Before life existed on Earth, there was just matter, inorganic dead “stuff.” How improbable is it that life arose? And — could it use a different type of chemistry? Using an elegant definition of life (anything that can evolve), chemist Lee Cronin is exploring this question by attempting to create a fully inorganic cell using a “Lego kit” of inorganic molecules — no carbon — that can assemble, replicate and compete. (Recorded at TEDGlobal 2011, July 2011, in Edinburgh, Scotland.

Lee Cronin: Lee Cronin: Oživljavanje materije Prije nego je život postojao na Zemlji, postojala je samo materija, anorganska beživotna “stvar“. Koliko je moguće da je iz toga nastao život? I — je li se mogla koristiti drugačija vrsta kemije? Koristeći elegantnu definiciju života (sve što može evoluirati), kemičar Lee Cronin istražuje to pitanje pokušavajući stvoriti potpuno anorgansku stanicu koristeći ”Lego kit” anorganskih molekula — bez ugljika — koja se može sastavljati, replicirati i nadmetati.
