There seems to be an unwarranted presupposition here. There may be fossil evidence for the anatomical POSSIBILITY of speech, but here as elsewhere possibility is a necessary but not sufficient condition for the appearance of the phenomenon. You need to have organs of speech before you can put them to that use - which may well be an exaptation, to use S.J. Gould's term. While it is conceivable that speech may have pushed the evolution of the larynx etc. in this direction, other causes predating speech may have done so as well. So - still no fossil evidence, I'm afraid.
BLOGGER: de Boer would agree that the matter is not settled, but you cannot jump to the exaptation explanation either. The situation is ambiguous but promising.
