The Evolution Site

The theory of evolution based on natural selection is the unifying force of modern biology. It ties together disciplines as diverse as genetics, microbiology, and palaeontology.

However, the study of evolution is often controversial and the resultant misinformation can confuse people regarding the fundamentals of evolution. This site clarifies essential concepts.

What is Evolution?

Modern evolutionary theory focuses on the gradual and cumulative changes that happen in populations over time. These changes are the result of natural selection. This is a process which increases the number of organisms that have beneficial traits, which help them to thrive and reproduce in certain environments. In turn, these organisms produce more offspring than those who do not have the beneficial characteristics. This causes the genetic changes that can eventually lead to the development of new species.

The term "evolution", is often associated with "survival-of-the fittest" which implies that people who are more adaptable to specific environmental conditions will have a distinct advantage over those less well adapted. This is just one of many ways that evolution can happen.

Another common way the word evolution is used to suggest that a species will inevitably move from one state to the next state of being. This type of view of evolution could be described as anagenetic or cladogenesis. The definition of evolution in science does not support this view. The scientific theory of evolutionary change focuses instead on the changes that occur in populations over time. These changes are the result of mutations that result from natural selection and genetic variation.

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

To be able to be referred to as a theory, it has to be capable of surviving rigorous tests and evidence.  에볼루션 무료체험  has stood the test of time, and has been supported in many scientific disciplines, from geology to biology, the sciences of astronomy to chemistry. In reality evolution is considered to be one of the foundations of science today, and is supported by the vast majority of scientists around the world. Many people are misinformed about the nature of evolution theory and how it connects with religion.

What is the Theory of Evolution (Evolutionary Theory)?

Evolution is the scientific explanation for the way living things change over time. It is based on a variety of well-established observable facts that show that more offspring are often produced than could possibly survive and that individuals differ from each other in their physical characteristics (phenotype); that different traits confer varying rates of reproduction and survival and reproduction; and that these traits can be passed on to the next generation. These observations are supported by an increasing body of evidence from molecular biology, palaeontology and 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 an explanation why organisms adapt to their biological and physical environments. It is currently the most well-supported and widely-tested theory in the field of science. Its predictions were proved by the fact that for instance, more complex organisms have fewer genetic mutations. The more successful an organism becomes in terms of survival and reproducing, the more likely it will transfer its genes to future generations.

Some people oppose evolution because they believe it implies there is no purpose for life. However, a lot of scientists who are also religious believers, such as the prominent Cambridge palaeontologist Simon Conway Morris, believe that evolution isn't just compatible with faith in God but is enhanced by it (BioLogos 2014).

Many highly qualified evolutionary biologists have been involved in developing and testing the theory of evolution, which includes some respected evangelical Christian leaders. Many of these scientists 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 misinterpreted refers to scientific hypotheses that have been tested and refined over time. Scientists test their theories by repeating the experiment or observations that have led to them. Thus the theory of evolutionary theory has been repeatedly confirmed, as have the corresponding theories of Copernican theory, atomic theory, and germ theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the proportions of genetically different individuals within a particular species over time. This change is a result of natural selection of individuals who are more adapted to their environment. The individuals who are more adapted have better chances of reproduction and survival. As more people survive and reproduce, their genes become more prevalent in the population. This is sometimes referred to as "survival of the fittest."

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

Over time, these changes in allele frequencies could result in the creation of new species. The new species can then continue to evolve and become newer forms. This is a process known as macroevolution. The creation of a new species is often due to changes in the environment which provide certain types of resources available or create new environmental problems. The evolution of finches in the Galapagos Islands, for example is due to the availability of new food and the necessity to defend themselves against 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 dramatic, like the development of an organ.

Scientists who accept the theory of evolution generally agree on the significance of genetic changes in the process of generating evolution. They also acknowledge that the process of evolution happens over a long period of time, typically millions of years. They differ in the importance of various factors that can accelerate or slow down this process. For instance the role played by sexual selection, environmental pressures, and mutation bias. Despite these differences, the majority of scientists believe that evolution is happening and that the evidence for this is overwhelming.

What is the Evidence of Evolution?

Since Darwin's time, scientists have gathered evidence that supports Darwin's theory of evolution. Some of this evidence comes from fossils which reveal the changing traits of living organisms over time. Similarities between living organisms as well as embryology, biogeography, and genetics are also evidence.

The evolutionary tree is the best way to prove evolution. It shows how species are closely related. Another evidence source is homologous structures, which have similar structures in different species but perform distinct functions such as the wings of birds and bats. The fact that different species evolve and adapt to the same environment is another sign of evolution. For instance, arctic foxes and Ptarmigans wear white pelts during the winter months which blend with snow and ice. This is a type of convergent evolution that suggests that the species has common ancestors.

Another evidence point is the existence of vestige structures, which are unutilized organs which could have served a purpose in the distant ancestors. For example the human appendix is a vestige of a once-used organ that was used to digest food. These structures tend to shrink in size once they are no longer utilized which is a process referred to as natural selection.

Scientists have also collected evidence for evolution through observation and experimenting. Evidence for evolution is grouped into six categories: directly visible small-scale changes, biogeographic distribution as well as comparative anatomy, fossil record, genetics, and classification. Each of these categories provides convincing evidence for the evolution of life.

Many people have misconceptions regarding the theory of evolution. But, it's a fact. It is not a theory but rather a powerful collection that is founded on decades of observation. Scientists continue to collect and analyze new data to better understand the evolution of Earth's evolution regardless of whether people believe in the theory of evolution or not. This information will aid scientists understand how to prevent future global catastrophes and also how to best utilize our planet's resources. It will also allow us to better meet the needs of the people living on the planet.
