This study traces the evolution of the signal calls of anthropoid apes and early hominins to the vocalized phonic utterances of speech. Amongst other aspects, the study innovatively discusses: • the isomeric evolution of the signal call by the recording of the signal’s frequency components, • the acoustic origin of the syllable, • the emergence of vowels from an indeterminate, collective vocalized tonal matrix, • the interval and intervalic subdivision as the common trait uniting dance, scalar melody and syllabic-prosodic speech, and • the coevolution of music and speech The website is: Speech-ANaturalHistory.com
