New evidence supports 'Snowball Earth' as trigger for early animal evolution

Researchers found a significant spike in marine phosphorus concentrations from 750 to 635 million years ago, linked to Snowball Earth glacial events. This increase in nutrient levels is believed to have facilitated the emergence of complex life, including animals, by driving oxygen production and ocean-atmosphere system shifts.
