TAMPA, Fla., June 4 (UPI) -- A U.S.-led international research team says it's confirmed one key element that produced life on Earth -- phosphorous -- was carried here on meteorites.
Team leader Matthew Pasek, a geology professor at the University of South Florida, said their research suggests during the Hadean and Archean eons -- the first of the four principal eons of the Earth's earliest history -- a heavy bombardment of meteorites provided reactive phosphorus that when released in water could be incorporated into prebiotic molecules.
