  • More than 50 years ago, Miller performed his groundbreaking experiments that showed that an atmosphere containing methane and ammonia could yield amino acids, the building blocks of proteins. Today, many authors favor a carbon dioxide-rich atmosphere, but such an atmosphere is much less suitable for producing organic molecules. In his Perspective, Chyba highlights the report by Tian et al ., who propose instead that the early atmosphere was carbon dioxide--based but may have contained many… CONTINUE READING
