The Evolution Site

The theory of evolution by natural selection is the defining force of modern biology. It connects disciplines like microbiology, palaeontology, and genetics.

The study of evolution may be controversial, and the misinformation that comes from it can cause confusion about its basic concepts. This Web site helps explain the most important concepts.

What is Evolution?

The current understanding of evolution is based on the gradual, cumulative changes that occur within populations over time. These changes are the result of natural selection, which increases the number of organisms that possess beneficial traits that enable them to live and reproduce in a particular environment. These organisms produce more offspring because of the beneficial traits. This could cause a genetic change that could eventually lead to the creation of new species.

The term "evolution" is often associated with "survival-of-the most fittest" which implies that people who are more adapted to certain environmental conditions will have an advantage over those who are less well-adapted. In actuality it is only one of many ways in which evolution can occur.

Another way to use the term "evolution" is to suggest that a species will progress from one state to the next. This view of evolution can be described as anagenetic or cladogenesis. The definition of evolution in science does not support this idea. Instead, the theory of evolution that is scientifically based is based on the changes that happen within 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 this was only way the higher living forms could have evolved.

A concept must be able stand up to rigorous tests and evidence to be considered as a theory. Evolution has stood the test of time and has been supported in many scientific disciplines, from geology to biology, chemistry to astronomy. Evolution is a cornerstone of science and 무료에볼루션 is supported by the majority of scientists around the world. Many people are misinformed about the nature of evolution theory particularly how it is connected with 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 a few known facts: that more offspring are born than can survive, that individuals differ in their physical characteristics, and that they can pass on traits to future generations. These findings are backed by a growing body of evidence from molecular biology, palaeontology climatology functional geology, morphology.

The theory of evolution based on natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain why organisms are adapted to their physical and biological environment. It is today the most supported and widely-tested theory in the field of science. Its predictions were confirmed by the fact that for instance, more complex organisms have less genetic mutations. Additionally the more efficient an organism is in surviving and reproducing and reproducing, the more likely it will be to pass on its genes to the next generation.

Some people object to evolution because they believe it implies that there is no reason to life. However, many scientists who are also religious believers such as the renowned Cambridge Palaeontologist Simon Conway Morris, believe that evolution is not just compatible with faith in God but also enhances it (BioLogos 2014).

In reality, a large number of highly qualified evolutionary biologists, including some who are renowned evangelical Christian leaders have been involved in the creation and testing of the theory of evolution. Many of these scientists have contributed to the understanding of a vast variety of phenomena such as phylogenetics, genomics, 에볼루션 블랙잭 and the formation and function of fossils.

The word "theory" is often used in a wrong sense to mean an assumption or speculation however it actually refers to a scientific idea that has been systematically tested and refined over time. Scientists test hypotheses by repeating the experiments or 무료 에볼루션 코리아 (imoodle.win) observations that led them to the conclusion. The theory of evolution has been repeatedly borne out as have the corresponding theories of Copernican, germ and atomic theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the proportions of genetically diverse 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 more adapted individuals have a greater chance of survival and reproduction. As more people survive and reproduce, their genes are more widely distributed within the population. This process is sometimes called "survival for the strongest."

According to the theory of evolution the mutations that cause genomic variation are the raw material for evolution. These mutations could occur randomly or be affected by the environment. When mutations are random, the frequency of the resultant alleles could differ from generation to generation. However, when an alteration is beneficial it will increase the frequency of the allele, which causes it to spread throughout the population.

The changes in frequency of alleles could lead to new species over time. The new species will then grow and evolve into new forms. This is known as macroevolution. The development of an entirely new species is typically caused by changes in the environment which make certain kinds of resources available or create new environmental challenges. For instance, the development of finches on the Galapagos Islands is a result of the availability of various foods and the need to defend themselves from predators.

In a broader sense the term "evolution" refers to any change that occurs in the characteristics of organisms over time. This change can be small, such as the development of a new coloration or massive, for instance, the development of a brand new organ.

Scientists who believe in the theory of evolution generally agree that genetic change is crucial in the process of generating evolution. They also agree that the process of evolution happens over a long time, typically millions of years. However, they differ on the role of various factors in speeding or slowing the process, including the role of environmental pressures, sexual selection and mutation bias. Despite these differences scientists believe that evolution has happened and that evidence for this is overwhelming.

What is the evidence for evolution?

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

The evolutionary tree is the most effective method of proving evolution. It shows how species are related. Another evidence source is homologous structures, 무료에볼루션 which share a similar structure in different species but have distinct functions like the wings of birds and bats. The fact that different species develop and adapt to the same environment is also a sign of evolution. For example, arctic-foxes and Ptarmigans have white seasonal pelts which blend with snow and ice. This is a kind of convergent evolution that suggests that the species has common ancestors.

Vestigial structures are another piece of evidence. They are the remains of an organism that may have served a purpose in the distant past. The human appendix, for instance is an odour from an organ that was used to digest food. Natural selection is a process that causes the structures to shrink when they cease to be used.

Scientists have also gathered evidence for evolution through observation and testing. The evidence for evolution is divided into six categories: 에볼루션 사이트 directly observable small-scale changes, biogeographic distribution as well as comparative anatomy, 무료에볼루션 fossil record, classification and genetics. Each of these provides compelling evidence that the evolution of life took place.

While many people are misinformed about the theory of evolution, it is an empirical fact. It is not simply a flimsy theory. It is a powerful collection of decades of research and observation that has been proven and tested. No matter what people believe or deny about the theory of evolution scientists continue to research and discover new information to better comprehend the evolution of life on Earth. This information will aid scientists better understand how to prevent future global catastrophes and also how to best utilize the resources on our planet. It will also enable us to better serve the needs of all the people on this planet.
