<p>We start todays episode at the end of the world with Professor of Earth System Evolution, Ben Mills. Soon we're looking at his incredible grid cell model of the Earth and watching 537 million years of evolution play out in pixels: continents drifting, plants evolving, ice sheets growing, CO2 falling, climates flipping. Ben then really shows us something cool: a simulation wherein we build, or rather terraform, an exoplanet from scratch into a habitable planet. In realtime we seed a lifeless world with cyanobacteria... wait for oxygen... drop in algae, tinker with plants... And how did we go? Well, let's just say we're glad Gaia took care of this all on our planet, because left to us three, we're probably not making it out of the Snowball...</p><p>If you haven't listened to part 1 yet, don't start this episode until you've done that!!!
