While natural selection is a key mechanism of evolution, the term \u201cevolution\u201d itself refers to the broader process of change in the genetic composition of a population over time.<\/p>\n\n\n\n<p><strong>Explanation:<\/strong><\/p>\n\n\n\n<p>Natural selection is the process through which certain traits become more or less common in a population based on their impact on the organisms&#8217; ability to survive and reproduce in their environment. The main drivers of natural selection include <strong>variation<\/strong>, <strong>overpopulation<\/strong>, and <strong>adaptation<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Variation<\/strong>: This refers to the differences in traits among individuals in a population. Variations can arise due to genetic mutations, sexual reproduction, and environmental factors. Natural selection acts on these variations; individuals with traits that enhance survival and reproduction are more likely to pass those traits on to the next generation. Without variation, there would be no basis for selection.<\/li>\n\n\n\n<li><strong>Overpopulation<\/strong>: This concept refers to the phenomenon where a population produces more offspring than the environment can support. Overpopulation leads to competition for resources such as food, water, and shelter. Those individuals that are better adapted to the environment are more likely to survive and reproduce, thereby driving the process of natural selection.<\/li>\n\n\n\n<li><strong>Adaptation<\/strong>: This involves the process through which species evolve characteristics that better suit them to their environment over generations. Adaptations are the result of natural selection favoring certain traits that improve an organism&#8217;s fitness.<\/li>\n<\/ol>\n\n\n\n<p>On the other hand, <strong>evolution<\/strong> is the overarching outcome of the processes of natural selection and other mechanisms such as genetic drift, mutation, and gene flow. It describes the cumulative changes in the genetic makeup of populations over time. Therefore, while natural selection is a crucial factor that leads to evolution, evolution itself is not a cause of natural selection.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which would least likely be a cause of natural selectionAdaptationEvolutionOverpopulationVariation The Correct Answer and Explanation is : The least likely cause of natural selection from the options provided is evolution.
