The Evolution Site

The concept of natural selection as the basis of evolution is the central force in the current biology. It connects disciplines such as genetics, microbiology and the study of palaeontology.

The study of evolution can be controversial and the misinformation that results can lead to confusion over 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 happen in populations over time. These changes are the result of natural selection, a process that increases the amount of organisms that have traits that are beneficial and help them survive and reproduce in a specific environment. These organisms produce more offspring because of the positive characteristics. This can result in a genetic mutation which could eventually lead to the creation of new species.

The term "evolution" is frequently associated with the idea of "survival of the fittest" which implies that people who are the most adapted to a specific set of environmental conditions will be more successful than those who aren't well-adapted. This is just one of many ways that evolution could happen.

Another popular way to use the word evolution is to suggest that a species can change from one state to the next. This theory of evolution is referred to as anagenetic or cladogenesis. This theory is not supported by the definition of evolution that is scientifically accepted. Instead, the scientific theory of evolution focuses on changes that take place within populations over time, and these changes are the result of mutations that produce genomic variation and natural selection.

Some scientists, such as the great Charles Darwin, advocated this theory of evolution. Others, notably Alfred Russel Wallace, who came up with the macroevolution theory, believed that this was the only way that the higher forms of life could be derived from lower forms.

In order for a concept to be referred to as a theory, it must be capable of standing up to rigorous testing and evidence. The evidence for evolution has stood the test of time and has been supported by numerous studies in many scientific disciplines, ranging from geology to biology to astronomy. Evolution is a cornerstone of science and is believed by a majority of scientists around the globe. Many people have misconceptions regarding the nature of the theory of evolution particularly how it is connected with religion.

What is the Theory of Evolution?

Evolution is an explanation in science of how living things change over time. It is based upon a few established facts: that more offspring are produced than can survive, that individuals differ in their physical traits and they can transmit traits to the next generation. These findings are backed by a growing body of evidence derived from molecular biology, palaeontology climatology functional geology and morphology.

Charles Darwin and Alfred Russel Wallace independently conceived the theory of evolution by selection in the middle of the 19th century as a way to explain how organisms are adapted their biological and physical 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 are less susceptible to genetic mutations. Additionally, the more successful an organism is in reproduction and survival and reproducing, the more likely it is to pass on its genes to future generations.

Some people are against evolution because they believe 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 is not just compatible with belief in God but can be enhanced by it (BioLogos 2014).

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

The word "theory", 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 them. So, the theory of evolutionary theory has been repeatedly confirmed as have the corresponding theories of Copernican theory as well as 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 particular species. This change is the result of natural selection of individuals that are more well-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 become more common in the general population. This process is sometimes referred to as "survival for the fittest."

According to 에볼루션사이트 of evolution the mutations that result in genetic variation are the basic basis for evolutionary change. These mutations can occur at random or be affected by the environment. When mutations occur at random and the frequencies of alleles can vary from generation-to-generation. However, when an alteration is beneficial, it will increase the frequency of the allele, causing it to spread throughout the population.

Changes in the frequency of alleles can lead to new species in the course of time. The new species will develop and evolve into new forms. This process is known as macroevolution. The creation of a new species is often caused by changes in the environment that allow certain kinds of resources to become available or create new environmental problems. For example, the evolution of finches on the Galapagos Islands is a result of the abundance of food sources and the need to defend themselves from predators.

In a wider sense it is possible to define evolution as any change in the nature of living organisms over time. The change could be subtle, such as the development of new colors or a dramatic change, such as the formation of an organ.

Scientists who believe in the theory of evolution generally agree that genetic changes are essential in creating evolution. They also agree that evolution is a process that takes place over time, typically over millions of years. They differ on the importance of different factors that could speed up or slow down this process. For example, the role of sexual selection, environmental pressures, and mutation bias. Despite these differences, most scientists believe that evolution has happened and the evidence to prove this is overwhelming.

What is the Evidence of Evolution?

Throughout the years since Darwin's time, scientists have collected evidence to support his theory of evolution. The evidence comes from fossils that show the evolution of living organisms over time. Another evidence comes from similarities between living organisms embryology, biogeography genetics and comparative anatomy.

The primary evidence of evolution is in the evolutionary tree, which demonstrates how species are related. Another source of evidence is homologous structures, which have a similar structure in different species but perform distinct functions such as the wings of birds and bats. Evolution is evident in that different species adapt and develop to similar environments. For instance, arctic-foxes and ptarmigans grow seasonal white pelts that blend into snow and ice. This is a type of convergent evolution that suggests that the species have common ancestral ancestors.


Another piece of evidence is the existence of vestigial structures. These are unusable parts of an organism that could serve a purpose in the distant ancestor. For instance the human appendix is a vestige of a once-used organ used to digest food. Natural selection causes these structures to shrink as they cease to be used.

Scientists have also gathered additional evidence of evolution through observation and experimentation. Evidence for evolution is grouped into six categories: directly observed small-scale changes, biogeographic patterns and comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that evolution of life took place.

While many people are misinformed about the theory of evolution it is an established fact. It isn't only a theory, it is a mighty collection of decades of observation and accumulated data that has been proven and tested. Scientists continue to collect and analyze new data to better understand the evolution of Earth's evolution regardless of whether or not people believe in the theory of evolution or not. This knowledge will allow scientists to better understand how we can avoid future global catastrophes, and how best to make use of the resources on our planet. It will also enable us to better meet the needs of people on this planet.
