Definition==
Macroevolution is the idea of major evolutionary change to whole species of organisms over time. It is essentially the end result of microevolution, but there is technically never really an end to evolution as there are constant mutations and little changes going on in individuals and populations.

Currently there are thousands of examples that we could elaborate upon, as this happens on kingdom wide basis.
In the above video the instructor describes the changes that manatees have undergone as a species.
