A recent study published revealed that the surge in oxygen levels between 445-485 million years ago led to three-fold increase in biodiversity of the world.

• This explosion in biodiversity is referred to as ‘Great Ordovician Bio Diversification Event.
• This even brought about rise of various marine life, tremendous change across species families and types, as well as changes to Earth, starting at bottom of ocean floors.

The GOBE involved a significant increase in the diversity of the phytoplankton and the development of a diverse zooplankton (including planktotrophic larvae from a range of invertebrate clades).
