Proto-cuneiform evolved from numeric to ideographic system within 350 years. Uruk 5 (3500-3350 BC) featured 47 signs: 39 numeric (83%) and 8 ideographic (17%) Uruk 3 (3200-3000 BC) featured 838 signs: 63 numeric (13%) and 733 ideographic (87%) Transition from mostly numeric to ideographic notation occurred over 150-350 years

Proto-cuneiform's evolution: Uruk V featured 47 signs (39 numeric/83%, 8 ideographic/17%), but by Uruk IV just 150-300 years later it had shifted dramatically toward ideographic notation. A rapid transition from counting to symbolic language representation.
