Eukaryotic cells are cells that contain a … WebRather, Eukaryotic genes present in bacterial and archaeal organisms are hypothesized to be from horizontal transfer from an early ancestor of modern eukaryotes. This putative ancestor possessed crucial "starter" genes that enabled increased cellular complexity. This common ancestor, or a relative, eventually led to the evolution of eukaryotes.
