Story summary

During the Ediacaran Period (630–541 million years ago), rocks in Morocco's Anti-Atlas Mountains reveal fluctuations in Earth's magnetic field.
The Yale University-led study finds magnetic poles moved up to seven degrees per million years, indicating instability.
Researchers say the instability could have influenced climate and the evolution of early life forms.
The findings offer a framework for understanding continental positions and Earth’s magnetic-field dynamics, with implications for predictions and resilience.
