The adaptive radiation of birds in the Lower Cretaceous, teleosts in the Cretaceous, flowering plants in the Upper Cretaceous, mammals in the Eocene, moths in the Cretaceous are striking examples of macroevolution. However, there are even more important events in the history of life. An interesting list was prepared by Maynard Smith and Szathmáry, which they called the major transitions in evolution. They did the list twice.
