Scientists believe in natural selection because it is a well-supported and extensively studied mechanism that explains how species evolve and adapt to their environment over time. The evidence for natural selection comes from various fields of study, including genetics, Paleontology, and ecology, providing a strong foundation for understanding the diversity of life on Earth. Additionally, the observations of natural selection in action, such as antibiotic resistance in bacteria or beak size in finches, further support its validity as a key driver of evolution.
AnswerCreation scientists fully acknowledge natural selection as a mechanism of biological change.At the same time, they believe that natural selection only acts upon genetic information that already exists. Natural selection does not create new information. The variability that created the Galapagos Finch differences, as well as all the different dog breeds thus already existed in those populations.Natural selection alone cannot "make microbes into men." Although evolutionary biologists agree that natural selection does not introduce new genetic information, they concur the second mechanism of evolution, random mutation, DOES introduce new information both through gene duplication and by altering gene function, as has been observed.[Part of a specific article on the creationist website "WikiCreation" deals with this question. Please refer to the attached link for the article.]
Charles Darwin is the scientist who is most widely recognized for his contribution to evolutionary theory through the study of natural selection. Darwin's work provided the foundation for our understanding of how species evolve over time.
Mathematical analysis in genetics and comparative genomics can show scientists to what degree a particular genetic sequence resulted from selection pressures at a given time in the evolutionary history of the organism under consideration.
This process is called natural selection. It is the mechanism by which traits that provide a survival or reproductive advantage to an organism become more common in a population over time.
Natural selection can only work on genetic variation that already exists. So mutation comes first, then natural selection.
yes scientists believe that because of the fact they are making a comback in their species.
" Evolutionists? " Believe in? " Two words/phrases that are ideological in nature and have no place in a scientific discussion. Evolutionary scientists accept the overwhelming and convergent evidence for the theory of evolution by natural selection. This is the best explanation we have for the adaptive changes seen in evolution.
Since the natural selection is a theory, we can not apply a theory as a science. Even though some scientists believed in natural selection: think of Nazi scientists, Soviet scientists, etc. They were 100% evolutionist believers. Nobody yet seen atoms but we believe that they exist...strange. We apply faith in some modern science...hmmm...
Charles Darwin
The four pieces of evidence that scientists point to as proof of natural selection are the fossil record, biogeography, homologous structures, and observable natural selection in action. These pieces of evidence all support the idea that organisms have evolved over time through the process of natural selection.

Many scientists believe that natural selection is the most important mechanism driving evolution. This process favors traits that enhance an organism's survival and reproductive success, leading to changes in populations over time.
Alfred Wallace
natural selection
One was Darwin's theory was the process of evolution by natural selection and the second one was Lyell's theory was that animals can adapt and change their traits to fit the environment.

Charles Robert Darwin and Alfred Russel Wallace first purposed the theory of evolution by natural selection, but the theory accepted by most scientists today has been modified a bit since Darwin and Wallace's day.
