“So many things could have happened in a different way that we wouldn't be here at all, both individually, for sure, and certainly as a species.”

From an asteroid that wiped out the dinosaurs to a tectonic collision that cooled the planet, Carroll unpacks the unbelievable random events and unpredictable pivots that caused the planetary chaos leading to our current civilization.
