Subsequent research has shown possible routes of synthesis; for example, formamide produces all four ribonucleotides and other biological molecules when warmed in the presence of various terrestrial minerals.
Daljnja istraživanja ukazala su na moguće puteve sinteze: formamid proizvodi sva 4 ribonukleotida i druge biološke molekule kada se zagrijava u prisustvu različitih minerala.
