Scientists Create RNA From Primordial Soup 369
Kristina at Science News writes "The RNA world hypothesis proposed 40 years ago suggested that life on Earth started not with DNA but with RNA. Now a team of scientists bolsters this hypothesis, having assembled RNA in the lab from a mixture that resembles what was likely the primordial soup. 'Until now,' Science News reports, 'scientists couldn't figure out the chemical reactions that created the earliest RNA molecules.' The new work started the RNA assembly chemistry from a different angle than what earlier work had tried."
