How To Tell If You're Prepared For Evolution Site

The Evolution Site

The concept of natural selection as the basis of evolution is the central force in modern biology. It ties together disciplines that are as diverse as genetics microbiology and the study of palaeontology.

The study of evolution may be controversial and the misinformation that is generated can lead to confusion over its basic concepts. This site can help explain the most important concepts.

What is Evolution?

Modern evolutionary theory focuses on the gradual and cumulative changes that occur in populations over time. These changes are caused by natural selection, which 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 who don't have these beneficial characteristics. This could result in a genetic mutation that may eventually lead to the creation of new species.

The term "evolution" is frequently associated with the idea of "survival of the fittest," which implies that those people who are the most adapted to a specific environment will have an advantage over those who aren't adapted to the environment. In reality it is only one of many ways in which evolution can occur.

Another popular way in which the term "evolution" is used is to suggest that a species will eventually move from one state of being to the next one. This kind of view can be described as anagenetic, or cladogenesis. This view is not supported by the definition of evolution that is scientifically accepted. Instead, the scientific theory of evolution focuses on changes that take place within populations over time, and these changes are caused by genetic mutations and natural selection.

Some scientists, including the great Charles Darwin, advocated this view of evolution. Alfred Russel Wallace who developed the macroevolution theory believed this was the only way in which the higher forms of living could have evolved.

For a concept to be called a theory, it has to be able to stand up to rigorous tests and evidence. Evolution has stood the test of time and has been backed by countless scientific disciplines from biology to geology, from astronomy to chemistry. In actual fact, evolution is accepted as one of the fundamental tenets of science today and is backed by the majority of scientists worldwide. However, there are many misconceptions about the theory of evolution, and particularly how it is related to religion.

What is the Theory of Evolution?

Evolution is the scientific explanation of the way living things change over time. It relies on a number of well-established and observable facts that show that more offspring are often produced than could possibly survive in the long run; that individuals differ from one another in their physical characteristics (phenotype); that different characteristics result in different rates of reproduction and survival; and that traits can be passed down to future generations. These findings are supported by the growing body of evidence from molecular biology, palaeontology climatology, functional morphology and geology.

Charles Darwin and Alfred Russel Wallace independently developed the theory of evolution through selection in the middle of the 19th century as a way to explain how organisms are adapted their biological and physical environments. It is today the most supported and most extensively tested theory in all of science. Its predictions were proven by the evidence that for instance, more complex organisms are less susceptible to genetic mutations. In addition, the more successful an organism is in reproduction and survival in its ability to reproduce, the more likely it will be to pass on its genes to future generations.

Some people object to evolution based on the belief that it implies that there is no reason 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 belief in God but is enhanced by it (BioLogos 2014).

In actual fact, a significant number of highly skilled evolutionary biologists, some of who are respected evangelical Christian leaders have been involved in the creation and testing of the theory of evolution. Many of these scientists contributed to the understanding a broad range of phenomena, including phylogenetics and genomics, as well as the formation and function of fossils.

our homepage "theory", which is often misinterpreted is a reference to a scientific hypotheses that have been tested and refined over a period of time. Scientists test hypotheses by repeating the experiments or observations that led them to the conclusion. Therefore, the theory of evolution has been repeatedly borne out and so have the theories of Copernican, germ and atomic theory.

What is the Process of Evolution?

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

According to evolution theory the causes of mutations that result in genomic variation are what drives evolution. These mutations could occur at random or be influenced by the environment. If mutations are random, the resulting allele frequencies may differ from generation to generation. When the mutation is beneficial it can increase the frequency of the allele, which causes it to spread through the population.

Changes in the frequency of alleles can result in new species over time. The new species will then grow and evolve into new forms. This process is known as macroevolution. The development of new species is usually a result of changes in the environment that make certain resources accessible or creates new environmental problems. For example, the evolution of finches in the Galapagos Islands is a result of the availability of different foods and the need to defend themselves from predators.


In a broader sense the term "evolution" refers to any change that occurs in the traits of living organisms over time. The change could be subtle, such as the development of a new color or dramatic, like the development of an organ.

Scientists who believe in evolution theory generally agree that genetic changes are crucial in the process of generating evolution. They also agree that evolution is a process that happens in time, typically over millions of years. They differ on the importance of various factors that can accelerate or slow down the process. For instance the role played by sexual selection, environmental pressures and mutation bias. Despite these disagreements, most scientists are still convinced that evolution is real and the evidence in support of this is overwhelming.

What is the Evidence of Evolution?

Since Darwin's time, scientists have gathered evidence to support his theory of evolution. Some of this evidence comes from fossils, which reveal the changing traits of living organisms over time. Similarities between living organisms as well as embryology, biogeography and genetics are also evidence.

The primary evidence of evolution is in the evolutionary tree, which shows how different species are related. Another evidence source is homologous structures, which have a similar structure in different species, but perform distinct functions like the wings of bats and birds. Evolution is evident in the way that various species adapt and evolve to similar environments. For instance, arctic foxes and Ptarmigans sport white seasonal pelts which blend with snow and ice. This is a form of convergent evolutionary, which suggests that the species had common ancestral ancestors.

Another evidence point is the existence of vestigial structures. These are unused parts of an organism which could have served a purpose in the distant ancestor. The human appendix for instance is an odour from an organ that once used to digest food. These structures tend to shrink in size as they are no longer utilized, a process known as natural selection.

Scientists have also gathered additional evidence of evolution via observation and experimentation. The evidence for evolution can be divided into six distinct categories: directly observed changes at a smaller scale, biogeographic distributions, comparative anatomy fossil records, genetics. Each of these categories provides compelling evidence for the evolution of life.

While many people are misinformed about the theory of evolution, it is an established fact. It is not just a theory; it is a powerful collection of decades of observation and accumulated data that has been tested and proven. Scientists continue to gather and study new information to better understand the history of Earth's existence regardless of whether or not people believe in the theory of evolution or not. This knowledge will allow scientists to better understand how to prevent future global catastrophes and how to best utilize the resources available on our planet. This information will also help us better meet the needs and wants of the people living on our planet.
