Some researchers believe that, during the glacial marine cycle (650-535 million years ago), Earth was surrounded by ice sheets called “Snowball Earth.” which in turn influenced the climate and chemistry of the oceans, and slowed early life.

However, biotic lifeforms started to evolve when the Earth heated up and the Ediacara period started.

A research team from the University of Tohoku has further eluciended the evolutionary process of the transition from the Marine to the Ediacar Ice Age.

A team of researchers from Tohoku University has explored possible photosynthetic activities during the Aquatic Ice Age with the assistance of biomarker evidence.

A period of low productivity of photosynthetic organisms and bacteria consequently ensued.

And steranes of carbonates and loam after carbonate storage during the Early Ediacara Period pointed to the expansion of eukaryotes.

‘Environmental stress in a closed marine environment to the atmosphere, followed by high temperatures around 60 ° C, may have produced more complex animals in the aftermath.’ As a result, bacterial recovery was eukaryotic.

Snowball Earth

The Snowball Earth hypothesis proposes that during one or more of Earth’s icehouse climates, Earth’s surface became entirely or nearly entirely frozen, (wikipedia)


Climate change

Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. (wikipedia)
