The Evolution Site
The theory of evolution based on natural selection is the defining force of modern biology. It connects disciplines such as genetics, palaeontology and microbiology.
However the study of evolution is often controversial and the resulting misinformation can confuse people regarding its basic concepts. This site clarifies the most fundamental concepts.
What is Evolution?
Modern evolutionary theory is based on the gradual and cumulative changes that occur in populations over time. These changes are the result of natural selection, a process that increases the amount of organisms that have beneficial traits that enable them to live and reproduce in a specific environment. This means that these organisms leave more offspring than those that don't possess the beneficial characteristics. This causes an alteration in genetics that could eventually lead to the creation of new species.
The term "evolution" is frequently associated with the idea of "survival of the strongest," which means that individuals who are best adapted to a particular environment will be more successful than those who are not well-adapted. This is just one of many ways in which evolution can occur.
Another way that the word evolution is used is to suggest that a species will inevitably progress from one state to the next state of being. This view of evolution is referred to as anagenetic or cladogenesis. This theory is not supported by the scientific definition of evolution. Instead, the theory of evolution that is scientifically based focuses on changes that happen in populations over time and these changes are caused by genetic mutations and natural selection.
Certain scientists, including the great Charles Darwin, advocated this theory of evolution. Others, notably Alfred Russel Wallace, who came up with the macroevolution theory, believed that this was the only way that the higher forms of life could be derived from lower ones.

Evolution has stood the test of time, and has been supported in countless scientific disciplines from biology to geology, from astronomy to chemistry. Evolution is a fundamental concept in science and is believed by the majority of scientists across the globe. Many people are misinformed about the nature of evolution theory and how it connects with religion.
What is the Theory of Evolution (Evolutionary Theory)?
Evolution is the scientific explanation of the way living things change over time. It relies on a number of well-established observable facts such as the fact that more offspring are produced than could possibly survive in the long run; that individuals differ from one another in their physical characteristics (phenotype) and that distinct traits confer varying rates of survival and reproduction; and that traits can be passed on to the next generation. These observations are supported by the increasing body of evidence from molecular biology, palaeontology, functional morphology, climatology, and geology.
The theory of evolution by natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to provide an explanation for 에볼루션 사이트 (
Honeycutt-Pope-3.Blogbright.Net) why organisms are adapted to their physical and biological environment. It is today the most supported and most extensively tested theory in all of science. Its predictions were proved by the fact, for example that more complex organisms have fewer genetic mutations. In addition, the more successful an organism is at being able to reproduce and survive, the more likely it will be to pass on its genes to future generations.
Some people oppose evolution because they believe it implies that there is no purpose to life. However, a lot of scientists who are also religious believers such as the renowned Cambridge Palaeontologist Simon Conway Morris,
에볼루션사이트 believe that evolution is not only compatible with faith in God but can be enhanced by it (BioLogos 2014).
Many highly qualified evolutionary biologists have been involved in developing and testing the theory of evolution, including some respected evangelical Christian leaders. Many of them have contributed to the understanding of a broad variety of phenomena, like phylogenetics, genomics and the formation and purpose of fossils.
The term "theory" which is often misused refers to scientific hypotheses that have been tested and refined over a long period of time. Scientists test their theories by repeating experiments or observations that have led to them. Thus the theory of evolution 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 particular species. This change is a result of natural selection, which favors those who are better adapted to their environment. The individuals who are more adapted have higher chances of reproduction and survival. As more people survive and reproduce, their genes become more prevalent within the population. This process is sometimes referred to as "survival for the strongest."
According to evolution theory, mutations that lead to genomic variation are what triggers evolutionary change. These mutations can occur at random, or under the influence of the environment. When mutations occur at random and the frequencies of alleles will vary from generation to generation. When a mutation is beneficial it will increase the frequency of alleles which causes the allele to spread throughout the population.
Over time, these changes in allele frequencies could lead to the formation of new species. The new species can then grow and evolve into newer forms. This process is known as macroevolution. The creation of an entirely new species is typically due to changes in the environment which make certain kinds of resources available or create new environmental problems. For instance, the rise of finches in the Galapagos Islands is a result of the abundance of foods and the need to protect themselves from predators.
In a larger sense, evolution is defined as any change that takes place in the nature of living organisms over time. The change could be small or even the creation of a new coloration,

Scientists who believe in the theory of evolution generally agree on the importance of genetic change in generating evolution. They also acknowledge that the process of evolution takes place over a long time, typically millions of years. However, they differ on the role of different factors that speed up or slow down the process, including the impact of environmental pressures, sexual selection, and mutation bias. Despite these differences, the majority of scientists believe that evolution is happening and that evidence for this is overwhelming.
What is the Evidence of Evolution?
Since Darwin's time scientists have collected evidence to support his theory of evolution. Some of this evidence comes from fossils which reveal the changing traits of living organisms over time. Additional evidence can be found in the similarities between living organisms embryology, biogeography genetics and comparative anatomy.
The primary evidence of evolution can be found in the evolutionary tree, which illustrates how different species are connected. Homologous structures are another evidence. They share a common structure but perform different functions in different species, like the wings of a bird or bat.
