The key difference between microevolution and macroevolution is that the microevolution includes small-scale evolutionary changes especially within a single species population while the macroevolution includes large-scale evolutionary changes that lie beyond the boundaries of single species population over a longer period.
Evolution is a natural process that takes place on its own over a long period of time. Evolutionists and creationists have different views over how different species of organisms came into existence and how they evolved from primitive species. Accordingly, evolutionists are those who believe in the survival of the fittest and the Darwinian theory of selection and rejection while creationists are people who reject this theory though accepting the changes in certain species of animals that take place in a lifetime. Moreover, creationists describe these changes as microevolution whereas conveniently disagree with macroevolution, which is what is propounded by the theory of evolution. However, both microevolution and macroevolution involve the same principles and occur due to the same mechanisms; mutation and natural selection. But, their scales of the evolutionary changes are different.
