Asteroid impact 3.2 billion years ago "aided" life

An asteroid 200 times larger than the one that may have caused the extinction of the dinosaurs hit the earth 3.26 million years ago.  It supposedly boiled off the surface water of the ocean, heated the atmosphere and would have shut down photosynthesis.  It also mixed up the ocean water forcing mixing of deep iron rich water with iron poor surface water.
The article claims that this aided life.  It would have been a boon to oxygen generating photosynthesis that uses iron in bacterial chlorophyll.
What should be of interest to everyone is how this explains the results of the recent LUCA research.

Last July this article was put up on TO.  They used genes that may have duplicated before the last common ancestor of extant life existed to estimate that LUCA likely existed around 4.2 billion years ago.  It would have meant that there were sophisticated lifeforms with the universal genetic code existing soon after the earth cooled enough to have liquid water.  One other conclusion was that LUCA likely existed with many other lineages of life that had been evolving the genetic code to the extent that it had achieved in LUCA.  The evidence indicated that the LUCA may have evolved from chemotrophes, but may have not been a chemotrophe (it had genes needed for photosynthesis).  Apparently, the researchers thought that chemotrhophes reevolved in both Archaea and eubacteria.  Around 3.2 billion years ago there seems to have been a mass extinction of existing life forms and only two lineages derived from LUCA survived to produce all the extant lifeforms on earth.  This Asteroid hit at around the right time to have caused this mass extinction that nearly ended life on this planet.
Figure one of the Nature article indicates that around 3.2 billion years ago only one lineage of Eubacteria and one lineage of Archaea survived to subsequently diverge into what we have today.  I don't think that the Asteroid impact "aided" life, but it did reduce the possibilities that life had, and made the evolution of extant lifeforms possible including us.  Without that asteroid impact life may have evolved very differently than it did.
