For decades, chemists have tested theories for how life began on Earth. One hypothesis has caught the scientific imagination for years: RNA World. This theory proposes that prebiotic molecules joined up early on to form RNA, the molecules that carry instructions from DNA in organisms today. RNA World posits that once RNA formed on Earth, it began replicating itself and later gave rise to molecul
