The breakup of the ancient supercontinent Nuna during Earth's 'Boring Billion' period created shallow seas, reduced volcanic CO2 emissions, and stored carbon in ocean sediments, fostering stable, oxygen-rich environments that likely contributed to the emergence of complex life, including eukaryotes.

Scientists have discovered ancient microfossils in Western Australia that provide new insights into the rise of complex life during the Great Oxidation Event. These microfossils, resembling algae, suggest a significant leap in life's complexity and could redefine our understanding of life's evolution and the potential for complex life forms in the universe. The findings, published in the journal Geobiology, offer direct evidence linking environmental change during the Great Oxidation Event with an increase in the complexity of life. Further research is needed to confirm if the microfossils represent early eukaryotic organisms, which would push back the known eukaryotic microfossil record by 750 million years. The discovery has implications for understanding the origins of complex life on Earth and the search for life elsewhere in the universe.

Microfossils discovered in Western Australia provide direct evidence of a rise in the complexity of life during the Great Oxidation Event, a time when oxygen concentration increased on Earth around 2.4 billion years ago. The microfossils resemble algae and suggest the presence of early eukaryotic organisms, pushing back the known eukaryotic microfossil record by 750 million years. The findings have implications for understanding the timeline of complex life formation on Earth and the potential for complex life elsewhere in the universe.
