Universally accepted, microevolution has limits for what it can explain. These limits do not reach the center where the controversy lies - the Thesis of Common Ancestry was popularized by Charles Darwin. Darwin believed that the world we see today has come to us through an evolutionary process called natural selection. Through genetic mutation, species adapt and develop because the strongest of a species will survive and pass on their DNA to their successors. Macroevolution is the belief that all development — from the first moments of the universe, the formation of stars and planets, to the eventual emergence of simple bacteria, to the most complex human being is explainable through this naturalistic transformational process.
