What took so long? Why that long lag, 80,000 years?”

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)."
