Gran Salto

"...In that transition between the dead organic combination and the similar that is alive lies the great, incomprenhensible mystery... In that leap from the dead to the living lies the mysterious break of continuity wich defies our understanding. Between the chemically definable protein molecule and the living bacterial cell there is a gap of understanding far greater than between the first living cell and man".

Hans Zinsser, Rats, lice & History. 1935
