The Evolution Site

The theory of evolution based on natural selection is the unifying force of modern biology. It connects disciplines such as genetics, microbiology and Palaeontology.

However the study of evolutionary theory is often controversial, and the misinformation that results can confuse people regarding the fundamentals of evolution. This site clarifies essential concepts.

What is Evolution?

Modern evolutionary theory focuses on the gradual and cumulative changes that occur in populations over time. These changes are the result of natural selection, which increases the number of organisms that have beneficial traits that enable them to live and reproduce in a specific environment. In turn, these organisms have more offspring than those that don't possess the beneficial characteristics. This leads to a genetic change that can eventually lead to the development of new species.

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

Another popular way to use the word evolution is to suggest that species are able to move from one stage to the next. This view of evolution is called anagenetic or cladogenesis. This theory is not supported by the definition of evolution that is scientifically accepted. Instead, the scientific theory of evolution focuses on changes that happen 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 idea. Alfred Russel Wallace who developed the macroevolution theory believed that this was the only way in which the higher forms of living could have evolved.

To be able to be referred to as a theory, it must be capable of surviving rigorous tests and evidence. The evidence for evolution has withstood the test of time and has been supported by countless studies in many scientific disciplines, ranging from geology to biology to astronomy. In fact evolution is considered to be one of the cornerstones of science today, and it is backed by the majority of scientists across the globe. Many people are confused about the nature of the theory of evolution particularly how it is connected 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 variety of well-established and observable facts: that more offspring are produced than can possibly survive and 바카라 에볼루션 룰렛 - borregaard-pena.blogbright.net, that individuals differ from one another in their physical characteristics (phenotype) and that distinct characteristics result in different rates of reproduction and survival and can be passed down to the next generation. These observations are supported by the growing body of evidence from molecular biology, palaeontology, functional morphology, climatology and geology.

The theory of evolution based on natural selection was conceived independently by Charles Darwin and Alfred Russel Wallace in the late 19th century to explain the reason that organisms are adapted to their biological and physical environments. It is the most widely supported and tested theory in the field of science. Its predictions have been proved out by the fact that, for example complex organisms have less genetic mutations than simpler ones. The more successful an organism gets in terms of its longevity and reproducing, the more likely it is to pass its genes on to future generations.

Some people are against evolution because they believe that it suggests that there is no purpose 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.

In actual fact, a significant number of highly trained evolutionary biologists, including some who are renowned evangelical Christian leaders have been involved in the development and testing of the theory of evolution. Many of them have contributed to the understanding of a vast variety of phenomena, including phylogenetics and genomics, and the development and role of fossils.

The word "theory" is often used incorrectly to mean a speculation or guess however it actually is a scientific hypothesis that has been thoroughly developed and tested over time. Scientists test hypotheses through repeating the experiments or observations that led them to the conclusion. Therefore, 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 the gradual change over time in the percentage of genetically distinct individuals within a certain species. This change is a result of the natural selection of individuals that are more well-adapted to their environment. The better-adapted individuals have a higher chance of survival and reproduction. As more of these individuals survive and reproduce, their genes are more prevalent in the general population. This process is sometimes called "survival for the strongest."

According to the theory of evolution the causes of mutations that result in genomic variation are what triggers evolution. These mutations may occur at random or under the influence of the environment. When mutations occur randomly, the allele frequencies may vary from generation to generation. If a mutation is beneficial it can increase the frequency of the allele, causing the allele to spread throughout the population.

Over time, these shifts 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 called macroevolution. The development of new species is typically due to changes in the environment that make certain resources accessible or creates new environmental problems. For instance, the rise 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 wider sense, evolution can be defined as any change in the characteristics of living organisms over time. The change could be subtle, like the development of new coloration or dramatic, like the formation of an organ.

Scientists who accept evolution theory 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, usually over a period of millions of years. They differ on the importance of various factors that could speed up or slow down the process. For instance, the role of sexual selection, environmental pressures and mutation bias. Despite these differences, the majority of scientists believe that evolution is real and the evidence to prove it is overwhelming.

What is the Evidence of Evolution?

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

The evolutionary tree is the best way to prove evolution. It shows how different species are related. Another source of evidence is homologous structures, which have similar structure in different species, but serve different purposes such as the wings of birds and bats. Evolution is also evident in the fact that different species adapt and grow to similar environments. For example, arctic-foxes and Ptarmigans wear white seasonal pelts which blend with snow and ice. This is a form of convergent evolutionary process which suggests that the species share ancestors.

Vestigial structures are another piece of evidence. They are the remains of an organism that may serve a function in the distant past. For instance, the human appendix is a vestige of a once-used organ that was used to digest food. Natural selection causes the structures to shrink when they cease to be used.

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

Many people are misinformed about the theory of evolution. However, it's a fact. It is not a theory but a significant collection of evidence founded on decades of observation. No matter what people believe or deny about the theory of evolution scientists continue to study and collect new data in order to further know the story of life on Earth. This knowledge will allow scientists to better understand how we can avoid future global catastrophes, 에볼루션코리아 and how best to make use of the resources of our planet. It will also enable us to better meet the needs of all the people living on this planet.
