Story summary

Researchers from the University of Sydney and the University of Adelaide show that Earth’s tectonic movements shaped the evolution of complex life between 1.8 and 0.8 billion years ago.
The Nuna supercontinent broke up 1.46 billion years ago, doubling continental shelf areas and creating shallow, oxygen-rich seas.
The resulting reduction in volcanic carbon emissions cooled the climate and promoted conditions for photosynthetic life, challenging the idea of the ‘Boring Billion’.
