The Digital Evolution of Human Intelligence started at the Klasies River Mouth Caves, Eastern Cape, South Africa with the development of mandible

Klasies River Mouth Caves are the oldest modern human site, where the fossils of oldest developed mandible were enearthed. The developed mandible is the unique feature of modern linguistic humans. It houses the vocal tract with vowel resonance. The developed mandible is an evidence of acquisition of vowel and vowel accented syllables. In information theories, digital signals are mutually discrete, finite (or shared between information senders and receivers) and one dimensional (like messenger-RNA or sentences). So syllables are digital signals. And, the discovery of the oldest developed mandible at Klasies River Mouth Caves indicates that human intellectual evolution is a digital evolution. The images of caves are used to explain the inside and outside scenary of the caves.
