes become more common within the population. This process is sometimes called "survival for the fittest."

According to the theory of evolution, the mutations that produce genomic variation are the raw material for evolution. These mutations could occur at random or be influenced by the environment. If mutations occur in a random manner, the allele frequencies may vary from generation to generation. When a mutation is beneficial it can increase the frequency of the allele which causes the allele to spread throughout the population.

As time passes, these changes in the frequencies of alleles can result in the creation of new species. The new species will then grow and evolve into new forms. This is a process called macroevolution. The formation of a new species is often caused by changes in the environment that provide certain types 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 to defend themselves from predators.

In a wider sense the term "evolution" can be described as any change in the characteristics of living organisms over time. The change could be subtle, like the development of new coloration or dramatic, like the formation of an organ.

Scientists who believe in the theory of evolution 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 long period of time, typically millions of years. However, they differ on the role of various factors that speed up or slow down the process, including the role of environmental pressures, sexual selection and mutation bias. Despite these differences scientists believe that evolution has happened and that evidence for this is overwhelming.

What is the Evidence of Evolution?

Since Darwin's time, scientists have collected evidence to support his theory of evolution. The evidence comes from fossils which show the evolution of living organisms over time. Other evidence is found in the similarities between living organisms embryology, biogeography genetics and comparative anatomy.

The evolutionary tree is the best method of proving evolution. It shows how different species are closely related. Homologous structures are another proof. They have a similar structure but serve different purposes in different species, such as 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 example, arctic-foxes and Ptarmigans wear white seasonal pelts which blend with snow and ice. This is a kind of convergent evolution, which suggests that the species has common ancestral ancestors.

Another evidence point is the existence of vestige structures, which are unused parts of an organism that could serve a purpose in a distant ancestor. The human appendix, for instance is a remnant of an organ that was once used to digest food. These structures tend to shrink in size as they are no longer utilized, a process known as natural selection.

Scientists have also gathered evidence for evolution by observing and testing. The evidence for evolution can be divided 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 convincing evidence that evolution of life has taken place.

Although many people have misconceptions about the theory of evolution It is an empirical fact. It isn't simply a flimsy theory. It is a powerful collection of years of observations and data that has been tested and proven. No matter what people believe or disbelieve about the theory of evolution scientists continue to research and gather new information to better know the story of life on Earth. This information will allow scientists to better understand how we can avoid future catastrophes on the planet, and how to use the resources of our planet. This will allow us to better serve the needs of all the people living on this planet.
