https://evolutionkr.kr/ Evolution Explained The most fundamental notion is that living things change over time. These changes help the organism survive or reproduce better, or to adapt to its environment. Scientists have used the new genetics research to explain how evolution operates. They also have used the physical science to determine how much energy is needed for these changes. Natural Selection In order for evolution to take place for organisms to be capable of reproducing and passing their genes to future generations. Natural selection is sometimes called "survival for the strongest." However, the term can be misleading, as it implies that only the fastest or strongest organisms will survive and reproduce. The most adaptable organisms are ones that are able to adapt to the environment they live in. Furthermore, the environment can change quickly and if a population is no longer well adapted it will be unable to survive, causing them to shrink, or even extinct. The most fundamental element of evolution is natural selection. This happens when phenotypic traits that are advantageous are more common in a given population over time, resulting in the evolution of new species. This process is driven by the heritable genetic variation of organisms that results from mutation and sexual reproduction as well as the competition for scarce resources. Any force in the world that favors or disfavors certain characteristics can be an agent of selective selection. These forces could be physical, such as temperature, or biological, like predators. Over time, populations that are exposed to different agents of selection may evolve so differently that they are no longer able to breed together and are considered to be distinct species. Natural selection is a basic concept, but it can be difficult to understand. Even among educators and scientists there are a lot of misconceptions about the process. Surveys have shown that students' understanding levels of evolution are only weakl
