The Evolution Site

The concept of natural selection as the basis of evolution is the defining factor in modern biology. It connects disciplines such as genetics, microbiology and Palaeontology.

However, the study of evolution is often controversial and the resulting misinformation can confuse people about the fundamentals of evolution. This Web site helps explain the most important concepts.

What is Evolution?

The current understanding of evolution is based on the gradual, cumulative changes that occur within populations over time. These changes are the results of natural selection. This is a process that increases the number of organisms with beneficial traits, which help them to thrive and reproduce in specific environments. In turn, these organisms produce more offspring than those that do not have the beneficial characteristics. This results in a genetic change that can eventually lead to the formation of new species.

The term "evolution" is often associated with "survival-of-the most 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 that evolution can happen.

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

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

A concept must be able stand against rigorous tests and evidence to be considered a theory. The evidence of evolution has stood up to the test of time and has been backed by countless studies in many scientific disciplines, ranging from biology to geology, chemistry to astronomy. Evolution is a cornerstone of science and is believed by a majority of scientists across the world. Many people have misconceptions regarding the nature of evolution theory and how it connects 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 range of well-established and observable facts: that more offspring are often created than are likely to survive and that individuals differ from each other in their physical characteristics (phenotype) and that various traits have different rates of reproduction and survival and reproduction; and that these traits can be passed down to future generations. These observations are backed by the increasing body of evidence from molecular biology, palaeontology, climatology, functional morphology and geology.

Charles Darwin and Alfred Russel Wallace independently conceived the theory of evolution based on selection in the middle of the 19th century as a reason why organisms are adapted their physical and biological environments. It is now the best-supported and widely-tested theory in all of science. Its predictions were proved by the fact that, for instance, more complex organisms are less susceptible to genetic mutations. The more successful an organism is in terms of surviving and reproducing, the more likely it will transmit its genes to the next generation.

Some people are against evolution because they believe that it implies that there is no meaning to life. However, many scientists who are also religious like the famous Cambridge palaeontologist Simon Conway Morris, believe that evolution is not only compatible with belief in God but also enhances it (BioLogos 2014).

Many highly skilled evolutionary biologists have been involved in developing and testing the theory of evolution, including several revered evangelical Christian leaders. Many of these researchers contributed to the understanding of a broad range of phenomena, including genomics and phylogenetics and also the formation and function of fossils.

The word "theory", which is often misinterpreted refers to scientific hypotheses that have been tested and refined over a period of time. Scientists test their theories by repeating experiments or observations that led to them. Thus the theory of evolution theory has been repeatedly proven, as have the corresponding theories of Copernican theory as well as atomic theory 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 the natural selection of individuals that are more well-adapted to their environment. The more adapted individuals have a better chance of survival and reproduction. As more of these people survive and reproduce, their genes become more common within the population. This is often described as "survival of the fittest."

According to the theory of evolution the mutations that cause genomic variation are the primary basis for evolutionary change. These mutations can occur at random or be affected by the environment. If mutations occur in a random manner, 에볼루션 사이트 - Sciencewiki.Science, the allele frequencies may vary from generation to generation. When an alteration is beneficial, it increases the frequency of the allele, 에볼루션 무료 바카라 causing it to spread through 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 process is 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 create new environmental problems. For instance, the rise of finches on the Galapagos Islands is a result of the abundance of food sources and the need to protect themselves from predators.

In a wider sense the term "evolution" can be described as any change in the character of living organisms over time. This change can be small or even the creation of a new coloration or even massive, like the formation of a new organ.

Scientists who believe in the theory of evolution generally agree that genetic change is crucial in the process of the process of generating evolution. They also agree that the process of evolution takes place over a lengthy period of time, often millions of years. They differ on the importance of various factors that could speed up or slow down this process. For instance the role of sexual selection, environmental pressures and mutation bias. Despite these disagreements, most scientists believe that evolution is real and that the evidence to prove it is overwhelming.

What is the Evidence of Evolution?

In the decades since Darwin's time, scientists have collected evidence to support Darwin's theory of evolution. Some of this evidence comes from fossils which demonstrate the changing features of living things over time. Other evidence is found in similarities between living organisms embryology, biogeography, genetics and comparative anatomy.

The most important proof of evolution is found in the evolutionary tree, which shows how different species are related. Homologous structures are another proof. They share a common structure but perform different functions in different species, like the wing of a bird or 에볼루션코리아 bat. Evolution is evident in that different species adapt and grow to similar environments. For example, arctic-foxes and Ptarmigans sport white fur coats which blend with snow and ice. This is a type of convergent evolutionary process, which suggests the species shared ancestors.

Another evidence point is vestigial structures, 에볼루션게이밍 which are unused parts of an organism which could have served a purpose in a distant ancestor. For instance the human appendix is remnants of an earlier organ that was used to digest food. Natural selection is a process that causes the structures to shrink when they cease to be used.

Scientists have also collected other evidence for 에볼루션 무료 바카라 evolution through observation and experimentation. The evidence for evolution is grouped into six categories: directly visible small-scale changes, biogeographic distribution, comparative anatomy, the fossil record, classification and genetics. Each of these provides convincing evidence that evolution of life has taken place.

Many people have misconceptions about the theory of evolution. But, it's a fact. It isn't simply a flimsy theory. It is a powerful collection of decades of observations and data that has been proven and tested. Scientists continue to gather and analyze new data to better understand the history of Earth's existence, regardless of whether people believe in the theory of evolution or not. This knowledge will allow scientists to better understand how we can avoid future global catastrophes, and how to use the resources of our planet. This will allow us to better serve the needs of all the people on this planet.
