You've had modern humans or people who look pretty modern in Africa by 100,000 to 130,000 years ago and that's the fossil evidence behind the recent "Out of Africa" hypothesis, but that they only spread from Africa about 50,000 years ago. What took so long? Why that long lag, 80,000 years?
Any adaptations produced by evolution are useful only in the present, not in some vaguely defined future. So the vocal anatomy and neural circuits needed for language could not have arisen for something that did not yet existline feed character di

(bantuan)Hypoglossal canal size has previously been used to date the origin of human-like speech capabilities to at least 400,000 years ago and to assign modern human vocal abilities to Neandertals. These conclusions are based on the hypothesis that the size of the hypoglossal canal is indicative of speech capabilities.
Hyoid bones are very rare as fossils, as they are not attached to the rest of the skeleton, but one Neanderthal hyoid has been found (Arensburg et al., 1989), very similar to the hyoid of modern Homo sapiens, leading to the conclusion that Neanderthals had a vocal tract similar to ours (Houghton, 1993; Bo¨e, Maeda, & Heim, 1999).
