water enriched with urea would have been an efficient source for the formation of noncanonical pyrimidines. In the presence of aldose sugars, bases from these pools could react with the sugars through spontaneous glycosylation, ultimately concentrating de novo nucleosides through aggregation. We demonstrate how such a setting could lead to noncanonical nucleosides on a prebiotic Earth.
