Maybe a complete understanding of life and its evolution will never be possible. However, this will not certainly stop scientists from seeking the secret of the origin of life. Whitesides recently expressed the current state of understanding of the origin of life in frank words,
"Most chemists believe, as do I, that life emerged spontaneously from mixtures of molecules in the prebiotic Earth. How? I have no idea. Perhaps it was by the spontaneous emergence of “simple” autocatalytic cycles and then by their combination. On the basis of all the chemistry that I know, it seems to me astonishingly improbable.".
