Proto-cuneiform’s evolution: Uruk V featured 47 signs—39 numeric (83%) and 8 ideographic (17%). By Uruk III, roughly 150–350 years later, its 838-sign repertoire included 63 numeric signs (8%) and 733 ideographic signs (87%). The change marks a rapid transition from counting to symbolic language representation. Full cuneiform writing of Sumerian followed within about 1,000 years.
