The Evolution Site

The theory of natural selection as the basis of evolution is the unifying force in the field of modern biology. It ties together disciplines as diverse as genetics, microbiology, and Palaeontology.

The study of evolution may be controversial and the misinformation that comes from it can cause confusion about the fundamentals of evolution. This website helps to explain the most important concepts.

What is Evolution?

Modern evolutionary theory is based on the gradual and cumulative changes that take place in populations over time. These changes are caused by natural selection, a process that increases the amount of organisms that have beneficial traits that allow them to survive and reproduce in a specific environment. In turn, these organisms leave more offspring than those who do not have the beneficial traits. This can result in a genetic mutation that may eventually result in new species.

The term "evolution" is often ascribed to the notion of "survival of the fittest" which means that individuals who are best adapted to a specific set of environmental conditions will have an advantage over those who aren't adapted to the environment. In actuality, this is only one of the many ways that evolution could occur.

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

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

A concept must be able stand against rigorous tests and evidence in order to be considered as a theory. The evidence for evolution has withstood the test of time and has been supported by numerous studies in a wide range of scientific disciplines, ranging from biology to geology, 에볼루션 바카라 chemistry to astronomy. In actual fact evolution is considered to be one of the foundations of science today, and is supported by the vast majority of scientists worldwide. However, many people have misconceptions about the nature of the theory of evolution, and particularly how it relates to religion.

What is the Theory of Evolution (Evolutionary Theory)?

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

Charles Darwin and Alfred Russel Wallace independently conceived the theory of evolution by selection in the mid-19th Century as an explanation why organisms adapt to their biological and physical environments. It is today the most supported and 에볼루션 사이트 widely-tested theory in all of science. Its predictions were proven by the evidence that for instance, more complex organisms are less susceptible to genetic mutations. In addition, the more efficient an organism is in surviving and 에볼루션 카지노 reproducing and reproducing, the more likely it is to pass its genes to future generations.

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 believers such as the renowned Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with faith in God but is enhanced by it (BioLogos 2014).

In actual fact, a significant number of highly trained evolutionary biologists, some of who are respected evangelical Christian leaders are involved in the creation and testing of the theory of evolution. Many of these scientists contributed to the understanding of a broad range of phenomena, including phylogenetics and genomics, as well as the formation and function of fossils.

The term "theory" is sometimes used to refer to a speculation or guess however it actually refers to a scientific idea that has been rigorously evaluated and refined over time. Scientists test hypotheses through repeating the experiments or observations that led them to their conclusions. The theory of evolution has been repeatedly borne out, as have the related 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 is the result of the natural selection of individuals who are more adapted to their environment. The individuals who are more adapted have higher chances of reproducing and survival. As more people survive and reproduce, their genes are more common within the population. This is sometimes called "survival of the most fittest."

According to theories of evolution the causes of mutations that result in genetic variation are the primary reason for evolution. These mutations may occur at random, or under the influence of the environment. If mutations are random, the frequency of the resultant alleles could vary from generation to generation. However, when an alteration is beneficial it can increase the frequency of the allele, which causes it to spread throughout the population.

Changes in the frequency of alleles could lead to new species in the course of time. The new species could continue to evolve and become newer forms. This process is called macroevolution. The development of a new species is often caused by changes in the environment that make certain kinds of resources available or cause new environmental problems. The evolution of finches in Galapagos Islands, for example, is due to the availability of new foods and the necessity to defend themselves from predators.

In a larger sense the term "evolution" refers to any change that occurs in the traits of living organisms over time. This change can be subtle, like the development of new colors or a dramatic change, such as the development of an organ.

Scientists who accept evolution theory generally believe that genetic change is crucial in the process of the process of generating evolution. They also agree that the process of evolution takes place over a long period of time, often millions of years. However, they differ over the role of various factors in accelerating or retarding this process, such as the impact of environmental pressures, 에볼루션바카라사이트 sexual selection and mutation bias. Despite these disagreements, most scientists still believe that evolution is real and the evidence in support of this is overwhelming.

What is the Evidence of Evolution?

Throughout the years since Darwin's time, scientists have gathered evidence to support Darwin's theory of evolution. Some of this evidence comes from fossils which reveal the changing traits of organisms through time. Similarities between living organisms as well as embryology, biogeography, and genetics are further evidence.

The evolutionary tree is the most effective method of proving evolution. It shows how species are closely related. Another source of evidence is homologous structures, which share a similar structures in different species but serve different purposes such as the wings of bats and birds. Evolution is also evident in the fact that various species adapt and evolve to similar environments. For example, arctic-foxes and Ptarmigans wear white pelts during the winter months that blend into the snow and ice. This is a kind of convergent evolutionary, which suggests that the species have common ancestors.

Another source of evidence is the existence of vestige structures, which are unusable organs that could have served a function in a distant ancestor. The human appendix, for 에볼루션 코리아 example, is a vestige from an organ that once used to digest food. Natural selection is a process that causes these structures to shrink as they cease to be used.

Scientists have also collected evidence for evolution by observing and experimenting. The evidence for evolution is grouped into six categories: directly visible small-scale changes, biogeographic patterns, comparative anatomy, the fossil record, genetics, and classification. Each of these provides convincing evidence that the evolution of life has taken place.

Although many people have misconceptions about the theory of evolution it is an empirical fact. It is not just a theory; it is a potent collection of decades of observations and data that has been proven and tested. Scientists continue to collect and study new information to better understand the evolution of Earth's existence regardless of whether people believe in the theory of evolution or not. This information will help scientists to understand how to avoid future global catastrophes and also how to best use the resources on our planet. This information will also help us better serve the needs and wants of the people living on this planet.
