Story summary

The breakup of the supercontinent Nuna triggered shallow, temperate, oxygen-rich seas during Earth's Boring Billion (1.8–0.8 billion years ago), creating conditions for complex life.
A study published on October 27 in Earth and Planetary Science Letters shows shifting tectonic plates shortened subduction zones, reducing carbon dioxide emissions and cooling the planet.
The cooling stabilized nutrient- and oxygen-rich marine environments, enabling evolution and diversification of life, according to co-author Juraj Farkaš.
