A new study from Western University explores the possibility that Earth's earliest life forms may have been cultivated by a meteorite impact event.

In 1980, Alvarez and colleagues proposed that, in the transition from the Cretaceous to Paleogene, a large impactor collided with Earth being the cause of the mass extinction occurred at the limit K/Pg.

It is now understood that the accretion of terrestrial planets naturally involves giant collisions, the moon-forming impact being a well known example.
