The Evolution KR Site

The theory of evolution through natural selection is the defining force of modern biology. It brings together disciplines like microbiology, palaeontology, and genetics.

The study of evolution may be controversial and the misinformation that is generated can lead to confusion about the fundamentals of evolution. This site explains the fundamental concepts.

What is Evolution?

Modern evolutionary theory is based on the gradual and cumulative changes that take place in populations over time. These changes are a result of natural selection, a process that increases the number of organisms that possess beneficial traits that enable them to live and reproduce in a particular environment. As a result, these organisms leave more offspring than those who don’t have these beneficial characteristics. This can lead to a genetic mutation that may eventually lead to new species.

The term “evolution” is usually associated with “survival-of-the fittest” which implies that individuals who are more adjusted to certain conditions will have an advantage over those who are less well-adapted. This is just one of many ways in which evolution can happen.

Another way to use the term “evolution” is to suggest that species are able to move from one stage to the next. This view of evolution can be referred to as anagenetic or cladogenesis. The definition of evolution that scientists have developed is not in agreement with this view. Instead, the scientific theory of evolution concentrates on the changes that occur within populations over time, and these changes are caused by genetic mutations and natural selection.

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

For a concept to be referred to as a theory, it must be able to stand up to rigorous testing and evidence. Evolution has stood the test of time, and has been backed by many scientific disciplines, from geology to biology, the sciences of astronomy to chemistry. In actual fact evolution is regarded as one of the fundamental tenets 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, and particularly how it relates to religion.

What is the Theory of Evolution?

Evolution is a scientific explanation of the way living things change over time. It is based on a variety of well-established observations: that more offspring are created than are likely to survive; that individuals differ from each other in their physical characteristics (phenotype) and that various traits confer varying rates of reproduction and survival; and that traits can be passed on to future generations. These observations are supported by a growing body of evidence from molecular biology, palaeontology and climatology functional geology and morphology.

The theory of evolution based on natural selection was initially conceived by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain why organisms are adapted to their biological and physical environments. It is currently the most well-supported and widely-tested theory in all of science. Its predictions were proven by the evidence that for instance, more complex organisms have fewer genetic mutations. Additionally the more efficient an organism is in reproduction and survival in its ability to reproduce, the more likely it will be to pass its genes to future generations.

Some people object to evolution based on the belief that it implies that there is no purpose to life. Many scientists who are religious, like the Cambridge palaeontologist Simon Conway Morris (BioLogos, 2014) believe that evolution is compatible with faith in God and can even be enhanced by it.

Many highly skilled evolutionary biologists have been involved in the development and testing the theory of evolution, which includes several revered evangelical Christian leaders. Many of these scientists have contributed to the understanding of a wide variety of phenomena, such as phylogenetics, genomics and the formation and role of fossils.

The term “theory” is sometimes used in a wrong sense to mean a guess or speculation but in reality it refers to a scientific idea that has been rigorously tested and refined over time. Scientists test their hypotheses by repeating experiments or observations that led to them. Thus, the theory of evolution has been repeatedly tested out, as have the related theories of Copernican, atomic and germ theory.

What is the Process of Evolution?

The process of evolution is a gradual shift in the genetically different 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 more adapted individuals have higher chances of reproducing and survival. As more of these individuals survive and reproduce their genes become more common within the population. This process is sometimes called “survival for the fittest.”

According to the theory of evolution, the mutations that produce genomic variation are the primary basis for evolutionary change. These mutations may occur randomly or under the influence of the environment. If mutations are random, the frequencies of the resulting alleles may differ from generation to generation. If a mutation is beneficial it can increase the frequency of the allele, causing the allele to be spread across the population.

Over time, 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 process is known as macroevolution. The development of a new species is usually caused by changes in the environment that make certain kinds of resources available or create new environmental challenges. For instance, the development of finches in the Galapagos Islands is a result of the availability of different food sources and the need defend themselves from predators.

In a larger sense the term “evolution” refers to any change that takes place in the traits of organisms over time. The change could be minor, such as the development of a new coloration, or large, such as the creation of a new organ.

Scientists who accept the theory of evolution generally recognize the importance of genetic change in generating evolution. They also acknowledge that the process of evolution takes place over a long time, often millions of years. However, they differ over the role of different factors that speed up or slow down this process, such as the influence 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 back his theory of evolution. This evidence is gathered from fossils which show the evolution of living organisms over time. Similarities between living and non-living organisms as well as embryology, biogeography and genetics are further evidence.

The evolutionary tree is the most effective method of proving evolution. It shows how different species are closely related. Homologous structures are another source of evidence. They have a similar structure but serve different purposes in different species, for instance, the wing of a bat or bird. Evolution is evident in the way that various species adapt and evolve to similar environments. For instance, arctic-foxes and Ptarmigans sport white fur coats that blend in with the snow and ice. This is a form of convergent evolutionary process which suggests that the species have shared ancestors.

The vestiges of structures are another source of evidence. They are the remains of an organism which may have served some purpose in the past. For instance, the human appendix is remnants of an earlier organ that was used to digest food. Natural selection causes these structures to shrink as they are no longer used.

Scientists have also gathered other evidence for evolution through observation and experimentation. The evidence for evolution can be grouped into six categories: directly observable small-scale changes in biogeographic distribution, comparative anatomy, the fossil record, classification and genetics. Each of these provides compelling evidence that the evolution of life took place.

Many people have misconceptions regarding the theory of evolution. But, it’s a fact. It isn’t simply a flimsy theory. It is a mighty collection of decades of research and observation that has been proven and tested. No matter what people believe or disbelieve about the theory of evolution scientists continue to study and collect new data in order to further comprehend the evolution of life on Earth. This knowledge will allow scientists to better understand how we can avoid future global catastrophes and how best to make use of the resources of our planet. This will allow us to better meet the needs of all the people living on the planet.
