Conditions for the emergence of life on the early Earth

Conditions for the emergence of life on the early Earth

La prestigiosa rivista della Royal Society inglese, Philosophical Transactions of the Royal Society B: Biological Sciences, pubblica un intero fascicolo (oltre 200 pagine) sulle condizioni ambientali che hanno favorito la nascita della vita.
Tutti i temi oggetto di studio sono toccati: il mezzo interstellare incubatore della vita, la drammatica formazione del pianeta, la chimica e il clima terrestre, il mondo primitivo dell'RNA, il mondo prebiotico. Un affascinante e rigoroso viaggio alla scoperta dell'origine della vita sulla terra.
