The fossil record is a testament to extinct fauna no longer present on Earth. Certain areas of the planet have always had high species diversity (evident from fossils and catalogs of current species diversity). Which of the processes listed likely contributed to the patterns of animal diversity we see

The processes that likely contributed to the patterns of animal diversity we see is LOCAL AND GLOBAL EXTINCTION EVENTS.

Extinction event is when a large number of multicellular organisms of same species die within a short period of time reducing the number of such organisms in circulation in the ecosystems.

Extinction event can be (all over the world) or local (within a speculated geographic location).

Causes of extinction includes; population growth,habitat loss,over consumption, population and introduction of new species.
