In 2007, scientists Matthew A. Pasek, Jason P. Dworkin, and Dante S. Lauretta published their study on the corrosion of the meteorite mineral schreibersite (FeNi)3P. These scientists proposed the idea that the corrosion of this meteorite mineral released a phosphite-free radical that could form activated polyphosphates and phosphorylate organic compounds. Many life-forms have phosphorus in them in the form of ATP, DNA, and phospholipids. What does this study suggest about the origin of organic biological molecules on early Earth? A. DNA, ATP, phospholipids, and all other biological molecules developed on meteorites before they came to Earth. B. The substances brought to Earth from meteorites may have played a vital role in the first organic biological molecules. C. All organic biological molecules developed from the mineral schreibersite. D. Phosphorus was the only substance that created biological molecul
