This is the macro scale study of patterns of evolution of life on Earth, including the continuum of evolutionary development in the macro scale, extinctions, and adaptive contexts like speciation from original species, in which the combination of species and subspecies forms the macroevolutionary idiom.
Examples of Macroevolution:
Paleontological context: The Cambrian Explosion was one of the great events in macroevolution, the profusion of new forms of life in the world's oceans.|
Extinction context: The extinction of the dinosaurs created a macroevolutionary raffle as to which species would dominate the new environment. At one stage, giant flightless predatory birds were top predators.
