Evolutionary change above the species level. Examples of macroevolutionary change include the origin of a new group of organisms through a series of speciation events and the impact of mass extinctions on the diversity of life and its subsequent recovery .

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.

mountains can affect the climate of nearby lands. in some areas, mountains block rain, so that one side of a mountain range may be rainy and the other side may be a desert. much of airborne moisture falls as rain on the windward side of mountains.
