A new study on eukaryotic genes suggests the first complex cells resulted from multiple waves of gene transfers between bacteria and archaea, not just a single fusion event. Researchers analyzed simplified genomes across diverse eukaryotic species to identify ancestral genetic functions, finding evidence that early eukaryotes possessed complex internal structures and metabolic systems.
