Mass Extinction Events
- Five mass extinction events have drastically altered Earth's biodiversity.
- These events are identified through fossil records, geological markers, and shifts in isotope ratios.
Ordovician-Silurian Extinction
- The Ordovician-Silurian extinction, the first major event, eliminated 85% of marine species.
- Global cooling and resulting habitat loss are considered primary causes.
Late Devonian Extinction
- The Late Devonian extinction, a series of pulses, affected 75% of species, especially marine life.
- Global cooling and oceanic anoxia from plant evolution are suspected causes.
