Answer:
Macroevolution
Explanation:
Macroevolution has to do with the evolution above the species level. It is not based on a single specie (e.g. a single beetle specie) but on the tree of life (evolutuon of groups) to view the variations of the total beetle clade with its level on the phylogeny.
It deals with what is observed in life history on a large scale e.g. the origin and diversification of mammals, flowering plants radiation, long periods of stasis as seen in sharks and crocodiles,co-evolution e.t.c. It brings more understanding to life diversity and how frequent evolution occurs (swiftly or slowly).
It can be as a result of mutation, genetic drift, gene flow or natural selection.
