The Evolution Site

The theory of evolution based on natural selection is the defining force of modern biology. It connects disciplines such as genetics, microbiology, and Palaeontology.

However, the study of evolution is often controversial and the resulting misinformation can confuse people about its fundamentals. This site explains the fundamental concepts.

What is Evolution?

The current conception of evolution focuses on the gradual change that occurs within populations over time. These changes are the results of natural selection. This is a process that increases the number organisms with beneficial traits, which enable them to live and reproduce in particular environments. The organisms that have these traits produce more offspring because of the positive traits. This results in a genetic change that can eventually lead to the development of new species.

The term "evolution" is often associated with "survival-of-the best" which means that those who are more adaptable to specific environmental conditions will have an advantage over those less well adapted. In reality, this is only one of the many ways in which evolution can occur.

Another way of using the term "evolution" is to suggest that a species are able to move from one stage to the next. This view of evolution can be referred to as anagenetic, 에볼루션 카지노 or cladogenesis. This theory is not supported 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 produce natural selection and genetic variation.

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

A concept must be able stand against 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, from astronomy to chemistry. In reality evolution is regarded as one of the foundations of science today and is supported by the majority of scientists around the world. Many people are misinformed about the nature of the evolution theory, especially how it relates with religion.

What is the Theory of Evolution?

Evolution is the scientific explanation for how living things change over time. It is based on a few well-established facts: that many more offspring are born than can be surviving, that individuals differ in their physical traits and they can transmit traits to future generations. These observations are backed by the increasing amount of evidence from molecular biology, palaeontology, climatology, functional morphology and geology.

The theory of evolution through natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the late 19th century to provide an explanation for how organisms adapt 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. The more successful an organism becomes in terms of surviving and reproducing, the more likely it is to pass its genes on to future generations.

Some people oppose evolution because they think it implies there is no purpose to life. However, many scientists who are also religious believers like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution isn't just compatible with faith in God but is enhanced by it (BioLogos 2014).

In fact, a large number of highly trained evolutionary biologists, including some who are respected 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 wide variety of phenomena such as phylogenetics, genomics, and the development and function of fossils.

The word "theory", which is often used incorrectly refers to scientific hypotheses that have been tested and refined over time. Scientists test hypotheses through repeating the experiments or observations that led them to them. The theory of evolution has been repeatedly tested out, as have the related theories of Copernican, germ and atomic theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the genetically different individuals within a particular species over time. This is the result of natural selection, which favors those who are better adapted for their environment. The more adapted individuals have higher chances of reproduction and survival. As more individuals survive and reproduce, their genes are more common in the population. This is sometimes referred to as "survival of the strongest."

According to the theory of evolution, the mutations that produce genetic variation are the basic material of evolutionary change. These mutations could occur at random or under the influence of the environment. When mutations are random, the frequency of the resultant alleles could vary from generation to generation. In contrast, when an alteration is beneficial, it increases the frequency of the allele, causing it to spread throughout the population.

As time passes, these changes in allele frequencies can lead to the formation of new species. The new species may continue to evolve and become newer forms. This is known as macroevolution. The formation of new species is usually a result of changes in the environment, which make certain resources available or creates new environmental problems. The development 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 broader context, evolution can be defined as any change in the characteristics of living organisms over time. The change could be subtle, such as the development of a new color or a dramatic change, such as the formation of an organ.

Scientists who believe in the theory of evolution generally believe that genetic change is important in generating evolution. They also acknowledge that evolution is a process that happens over time, typically over a period of millions of years. They differ on the importance of various factors that may speed up or slow down this process. For example the role of sexual selection, environmental pressures, and mutation bias. Despite these differences scientists believe that evolution has happened and the evidence to prove 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. This evidence is gathered from fossils that demonstrate the evolution of organisms over time. Other evidence is found in similarities between living organisms, embryology, biogeography, genetics and comparative anatomy.

The most important proof of evolution is in the evolutionary tree, which shows how different species are related. Homologous structures are another evidence. They share a similar structure but serve different purposes in different species, for instance, the wings of a bird or bat. Evolution is evident in the way that different species adapt and develop to similar environments. For instance, arctic foxes and ptarmigans have seasonal white pelts to blend into snow and ice. This is a form of convergent evolutionary process, which suggests that the species share common ancestors.

Another piece 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 바카라 사이트 무료에볼루션 바카라 체험 (http://118.25.96.118) example is a remnant of 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 gathered evidence for evolution through observation and experimenting. The evidence for evolution can be divided into six categories: directly visible small-scale changes, biogeographic distribution and comparative anatomy, the fossil record, classification and genetics. Each of these provides compelling evidence that evolution of life took place.

Although many people have misconceptions about the theory of evolution, it is an established fact. It is not simply a flimsy theory. It is a mighty collection of decades of observations and data that has been tested and proven. Regardless of what people believe or disbelieve about the theory of evolution scientists continue to study and gather new information in order to further know the story of life on Earth. This information will help scientists to better understand how to avoid future global catastrophes and how best to make use of the resources on our planet. This information will also allow us to better meet the needs and desires of the people living on our planet.
