Throughout evolutionary history, a common ancestor links various life forms, particularly between Archaea and Eukarya. Eukaryotic cells are characterized by membrane-bound organelles and a nucleus, with groups such as Unikonta and Opisthokonta displaying unique features like a single posterior flagellum.
