Detailed explanation-1: -Fitness, in other words, is the trait that natural selection “sees” and other traits change only because they are associated genetically with fitness and so get dragged along with the response to selection on fitness itself.
Detailed explanation-2: -Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.
Detailed explanation-3: -Natural selection is any selection process that occurs as a result of an organism’s ability to adapt to its surroundings. Artificial selection, on the other hand, is selective breeding that is imposed by an external entity, usually humans, in order to enhance the frequency of desirable features.
