IndusValleyScriptMayNotRepresentaSpokenLanguage

A multidisciplinary team including researchers from the Tata Institute of Fundamental Research (TIFR) and the University of Washington has presented compelling evidence suggesting that the enigmatic Indus Valley Script, found on seals and artifacts from 2500-1900 BCE, may not represent a spoken language. Through statistical analysis of symbol patterns and comparisons with known linguistic and non-linguistic systems, they found that the script's structure aligns more closely with non-linguistic systems like Near Eastern administrative tokens or medieval heraldry. This challenges the long-held assumption that the approximately 400 distinct symbols constitute a full writing system. The research involved applying computational methods to analyze sign sequences and repetition frequencies, finding a level of regularity inconsistent with typical spoken language scripts. The surprising implication is that the Indus Valley civilization communicated complex information through a sophisticated system of symbols without necessarily encoding speech.
