The correct sequence starts with single-celled prokaryotes (2), which are the earliest and most primitive forms of life. Next, single-celled eukaryotes (1) evolved, which have a more complex cell structure. Colonial eukaryotes (4) represent a stage where eukaryotic cells started living together in colonies, which eventually led to the evolution of true multicellular organisms (3), like sponges, where cells have different functions.
