The Evolution Site
The theory of evolution by natural selection is the unifying force of modern biology. It brings together disciplines such as microbiology, palaeontology, genetics and palaeontology.
However the study of evolutionary theory is often controversial, and the resulting misinformation can confuse people about the fundamentals of evolution. This site clarifies essential concepts.
What is Evolution?
The modern understanding of evolution is based on the gradual and cumulative changes that happen within populations over time. These changes are the result of natural selection. This is a process which increases the number of organisms with beneficial traits, which enable them to survive and reproduce in particular environments. They produce more offspring because of the beneficial characteristics. This results in a genetic change that can 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 better adaptable to specific environmental conditions will have an advantage over those who are less well-adapted. However this is just one of the many ways in which evolution can occur.
Another way that the word evolution is used to suggest that a species will eventually move from one state to the next state of being. This type of view of evolution is called anagenetic or cladogenesis. This is not backed by the definition of evolution in science. The theory of evolution that is based on science change focuses instead on the changes that occur in populations over time. These changes are caused by mutations that result from natural selection and genomic variation.
Some scientists, including the great Charles Darwin, advocated this theory of evolution. Others, including Alfred Russel Wallace, who created the macroevolution theory believed that this was the only way the higher forms of life could be derived from lower forms.
For a concept to be referred to as a theory, it has to be able to stand up to rigorous testing and evidence. The evidence of evolution has stood up to the test of time and has been backed by a myriad of studies across a wide range of sciences, from biology to geology, chemistry to astronomy. In actual fact evolution is considered to be one of the foundations of science today and is backed by the vast majority of scientists around the world. However, many people have misconceptions about the theory of evolution, specifically how it relates to religion.
What is the Theory of Evolution?
Evolution is the scientific explanation for the way living things change over time. It is based upon a few known facts: that more offspring are born than can be surviving, that individuals differ in their physical characteristics, and that they can transmit traits to the next generation. These findings are supported by the increasing amount of evidence from molecular biology, palaeontology, functional morphology, climatology, and geology.
The theory of evolution through natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the mid-19th century to explain the reason that organisms are adapted to their biological and physical environment. It is now the best-supported and widely-tested theory in all of science. Its predictions were confirmed by the fact that for instance, more complex organisms are less susceptible to genetic mutations. In addition, the more successful an organism is in reproduction and survival and reproducing, the more likely it will be to pass its genes to future generations.
Some people object to evolution because they believe that it implies that there is no purpose to life. Many scientists who are religious believers, like 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, which includes several highly respected evangelical Christian leaders. Many of these researchers contributed to the understanding of a wide range phenomena, including genomics and phylogenetics, and also the formation and function fossils.
The term "theory" that is often misinterpreted is a reference to a scientific hypothesis that has been tested and refined over a long period of time. Scientists test hypotheses through repeating the experiments or observations that led them to the conclusion. Thus, the theory of evolutionary theory has been repeatedly proven, along with the related theories of Copernican theory, atomic theory, and germ theory.
What is the Process of Evolution?
The process of evolution is the gradual shift over time in the proportion of genetically distinct individuals within a specific species. This change is a result of natural selection of individuals that are more well-adapted to their environment. The individuals who are more adapted have better chances of reproduction and survival. As more of these individuals survive and reproduce their genes are more prevalent within the population. This is sometimes referred to as "survival for the strongest."
According to the theory of evolution the mutations that result in genetic variation are the basic material of evolutionary change. These mutations could occur at random or be affected by the environment. If mutations occur in a random manner, the allele frequencies may vary from generation to generation. When a mutation is beneficial, it increases the frequency of the allele, causing it to spread throughout the population.
As time passes, these changes in the frequencies of alleles can lead to the formation of new species. The new species will evolve and develop into newer forms. This is known as macroevolution. The formation of a new species is often due to changes in the environment which provide certain types of resources available or cause new environmental problems. The development of finches in the Galapagos Islands, for example, is due to the availability of fresh food and the need to defend themselves against predators.
In a wider sense, evolution can be defined as any change in the character of living organisms over time. This change can be subtle, such as the development of a new color or dramatic, like the formation of an organ.
Scientists who accept the theory of evolution generally recognize the importance of genetic change in generating evolution. They also agree that evolution is a process that takes place in time, typically over millions of years. However, they differ on the role of various factors that speed up or slow down the process, including the impact of environmental pressures, sexual selection and mutation bias. Despite these differences scientists believe that evolution has occurred and that the evidence for this is overwhelming.

Since Darwin's time, scientists have collected evidence to back his theory of evolution. Some of this evidence comes from fossils, which demonstrate the changing features of living things over time. Similarities between living and non-living organisms as well as embryology, biogeography and genetics are also evidence.
The most important proof of evolution is in the evolutionary tree, which demonstrates how species are related. Another source of evidence is homologous structures, which have similar structure in different species but have distinct functions, such as the wings of birds and bats. The fact that different species evolve and adapt to a similar environment is also a sign of evolution. For example, arctic foxes and ptarmigans grow seasonal white pelts to blend in with snow and ice. This is a form of convergent evolution that suggests that the species has common ancestors.
Another source of evidence is vestigial structures, which are unused parts of an organism that may have served a purpose in the distant ancestors. The human appendix, for example is a remnant of an organ that was used to digest food. These structures tend to shrink in size once they are no longer used in a process called natural selection.
Scientists have also gathered other evidence of evolution through observation and experimentation. The evidence for evolution can be grouped into six categories: directly observed small-scale changes, biogeographic distribution and comparative anatomy, the fossil record, genetics, and classification. Each of these categories offers solid evidence for the evolution of life.
Many people are misinformed about the theory of evolution. However, it's an actual fact. It is not a theory but rather a powerful collection based on decades of observation. Scientists continue to gather and analyze new data to better understand the history of the Earth's life, regardless of whether people believe in the theory of evolution or not. This information will aid scientists understand how to prevent future global catastrophes and how to best utilize the resources on our planet. This information will also allow us to better meet the needs and desires of the people who live on this planet.
