https://evolutionkr.kr/ Evolution Explained The most fundamental notion is that living things change over time. These changes can help the organism survive, reproduce, or become more adaptable to its environment. Scientists have used genetics, a brand new science to explain how evolution occurs. They have also used the science of physics to calculate how much energy is required to create such changes. Natural Selection To allow evolution to take place, organisms must be capable of reproducing and passing their genetic traits on to future generations. This is the process of natural selection, sometimes called "survival of the fittest." However the term "fittest" can be misleading because it implies that only the strongest or fastest organisms can survive and reproduce. In fact, the best adaptable organisms are those that are able to best adapt to the environment in which they live. Moreover, environmental conditions can change rapidly and if a population is not well-adapted, it will be unable to survive, causing them to shrink or even become extinct. Natural selection is the most important factor in evolution. This occurs when desirable phenotypic traits become more common in a given population over time, which leads to the development of new species. This process is driven by the genetic variation that is heritable of organisms that results from mutation and sexual reproduction as well as the need to compete for scarce resources. Any force in the world that favors or defavors particular traits can act as an agent that is selective. These forces can be biological, such as predators, or physical, for instance, temperature. Over time populations exposed to different agents are able to evolve different from one another that they cannot breed together and are considered separate species. Although the concept of natural selection is straightforward but it's not always clear-cut. The misconceptions regarding the process are prevalent, even among scientists and educators. S
