The early modern human vocal apparatus is generally thought to have been the same as that in present-day humans, as the present-day variation of the FOXP2 gene associated with the neurological prerequisites for speech and language ability seems to have evolved within the last 100,000 years, [124] and the modern human hyoid bone (which supports ...
