https://evolutionkr.kr/ Evolution Explained The most fundamental idea is that all living things alter over time. These changes can assist the organism survive or reproduce better, or to adapt to its environment. Scientists have used genetics, a science that is new to explain how evolution works. They have also used the physical science to determine how much energy is needed to trigger these changes. Natural Selection To allow evolution to occur for organisms to be able to reproduce and pass on their genetic traits to the next generation. This is a process known as natural selection, often referred to as "survival of the best." However, the term "fittest" can be misleading as it implies that only the most powerful or fastest organisms will survive and reproduce. The most adaptable organisms are ones that can adapt to the environment they live in. The environment can change rapidly, and if the population isn't properly adapted, it will be unable endure, which could result in the population shrinking or becoming extinct. The most important element of evolutionary change is natural selection. This occurs when phenotypic traits that are advantageous are more common in a given population over time, which leads to the evolution of new species. This process is driven by the heritable genetic variation of living organisms resulting from sexual reproduction and mutation and the competition for scarce resources. Any element in the environment that favors or hinders certain traits can act as an agent that is selective. These forces can be physical, like temperature, or biological, such as predators. Over time populations exposed to various agents are able to evolve different that they no longer breed and are regarded as separate species. While of natural selection is straightforward but it's difficult to comprehend at times. Uncertainties about the process are widespread, even among scientists and educators. Studies have found that there is a small correlation between students'
