RNA evolution

RNA evolution refers to the changes in RNA molecules over time within organisms. These changes occur through mutations—random alterations in the RNA sequence—that can affect how the molecule functions. Some mutations are beneficial and become more common, while others are neutral or harmful and fade away. This process drives diversity in biological functions, influences how organisms adapt, and helps explain the origins of life. Studying RNA evolution helps scientists understand molecular development, disease mechanisms, and the history of life on Earth.
