About 700m years ago, the Earth froze over entirely – now we may know why Researchers believe huge volcanic eruptions, and the absence of plants, turned our planet into one giant snowball It’s hard to believe, but about 700m years ago it’s thought that our planet completely...

Biosignatures of diverse eukaryotic life from a Snowball Earth analogue environment in Antarctica - Nature Communications The supraglacial meltwater ponds of the McMurdo Ice Shelf, analogues for proposed Cryogenian period eukaryotic refugia, are shown to host diverse and varied eukaryotic communities.
