It has been argued that the historical nature of evolution makes it a highly path-dependent process. Under this view, the outcome of evolutionary dynamics could have resulted in organisms with […]

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 […]

Examining The Role Of Oxygen-binding Proteins On The Early Eevolution Of Multicellularity
Oxygen availability is a key factor in the evolution of multicellularity, as larger and more sophisticated organisms often require mechanisms allowing efficient oxygen delivery to their tissues. One such mechanism […]
