The Evolution Site

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

However the study of evolutionary theory is often controversial and the resultant misinformation can confuse people regarding its fundamentals. This Web site helps explain the most important concepts.

What is Evolution?

The current understanding of evolution focuses on the gradual, cumulative changes that occur within populations over time. These changes are the result of natural selection. This is a process that increases the number organisms with beneficial traits, which enable them to survive and reproduce in particular environments. This means that these organisms have more offspring than those that do not have the beneficial characteristics. This causes an alteration in genetics that could eventually lead to the creation of new species.

The term "evolution" is usually associated with "survival-of-the best" which implies that people who are more adjusted to certain conditions will have an advantage over those less well-adapted. However this is just one of many ways that evolution could occur.

Another popular way to use the word evolution is to suggest that species are able to move from one stage to the next. This kind of view can be referred to as anagenetic, or cladogenesis. This is not backed by the definition of evolution in science. The scientific theory of evolutionary changes focuses on the changes that occur in populations over time. These changes are the result of mutations that result from natural selection and genetic variation.

Charles Darwin was one of the scientists who supported this view. Alfred Russel Wallace who developed the macroevolution theory believed that this was the only way that higher forms of living could have evolved.

A theory must stand up to rigorous tests and evidence to be considered a theory. Evolution has stood the test of time, and has been supported in numerous scientific disciplines ranging from geology to biology the sciences of astronomy to chemistry. In fact evolution is regarded as one of the foundations of science today and is backed by the vast majority of scientists worldwide. Many people have misconceptions regarding the nature of the theory of evolution, especially how it relates with religion.

What is the Theory of Evolution (Evolutionary Theory)?

Evolution is an explanation in science of how living things change with time. It is based upon a few established facts: that more offspring are created than can survive and that different individuals have their physical traits and they are able to pass on traits to future generations. These observations are supported by a growing body of evidence derived from molecular biology, palaeontology and climatology functional morphology geology.

The theory of evolution based on natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to provide an explanation for why organisms are adapted to their biological and physical environment. 무료 에볼루션 is now the best-supported and widely-tested theory in the field of science. Its predictions have been proved out by the fact that, for example complex organisms are more likely to have fewer genetic mutations than simpler ones. The more successful an organism becomes in terms of surviving and reproducing the more likely it will transmit its genes to future generations.

Some people are against evolution because they think it suggests that there is no purpose to 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 skilled evolutionary biologists have been involved in developing and testing the theory of evolution, including several revered evangelical Christian leaders. Many of these researchers contributed to the understanding a vast array of phenomena, such as genomics and phylogenetics and also the formation and function fossils.

The word "theory" is sometimes used in a wrong sense to mean an assumption or speculation but in reality it is a scientific hypothesis that has been rigorously evaluated and refined over time. Scientists test hypotheses through repeating the experiments or observations that led them to their conclusions. So, the theory of evolutionary theory has been repeatedly proven, as have the corresponding theories of Copernican theory, atomic theory, and germ theory.

What is the Process of Evolution?

The process of evolution is the gradual change over time in the proportion of genetically distinct individuals within a particular species. This is the result of natural selection of individuals who are more adapted to their environment. The people who are more adaptable have higher chances of reproducing and survival. As more people survive and reproduce their genes are more widely distributed in the population. This is sometimes referred to as "survival of the strongest."

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

Over time, these shifts in the frequencies of alleles can lead to the formation of new species. The new species can then grow and evolve into newer forms. This process is called macroevolution. The development of new species is typically a result of changes in the environment, which makes certain resources available or creates new environmental challenges. For instance, the rise of finches in the Galapagos Islands is a result of the abundance of food sources and the need to defend themselves from predators.

In a larger sense it is possible to define evolution as any change in the character of living organisms over time. The change could be small, such as the development of a new coloration, or massive, for instance, the formation of a new organ.

Scientists who accept the theory of evolution generally agree on the importance of genetic change in the process that causes evolution. They also believe that evolution is a process that occurs in time, typically over a period of millions of years. However, they differ over the importance of different factors in accelerating or retarding the process, including the influence of environmental pressures sexual selection, and mutation bias. Despite these differences most scientists are still convinced that evolution is real and the evidence to prove it is overwhelming.

What is the Evidence of Evolution?

Since Darwin's time, scientists have gathered evidence that supports Darwin's theory of evolution. The evidence comes from fossils that show the evolution of organisms over time. Another evidence comes from the similarities between living organisms embryology, biogeography, genetics and comparative anatomy.

The evolutionary tree is the best way to prove evolution. It shows how different species are closely related. Another way to prove it is homologous structures, which have 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 evidence of evolution. For instance, arctic-foxes and ptarmigans grow white fur coats that blend into snow and ice. This is a type of convergent evolutionary process which suggests that the species have shared ancestors.

The vestiges of structures are another source of evidence. They are the remains of an organism which may have served some purpose in the distant past. The human appendix, for instance, is a vestige from an organ that was used to digest food. These structures tend to shrink in size as they're no longer in use which is a process referred to as natural selection.

Scientists have also gathered evidence for evolution by observing and testing. The evidence for evolution can be classified into six distinct categories: changes that can be observed at small scales, biogeographic distributions, comparative anatomy fossil records, genetics. Each of these categories offers 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 speculative theory, but a significant collection that is based on years of observation. Scientists continue to gather and analyze new data to better understand the arc of Earth's existence regardless of whether people believe in the theory of evolution or not. This information will help scientists to better understand how to avoid future global catastrophes, and how best to make use of the resources available on our planet. This information will also help us better serve the needs and wants of the people living on this planet.
