A Texas A&M University team has uncovered a physical mechanism that may help answer one of the major questions concerning the origin of life, “How did the building blocks form?” Scientists have long known that the building blocks of life – amino acids, nucleobases and sugars – were present in the early ocean, but they were very low in concentration. In order for life to emerge, these building blocks needed to be combined and enriched into long-chain macromolecules.
“In the early ocean, those building blocks were present in the environment,” Ugaz said. “They were there, but they were so dilute; there is a question about how they combined...
