Detailed explanation-1: -Overproduction is a driving force in natural selection, as it can lead to adaptation and variations in a species. Darwin argued that all species overproduce, since they have more offspring than can realistically reach reproductive age, based on the resources available.
Detailed explanation-2: -If a trait results in more offspring who share the trait, then that trait is more likely to become common in the population than a trait that arises randomly.
Detailed explanation-3: -For speciation to occur, two new populations must be formed from one original population, and they must evolve in such a way that it becomes impossible for individuals from the two new populations to interbreed.
Detailed explanation-4: -Which of the following statements is accurate if we view evolution both as a pattern and a process? To study evolution as a pattern we draw on information from many other scientific fields, while to study evolution as a process we study factors that cause changes in populations.
