Correct: The formation of nucleotides from inorganic substances further supports the hypothesis that life's building blocks formed before living cells existed. A: Not experimentally testable. C: Biogenesis concerns existing life producing life. D: Cell theory does not explain the origin of life. Concept: Experimental evidence supporting chemical evolution.**
