Life’s story may stretch further back than scientists once thought. Some genes found in nearly every organism today were already duplicated before all life shared a common ancestor. By tracking these rare genes, researchers can investigate how early cells worked and what features of life emerged first. New computational tools are now helping scientists unlock this hidden chapter of evolution.
