Gene For Human Speech

Brought to attention by studying an Australian family with a speaking disorder, a gene that influences flexibility of the larynx (thus increasing the structural capability for human speech) is being reported on chromosome 8 (appropriately named the "tospeak" gene). First seen in other primates, it is partially duplicated in humans where its influence is apparently greater, generating speech functionality.  If further verified, will probably be a source for much future study and speculation.
