    Biodiversity generally tends to cluster in hotspots, and has been increasing through time but will be likely to slow in the future. Rapid environmental changes typically cause mass extinctions.

Since life began on Earth, five major mass extinctions and several minor events have led to large and sudden drops in biodiversity. The Phanerozoic eon (the last 540 million years) marked a rapid growth in biodiversity via the
