What Is Evolution Site And Why Is Everyone Speakin' About It

The Evolution Site

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

The study of evolution can be controversial and the misinformation that comes from it can lead to confusion over its fundamentals. This website helps to explain the most important concepts.

What is Evolution ?

The modern 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 which increases the number organisms with beneficial traits, which help them to survive and reproduce in specific environments. This means that these organisms produce more offspring than those that don't have these beneficial traits. This causes the genetic changes that can eventually lead to the creation of new species.

The term "evolution" is usually associated with "survival-of-the fittest" which implies that individuals who are more adaptable to specific environmental conditions will have a distinct advantage over those who are less well-adapted. However this is just one of the many ways in which evolution can occur.

Another popular way to use the term "evolution" is to suggest that a species can change from one state to the next. This view of evolution is called anagenetic or cladogenesis. The definition of evolution that scientists have developed does not support this idea. The theory of evolution that is based on science changes focuses on the changes that occur in populations over time. These changes are the result of mutations which result in natural selection and genetic variation.

Some scientists, such as the great Charles Darwin, advocated this theory of evolution. Others, including Alfred Russel Wallace, who developed the theory of macroevolution believed that this was the only way that the higher forms of life could have evolved from the lower ones.

A theory must stand up to rigorous tests and evidence to be considered as a theory. The evidence for evolution has stood the test of time and has been supported by countless studies in many scientific disciplines, ranging from biology to geology to chemistry to astronomy. Evolution is the foundation of science and is believed by the majority of scientists around the globe. However, there are many misconceptions about the nature of the theory of evolution, particularly the relationship it has with religion.

What is the Theory of Evolution (Evolutionary Theory)?

Evolution is the scientific explanation for how living things change over time. It is based on a range of well-established observable facts such as the fact that more offspring are often produced than can possibly survive and that individuals differ from each other in their physical characteristics (phenotype); that different traits have different rates of survival and reproduction and reproduction; and that these traits can be passed down to future generations. These observations are supported by a growing body of evidence from molecular biology, palaeontology climatology functional geology, morphology.

The theory of evolution through natural selection was developed independently by Charles Darwin and Alfred Russel Wallace in the late 19th century as an explanation for the reason that organisms are adapted to their physical and biological environments. It is today the most supported and most extensively tested theory in all of science. Its predictions have been borne out by the evidence that, for instance complex organisms have less genetic mutations than simpler ones. The more successful an organism becomes in terms of surviving and reproducing the more likely it is to pass its genes on to the next generation.

Some people are against evolution because they believe it suggests that there is no reason for existence. However, a lot of scientists who are also religious, such as the prominent Cambridge Palaeontologist Simon Conway Morris, believe that evolution isn't just compatible with belief in God but also enhances it (BioLogos 2014).

Many highly qualified evolutionary biologists have been involved in the development and testing the theory of evolution, which includes some respected evangelical Christian leaders. Many of these scientists have contributed to the understanding of a wide variety of phenomena, including phylogenetics and 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 time. Scientists test their theories by repeating the experiment or observations that resulted in them. So the theory of evolutionary theory has been repeatedly proven, as have the corresponding theories of Copernican theory as well as atomic theory and germ theory.

What is the Process of Evolution?

The process of evolution is a gradual change in the genetic makeup of diverse individuals within a species over time. This change is a result of natural selection, which favors those who are better adapted to their environment. The people who are more adaptable have better chances of reproduction and survival. As more of these people survive and reproduce, their genes are more prevalent in the population. This process is sometimes referred to as "survival for the strongest."

According to the theory of evolution, the mutations that produce genomic variation are the primary material of evolutionary change. These mutations may occur randomly or under the influence of the environment. If mutations occur in a random manner and the frequencies of alleles will vary from generation to generation. If a mutation is beneficial, it will increase the frequency of alleles and cause the allele to spread throughout the population.

These changes in allele frequency can lead to new species in the course of time. The new species will then develop and evolve into new forms. This is known as macroevolution. The development of new species is often caused by changes in the environment which makes 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 foods and the need to defend themselves against predators.


In a broader sense, evolution is defined as any change that takes place in the characteristics of organisms over time. This change can be subtle, like the development of new colors or dramatic, like the formation of an organ.

Scientists who believe in the theory of evolution generally agree that genetic changes are crucial in the process of the process of generating evolution. They also acknowledge that evolution is a process that occurs over time, typically over a period of millions of years. They differ in the importance of various factors that can accelerate or slow down this process. For example the role played by sexual selection, environmental pressures, and mutation bias. Despite these differences, the majority of scientists are still convinced that evolution is real and the evidence to prove it is overwhelming.

What evidence can be found for evolution?

Since Darwin's time scientists have collected evidence to back his theory of evolution. This evidence comes from fossils which show the evolution of living organisms over time. Another evidence comes from similarities among living organisms, embryology, biogeography, genetics and comparative anatomy.

The evolutionary tree is the most effective method to prove the existence of evolution. It shows how different species are related. Homologous structures are another proof. They share a common structure but perform different functions in different species, like the wing of a bat or bird. The fact that different species develop and adapt to the same environment is also a sign of evolution. For example, arctic foxes and ptarmigans develop seasonal white pelts to blend into snow and ice. This is a type of convergent evolutionary process, which suggests that the species share common ancestors.

Vestigial structures are another piece of evidence. These are a part of an organism that could serve a function in the past. For example, the human appendix is a vestige of a once-used organ used to digest food. These structures tend to shrink in size when they're no longer in use in a process called natural selection.

Scientists have also collected evidence for evolution through observation and experimenting. The evidence for evolution can be classified into six distinct categories: directly observed changes at a smaller scale biogeographic distributions, comparative anatomies fossil records and genetics. Each of these categories offers compelling evidence for the evolution of life.

Many people have misconceptions about the theory of evolution. However, it is an actual fact. It is not only a theory, it is a mighty collection of decades of observations and data that has been proven and tested. Scientists continue to collect and study new information to better understand the evolution of the Earth's life regardless of whether people believe in the theory of evolution or not. This information will allow scientists to better understand how we can avoid future catastrophes on the planet, and how to use the resources available on our planet. This information will also allow us to better serve the needs and wants of the people living on this planet.
