Multiple studies demonstrate that the severe Cryogenian glaciations severely disrupted marine and terrestrial habitats, while simultaneously serving as evolutionary drivers that shaped global biodiversity.
The retrieved literature consistently supports the claim that Cryogenian glaciations drastically impacted global biodiversity, showing how these extreme climate events drove evolutionary splits, created novel glacial habitats (such as cryoconite pans), and acted as 'diversity pumps' for early eukaryotic and microbial life. No papers refute this relationship.
