Re: Interesting idea - Musical Tuning and Human Biology - today's

Given recent anthropological studies of why Humans 'learnt to speak', the
suggestion is that hominids were great 'howlers' or 'singers', and that
speech is merely a gradual complexification of 'singing'.

Therefore, it seems reasonable that speech should retain elements of
pitches.

Music is older than speech would be my hypothesis based on current thinking.
