Answer:
Prokaryotes.
Explanation:
Most of the Eukaryotes most likely to evolve from the Prokaryotes. Prokaryotes are basically unicellular organisms that lack internal membrane-bound structures. So, they do not carry nucleus and generally have a single chromosome. Most of them have a cell wall outside the plasma membrane, which is a thin layer of lipid that completely surrounds the cell. Prokaryotes reproduce by binary fission method.
