-
A.
Great Oxidation Event
chosen
The Great Oxidation Event was a pivotal period in Earth’s early history when atmospheric oxygen levels rose dramatically due to photosynthetic microorganisms, fundamentally transforming the planet’s environment and biosphere.
-
B.
Toarcian Oceanic Anoxic Event
The Toarcian Oceanic Anoxic Event was a major Early Jurassic global environmental crisis marked by widespread marine oxygen depletion, significant carbon-cycle disruption, and associated mass extinctions.
-
C.
Great Ordovician Biodiversification Event
The Great Ordovician Biodiversification Event was a profound evolutionary radiation during the Ordovician Period that saw a dramatic increase in marine biodiversity and the establishment of many major animal groups in Paleozoic oceans.
-
D.
Permian–Triassic mass extinction
The Permian–Triassic mass extinction was the most severe biodiversity crisis in Earth's history, wiping out the majority of marine and terrestrial species around 252 million years ago and marking the boundary between the Paleozoic and Mesozoic eras.
-
E.
Cambrian explosion
The Cambrian explosion was a relatively brief period around 541 million years ago when most major animal groups rapidly appeared in the fossil record, dramatically increasing the complexity and diversity of life on Earth.
