April 26, 2022, 9:48 PMWASHINGTON - A fresh examination of meteorites that landed in the United States, Canada and Australia is bolstering the notion that such objects may have delivered to Earth early in its history chemical ingredients vital for the advent of life.
Nucleobases are nitrogen-containing compounds crucial in forming DNA's characteristic double-helix structure. "There is still much to learn about the chemical steps that led to the origin of life on Earth - the first self-replicating system," Glavin said. "This research certainly adds to the list of chemical compounds that would have been present in the early Earth's prebiotic soup."The researchers examined material from three meteorites - one that fell in 1950 near the town of Murray in the U.S.
Earth formed roughly 4.5 billion years ago. In its infancy, it was pelted by meteorites, comets and other material from space. The planet's first organisms were primitive microbes in the primordial seas, and the earliest-known fossils are marine microbial specimens dating to roughly 3.5 billion years ago, though there are hints of life in older fossils.
