Weak Magnetic Field 590 Million Years Ago Linked to Oxygen Boost and Early Life Diversification

New studies suggest Earth's reduced magnetic field may have facilitated a rise in oxygen levels, supporting complex life during the Ediacaran period.

Researchers found Earth's magnetic field was significantly weaker between 591 and 565 million years ago, coinciding with a rise in oxygen and biodiversity.
The weakening of the magnetic field potentially allowed more hydrogen to escape Earth's atmosphere, increasing oxygen levels in the oceans and air.
This period of low magnetic field strength overlaps with the emergence of Ediacaran fauna, marking a crucial phase in the evolution of complex life.
Studies indicate this oxygen increase could be linked to the diversification of life forms during the late Ediacaran period.
The findings challenge previous assumptions about the detrimental effects of a weak magnetic field on early life.
