RNA World is a hypothesis that one of the first stages of Abiogenesis was dominated by RNAs.
- Miller–Urey experiment shows how amino acids and nucleobases can naturally form from inorganic components.
- RNAs could form at random from available nucleobases.
- RNAs that were more stable survived for longer.
- RNA can store and replicate genetic information.
- Ribozyme (RNA enzymes) can start or accelerate reactions that are critical for life.
- Ribosome (one of the most critical component of cells) is primarily RNA.
- Sugars (including ribose), amino acids, and nucleobases were detected in asteroids
