The Evolution Site

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

The study of evolution can be controversial, and the misinformation that results can cause confusion about its basic concepts. This Web site helps clarify essential concepts.

What is Evolution?

The modern understanding of evolution is based on the gradual and cumulative changes that happen within populations over time. These changes are the result of natural selection. This is a process that increases the number of organisms that have beneficial traits, which enable them to survive and reproduce in certain environments. The organisms that have these traits produce more offspring as a result of the positive traits. This could result in a genetic mutation which could eventually lead to new species.

The term "evolution", is often associated with "survival-of-the fittest" which means that those who are more adjusted to certain conditions will have an advantage over those who are less well adapted. This is just one of many ways that evolution can occur.

Another popular way in which the term "evolution" is used to suggest that a species will invariably progress from one state of being to the next one. This view of evolution can be described as anagenetic or cladogenesis. This theory is not supported by the scientific definition of evolution. The scientific theory of evolutionary change focuses instead on the changes that occur in populations over time. These changes are the result mutations which result in natural selection and genetic variation.

Charles Darwin was one of the scientists who backed this idea. Alfred Russel Wallace who developed the macroevolution theory believed this was the only way in which the higher forms of living could have evolved.

For a concept to be called a theory, it has to be capable of surviving rigorous testing and evidence. Evolution has stood the test of time, and has been proven to be valid in numerous scientific disciplines ranging from biology to geology, chemistry to astronomy. In fact, evolution is accepted as one of the fundamental tenets of science today and is backed by the majority of scientists across the globe. Many people are misinformed about the nature of the theory of evolution and how it connects to religion.

What is the Theory of Evolution?

Evolution is the scientific explanation of how living things change over time. It is based on few well-established facts: that many more offspring are produced than can survive as individuals differ in their physical traits and they can transmit traits to the next generation. These observations are backed up by a growing amount of evidence derived from molecular biology, palaeontology climatology functional geology and morphology.

Charles Darwin and Alfred Russel Wallace independently conceived the theory of evolution through selection in the mid-19th century as a reason why organisms adapt to their biological and physical environments. It is the most well-supported and validated theory in science. Its predictions were proved by the fact, for example that more complex organisms have less genetic mutations. The more successful an organism is in terms of its longevity and reproducing the more likely it will pass its genes on to the next generation.

Some people are against evolution because they believe that it suggests that there is no purpose for life. However, a lot of scientists who are also religious like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with belief in God but is enhanced by it (BioLogos 2014).

Many highly qualified evolutionary biologists have been involved in constructing and testing the theory of evolution, including several revered evangelical Christian leaders. Many of these scientists contributed to the understanding of a wide range phenomena, including genomics and phylogenetics, as well as the formation and function fossils.

The term "theory" is sometimes used in a wrong sense to mean a guess or speculation however it actually refers to a scientific idea that has been thoroughly tested and refined over time. Scientists test hypotheses by repeating the experiments or observations that led them to their conclusions. The theory of evolution has been repeatedly tested out and so have the theories of Copernican, germ theory, and atomic theory.

What is the Process of Evolution?

The process of evolution is a gradual change in the proportions of genetically 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 people live and reproduce their genes become more prevalent in the general population. This process is sometimes called "survival for the strongest."

According to evolution theory the mutations that cause genomic variation are what drives evolution. These mutations can occur randomly or be affected by the environment. If mutations occur in a random manner and the frequencies of alleles will vary from generation to generation. If a mutation is beneficial, it can increase the frequency of the allele which causes the allele to be spread across the population.

Over time, these changes in allele frequencies can result in the creation of new species. The new species will evolve and develop into newer forms. This is a process called macroevolution.  에볼루션 무료체험  of a new species is usually caused by changes in the environment which provide certain types of resources available or create new environmental challenges. For instance, the development of finches in the Galapagos Islands is a result of the availability of various 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 characteristics of living organisms over time. The change could be subtle, like the development of new colors or dramatic, like the development of an organ.

Scientists who believe in the theory of evolution generally agree that genetic changes are essential in generating evolution. They also believe that evolution is a process that takes place in time, typically over a period of millions of years. However, they differ over the role of various factors in speeding or slowing the process, like the role of environmental pressures, sexual selection and mutation bias. Despite these differences, most scientists believe that evolution has happened and the evidence to prove this is overwhelming.

What evidence do we have to support evolution?

Throughout the years since Darwin's time, scientists have gathered evidence to support his theory of evolution. This evidence comes from fossils that show the evolution of organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography and genetics are also evidence.

The main proof of evolution is found in the evolutionary tree, which shows how different species are related. Homologous structures are another source of evidence. They share a common structure but serve different purposes in different species, like 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 instance, arctic-foxes and ptarmigans have seasonal white pelts that blend in with snow and ice. This is a kind of convergent evolution, which suggests that the species has common ancestors.

The vestiges of structures are another source of evidence. These are parts of an organism which may have served some purpose in the past. For instance, the human appendix is a vestige of a once-used organ used to digest food. Natural selection causes the structures to shrink when they are no longer utilized.

Scientists have also gathered additional evidence of evolution via observation and experimentation. The evidence for evolution can be divided into six different categories: changes that can be observed at small scales, biogeographic distributions, comparative anatomy, the fossil record and genetics. Each of these categories offers 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 a significant collection of evidence based on decades of observation. Scientists continue to collect and analyze new data to better understand the history 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 available on our planet. It will also allow us to better serve the needs of all the people living on the planet.
