The Evolution Site

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

The study of evolution can be controversial, and the misinformation that is generated can lead to confusion over the fundamentals of evolution. This site clarifies essential 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 the result of natural selection, a process that increases the number of organisms who have traits that are beneficial and allow them to survive and reproduce in a specific environment. They produce more offspring as a result of the positive traits. This leads to a genetic change 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 better adapted to certain environmental conditions will have a distinct advantage over those who are less well-adapted. This is only one of the many ways in which evolution can occur.

Another popular way to use the word evolution is to suggest that a species will progress from one state to the next. This view of evolution is referred to as anagenetic or cladogenesis. The definition of evolution that scientists have developed does not support this idea. Instead the theory of evolution that is scientifically based concentrates on the changes that happen in populations over time and these changes are caused by genetic mutations and natural selection.

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

A theory must stand up to rigorous tests and evidence to be considered as a theory. Evolution has stood the test of time, and has been backed by countless scientific disciplines from geology to biology, chemistry to astronomy. Evolution is a cornerstone of science and is supported by the majority of scientists across the world. Many people are misinformed about the nature of the evolution theory particularly how it is connected with religion.

What is the Theory of Evolution?

Evolution is the scientific explanation of the way living things change over time. It is based on a range of well-established and observable facts: that more offspring are produced than can possibly survive in the long run; that individuals differ from each other in their physical characteristics (phenotype) and that various characteristics result in different rates of reproduction and 에볼루션 무료 바카라 에볼루션 룰렛 (www.Bitsdujour.com) survival; and that traits can be passed on to the next generation. These findings are backed by an increasing body of evidence 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 way to explain how organisms are able to adapt to their physical and biologic environments. It is the most widely accepted and validated theory in science. Its predictions have been proved out by the fact that, for example more complex organisms have less genetic mutations than simpler ones. In addition the more efficient an organism is in surviving and reproducing in its ability to reproduce, the more likely it will be to pass on its genes to the next generation.

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

Many highly qualified evolutionary biologists have been involved in the development and testing the theory of evolution, including several highly respected evangelical Christian leaders. Many of these researchers contributed to the understanding a broad range of phenomena, including genomics and 에볼루션 카지노 사이트 phylogenetics, as well as the formation and function of fossils.

The word "theory", which is often misused refers to scientific hypothesis that has been tested and refined over a period of time. Scientists test their hypotheses by repeating experiments or observations that resulted in them. Thus, the theory of evolution has been repeatedly tested out, as have the related theories of Copernican, germ theory, and atomic 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 specific species. This change is the result of natural selection of those who are more adapted to their environment. The more adapted individuals have better chances of reproduction and survival. As more of these individuals survive and reproduce, their genes become more common in the general population. This is sometimes described as "survival of the fittest."

According to the theory of evolution the causes of mutations that result in genomic variation are what triggers evolutionary change. These mutations may occur randomly or be influenced by the environment. If mutations occur in a random manner and the frequencies of alleles can vary from generation-to-generation. If a mutation is beneficial it will increase the allele frequency, causing the allele to spread throughout the population.

As time passes, these changes in allele frequencies could lead to the formation of new species. The new species can then continue to evolve and become newer forms. This is a process called macroevolution. The formation of a new species is usually due to changes in the environment that allow certain kinds of resources to become available or cause new environmental problems. For example, the evolution of finches on the Galapagos Islands is a result of the availability of various food sources and the need protect themselves from predators.

In a wider context it is any change that takes place in the nature of organisms over time. The change could be small or even the creation of a new coloration or large, 에볼루션바카라사이트 such as the formation of a new organ.

Scientists who accept evolution theory generally believe that genetic change is essential in the process of generating evolution. They also believe that evolution is a process that occurs over time, usually over millions of years. They differ on the importance of different 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 evidence for this is overwhelming.

What evidence can be found for evolution?

Throughout the years since Darwin's time, scientists have collected evidence to support his theory of evolution. This evidence is gathered from fossils which show the evolution of organisms over time. Additional evidence can be found in the similarities between living organisms, embryology, 에볼루션바카라 biogeography, genetics and comparative anatomy.

The evolutionary tree is the best method to prove the existence of evolution. It demonstrates how species are closely related. Homologous structures are another proof. They share a similar structure, but they perform different functions in different species, for instance, the wings of a bird or bat. The fact that different species develop and adapt to the same environment is another sign of evolution. For example, arctic foxes and ptarmigans grow seasonal white pelts to blend in with snow and ice. This is a kind of convergent evolution, which suggests that the species had common ancestors.

The vestiges of structures are another source of evidence. These are a part of an organism that may have served some purpose in the past. For example the human appendix is remnants of an earlier organ used to digest food. These structures tend to shrink in size once they are no longer used which is a process referred to as natural selection.

Scientists have also collected other evidence of evolution through observation and experimentation. The evidence for evolution can be divided into six distinct categories: directly observed changes at a smaller scale biogeographic distributions, comparative anatomy fossil records, genetics. Each of these categories provides convincing evidence for the evolution of life.

Many people are misinformed about the theory of evolution. However, it is an actual fact. It is not a theory but a significant collection that is founded on decades of observation. No matter what people believe or don't believe about the theory of evolution scientists continue to study and discover new information in order to further know the story of life on Earth. This information will aid scientists better understand how to prevent future global catastrophes and also how to best use our planet's resources. This information will also allow us to better meet the needs and wants of all the people living on our planet.
