The RNA World: Solving Life's Chicken-or-Egg Problem
2025-01-16
The 'chicken or the egg' dilemma of life's origin—the interdependence of DNA and proteins—has long puzzled scientists. New research suggests RNA may have played both roles. Early life may have consisted solely of RNA, capable of both storing genetic information and catalyzing chemical reactions, enabling self-replication. This 'RNA world' hypothesis resolves the paradox, offering insights into how life emerged from simple chemistry. Further research focuses on early Earth environments—soda lakes or impact crater lakes—that could have fostered RNA and other building blocks, providing more clues to unlock the mystery of life's origin.
