Near-collapse of the #GeomagneticField may have contributed to atmospheric oxygenation and #animal radiation in the #Ediacaran Period https://www.nature.com/articles/s43247-024-01360-4

"the planet’s magnetic field was at a record low—around 30 times lower than today—for 26 million years starting around 565 million years ago. Such a drastic dip in magnetic field intensity could have had massive implications"

A Magnetic Low May Have Paved the Way for Complex Life

Multicellular life blossomed when Earth’s magnetic field was at an all-time low.

Earth's anisotropic inner core structure driven by dipole geomagnetic field, reveals study

A geomagnetic field is generated in Earth's interior and extends into outer space to protect Earth from cosmic radiation and the charged particles of solar wind. The magnetic field is generated by the convection of charged molten iron fluids in Earth's outer core.
