The Evolution Site
The theory of natural selection as the foundation of evolution is the unifying force in the current biology. It brings together disciplines such as microbiology, palaeontology, genetics and 에볼루션 코리아 palaeontology.
However the study of evolutionary theory is often controversial and the resulting misinformation can confuse people regarding its basic concepts. This Web site helps to clarify the fundamental concepts.
What is Evolution?
The modern conception of evolution focuses on the gradual and cumulative changes that happen within populations over time. These changes are caused by natural selection, which increases the amount of organisms that possess beneficial traits that allow them to survive and reproduce in a specific environment. These organisms produce more offspring as a result of the positive traits. This causes the genetic changes that can eventually lead to the formation of new species.
The term "evolution" is often ascribed to the notion of "survival of the fittest" which means that people who are most well-adapted to a specific set of environmental conditions will have an advantage over those who aren't adapted to the environment. This is only one of the many ways that evolution can happen.
Another popular way in which the term "evolution" is used is to suggest that a species will invariably progress from one state of being to the next state of being. This type of view of evolution is known as anagenetic or cladogenesis. The definition of evolution in science is not in agreement with this view. The scientific theory of evolutionary change focuses instead on the changes that occur in populations over time. These changes are the result of mutations that produce natural selection and genetic variation.
Some scientists, including the great Charles Darwin, advocated this view of evolution. Others, notably Alfred Russel Wallace, who developed the theory of macroevolution believed that this was the only way that the higher forms of life could be derived from lower ones.
A theory must stand up to rigorous tests and evidence in order to be considered as a theory. The evidence of evolution has stood the test of time and has been supported by a myriad of studies across various scientific disciplines, from biology to geology to chemistry to astronomy. Evolution is a fundamental concept in science and is believed by the majority of scientists across the world. Many people are misinformed about the nature of evolution theory, especially how it relates with religion.
What is the Theory of Evolution?
Evolution is an explanation for how living things change with time. It is based on a variety of well-established observable facts: that more offspring are produced than could possibly survive and that individuals differ from one another in their physical characteristics (phenotype) and that distinct traits have different rates of survival and reproduction and can be passed down to future generations. These observations are supported by an increasing body of evidence derived from molecular biology, 에볼루션 코리아 palaeontology 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 as an explanation for how organisms adapt to their physical and biological environments. It is the most widely accepted and validated theory in science. Its theories have been proven out by the fact that, for instance, more complex organisms have fewer genetic mutations than simpler ones. Additionally, the more successful an organism is at being able to reproduce and survive and 에볼루션사이트 reproducing, the more likely it is to pass its genes to the next generation.
Some people are against evolution because they believe it implies that there is no meaning to life. However, many scientists who are also religious believers such as the renowned Cambridge palaeontologist Simon Conway Morris, 에볼루션 believe that evolution is not only compatible with faith in God but is enhanced by it (BioLogos 2014).
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 wide variety of phenomena, such as phylogenetics, genomics and the formation and function of fossils.
The term "theory", which is often misinterpreted is a reference to a scientific hypothesis that has been tested and refined over a period of time. Scientists test hypotheses by repeating the experiments or observations that led them to the conclusion. The theory of evolution has been repeatedly proven out and so have the theories of Copernican, germ theory, and atomic theory.
What is the Process of Evolution?
The process of evolution is a gradual change in the proportions of genetically diverse individuals within a species over time. This change is a result of the natural selection of individuals that are more adapted to their environment. The individuals who are more adaptable have a greater chance of survival and reproduction. As more people survive and reproduce, their genes are more common in the general population. This is sometimes described as "survival of the fittest."
According to the theory of evolution, the mutations that produce genomic variation are the raw material for evolution. These mutations may occur randomly or under the influence of the environment. When mutations are random, the frequency of the resultant alleles could differ from generation to generation. In contrast, when the mutation is beneficial it can increase the frequency of the allele, causing it to spread across the population.
Over time, these shifts in allele frequencies can result in the creation of new species. The new species will evolve and develop into newer forms. This is known as macroevolution. The formation of a new species is often due to changes in the environment that provide certain types of resources available or 에볼루션 바카라 무료 cause new environmental problems. For instance, the development of finches in the Galapagos Islands is a result of the availability of various food sources and the need to protect themselves from predators.
In a larger sense it is 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, or even massive, like the development of a brand new organ.
Scientists who believe in the theory of evolution generally agree that genetic changes are important in the process of generating evolution. They also believe that evolution is a process that happens in time, typically over a period of millions of years. However, they differ over the importance of different factors that speed up or slow down this process, such as the influence of environmental pressures sexual selection and 에볼루션 코리아 (Http://Daoqiao.Net) mutation bias. Despite these differences, the majority of scientists believe that evolution is happening and the evidence to prove this is overwhelming.
What is the Evidence of Evolution?
Since Darwin's time, scientists have gathered evidence to support Darwin's theory of evolution. This evidence comes from fossils that show the evolution of organisms over time. Other evidence is found in similarities among living organisms embryology, biogeography, genetics and comparative anatomy.
The most important proof of evolution is found in the evolutionary tree, which demonstrates how species are related. Another source of evidence is homologous structures, which share a similar structure in different species but have distinct functions such as the wings of bats and birds. Evolution is evident in that different species adapt and develop to similar environments. For instance, arctic-foxes and Ptarmigans have white pelts during the winter months that blend into the snow and ice. This is a kind of convergent evolution, which suggests that the species have common ancestors.
Another source of evidence is the existence of vestige structures, which are unutilized organs that may have served a purpose in the distant ancestors. The human appendix, for instance, is a vestige from an organ that once used 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 experimenting. The evidence for evolution can be classified into six distinct categories: directly observable 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.
While many people are misinformed about the theory of evolution, it is an established fact. It is not a theory but a significant collection that is founded on decades of observation. Scientists continue to gather and analyze new data to better understand the evolution of Earth's existence regardless of whether people believe in the theory of evolution or not. This information will allow scientists to better understand how to avoid future global catastrophes, and how to use the resources on our planet. It will also enable us to better serve the needs of the people on this planet.
