Macroevolution is a term used by evolutionists to describe the alleged, unobservable change of one kind of organism to another kind by natural selection acting on the accumulation of mutations over vast periods of time.
If you take a genetics course in any reasonable university (not one run by anti-evolutionists), you use fruit flies (Drosophila) to select for or against certain features, evolving a population rather quickly. Some anti-evolutions say that this is “microevolution,” which to a scientist is no different than “macroevolution.” The problem with the evolution denialist viewpoint is that fruit flies have a very short lifespan, so generations upon generations can be studied over a few weeks or months. If humans lived only 2 days, then we could observe evolution in humans.
