Captive chimpanzees learn from their mothers to call out to humans, new research suggests. Those chimps raised by their moms were also most likely to use similar calls, from lip-smacking to blowing ...

Scientists have traditionally sought the evolutionary origins of human speech in primate vocalizations. But unlike these primate calls, human speech is produced using movements of the tongue, lips and ...

The oral-facial component of human speech evolved from lip smacking, a friendly back-and-forth gesture performed by primates such as chimpanzees, baboons and macaques. The studies suggest a separate ...
