The Evolution Site
The theory of evolution by natural selection is the unifying force of modern biology. It ties together disciplines that are as diverse as genetics microbiology, and Palaeontology.
However the study of evolution is often controversial and the resulting misinformation can confuse people regarding its basic concepts. This site clarifies essential concepts.
What is Evolution?
The modern conception of evolution focuses on the gradual change that occurs within populations over time. These changes are the result of natural selection. This is a process which increases the number organisms with beneficial traits, which help them to survive and reproduce in particular environments. These organisms produce more offspring because of their positive traits. This could result in a genetic mutation that could eventually lead to the creation of new species.
The term "evolution", is often associated with "survival-of-the fittest" which means that those who are more adapted to certain environmental conditions will have a distinct advantage over those who are less well-adapted. However this is just one of many ways in which evolution can occur.
Another way to use the word evolution is to suggest that species are able to move from one stage to the next. This type of view of evolution could be described as anagenetic, or cladogenesis. The definition of evolution in science does not support this idea. Instead the scientific theory of evolution focuses on changes that take place in populations over time and these changes are caused by mutations that produce genomic variation and natural selection.
Some scientists, including the great Charles Darwin, advocated this view of evolution. Alfred Russel Wallace who developed the macroevolution theory believed that this was only way the higher living forms could have evolved.
A theory must stand up to rigorous tests and evidence in order to be considered a theory. The evidence for evolution has stood the test of time and has been supported by numerous studies in a wide range of sciences, from biology to geology to chemistry to astronomy. Evolution is a fundamental concept in science and is supported by a majority of scientists across the world. However, many people have misconceptions about the theory of evolution, particularly how it is related to religion.
What is the Theory of Evolution (Evolutionary Theory)?
Evolution is a scientific explanation of the way living things change over time. It is based on a variety of well-established observable facts: that more offspring are produced than could possibly survive; that individuals differ from each other in their physical characteristics (phenotype); that different traits confer varying rates of survival and reproduction; and that traits can be passed down to the next generation. These observations are supported by a growing body of evidence from molecular biology, palaeontology and climatology functional morphology geology.
The theory of evolution through natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain why organisms are adapted to their physical and biological environment. It is today the most supported and most widely tested theory in the field of science. Its predictions have been proved out by the fact that, for 에볼루션 바카라사이트 example, more complex organisms tend to have fewer genetic mutations than simpler ones. The more successful an organism becomes in terms of its longevity and reproducing the more likely it will transfer its genes to future generations.
Some people oppose evolution because they believe it implies that there is no reason to life. Many scientists who are religious like Cambridge palaeontologist Simon Conway Morris (BioLogos, 2014), believe that evolution is compatible with faith in God and even enhanced by it.
Many highly skilled evolutionary biologists have been involved in the development and testing the theory of evolution, including several revered evangelical Christian leaders. Many of these scientists have contributed to the understanding of a broad variety of phenomena like phylogenetics, genomics and the formation and purpose of fossils.
The word "theory" is often used in a wrong sense to mean a guess or speculation, when in fact it is a scientific hypothesis that has been systematically evaluated and refined over time. Scientists test their theories by repeating the experiments or observations that led to them. The theory of evolution has been repeatedly borne 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 proportions of genetically different individuals within a species over time. This is the result of natural selection, which favors those who are better adapted to their environment. The individuals who are more adaptable have a greater chance of survival and reproduction. As more of these individuals survive and 에볼루션 사이트 reproduce their genes are more prevalent in the general population. This process is sometimes called "survival for the fittest."
According to evolution theory the mutations that cause genomic variation are what drives evolution. These mutations could occur randomly or be affected by the environment. When mutations are random the resulting allele frequencies may differ from generation to generation. However, when an alteration is beneficial it increases the frequency of the allele, causing it to spread across the population.
These changes in allele frequency can lead to new species in the course of time. The new species could continue to evolve and become newer forms. This is a process called macroevolution. The development of a new species is usually due to changes in the environment which allow certain kinds of resources to become available or cause new environmental problems. The evolution of finches in the Galapagos Islands, for example, is due to the availability of new foods and the necessity to defend themselves from predators.
In a larger sense the term "evolution" can be described as any change in the characteristics of living organisms over time. The change could be small, such as the development of a new coloration or large, such as the creation of a new organ.
Scientists who believe in evolution theory generally agree that genetic change is crucial in the process of generating evolution. They also acknowledge that the process of evolution happens over a long time, usually millions of years. However, they differ over the role of various factors in speeding or slowing the process, like the influence of environmental pressures sexual selection, and 에볼루션 바카라사이트 mutation bias. Despite these differences, most 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 gathered evidence to support his theory of evolution. This evidence comes from fossils which show the evolution of organisms over time. Additional evidence can be found in the similarities between living organisms embryology, biogeography genetics and comparative anatomy.
The main proof of evolution is found in the evolutionary tree, which illustrates how species are related. Homologous structures are another evidence. They share a common structure but perform different functions in different species, for instance, the wing of a bird or bat. Evolution is evident in the way that various species adapt and evolve to similar environments. For instance, arctic-foxes and Ptarmigans sport white pelts during the winter months that blend in with the snow and ice. This is a type of convergent evolution that suggests that the species had common ancestral ancestors.
Vestigial structures are another piece of evidence. These are a part of an organism which may have served some purpose in the distant past. For example, the human appendix is remnants of an earlier organ that served to digest food. Natural selection causes these structures to shrink as they are no longer utilized.
Scientists have also collected evidence for evolution by observing and 에볼루션코리아 testing. The evidence for evolution is grouped into six categories: directly observed small-scale changes in biogeographic distribution and comparative anatomy, the fossil record, classification and genetics. Each of these categories offers compelling evidence for the evolution of life.
Many people are misinformed about the theory of evolution. However, it is an established fact. It is not just a theory; it is a potent collection of decades of observation and accumulated data that has been tested and proven. No matter what people believe or disbelieve about the theory of evolution scientists continue to research and gather new information in order to further know the story of life on Earth. This information will help scientists to understand how to avoid future catastrophes on the planet and how to best use the resources of our planet. It will also enable us to better meet the needs of all the people on this planet.
