Experimental Snowball Earth Viscosity Drives the Evolution of Motile Multicellularity

During the 70-million-year span of the Cryogenian Snowball Earth glaciations, low ocean temperatures beneath global sea ice increased water viscosity up to fourfold.

Why The Harsh Snowball Earth Kick-started Our Earliest Multicellular Ancestors

For a billion years, single-celled eukaryotes ruled the planet. Then around 700 million years ago during Snowball Earth — a geologic era when glaciers may have stretched as far as […]

What Turned Earth Into A Giant Snowball 700 Million Years Ago?

Australian geologists have used plate tectonic modelling to determine what most likely caused an extreme ice-age climate in Earth’s history, more than 700 million years ago.
