Did an Asteroid Boost Life on Earth?

How did a gigantic asteroid impact 3.26 billion years ago benefit life on Earth? The S2 impactor was 200 times bigger than the meteor that caused the dinosaur extinction, so it seems counterintuitive for it to have had a positive impact on life. However, this meteor delivered large amounts of phosphorus to our planet, and also caused a tsunami that dredged up iron from the ocean floor. These two nutrients helped some single celled organisms to flourish in the aftermath of the impact!
