Microorganisms that crashed to Earth embedded in the fragments of distant planets might have been the sprouts of life on this one, according to new research from Princeton University, the University of Arizona and the Centro de Astrobiología (CAB) in Spain. The researchers provide the strongest support yet for "lithopanspermia," the idea that life came to Earth — or spread from Earth to other planets — via meteorite-like planetary fragments cast forth by disruptions such as volcanic eruptions and collisions with other matter.
