Chimpanzees can SPEAK, scientists claim after reviewing old footage - so, can you tell what these apes are saying?<br /><br />Many scientists believe that the one thing that separates humans from our primate relatives is our unique ability to speak.<br /><br />But new research suggests that the Planet of the Apes could be just around the corner, as scientists claim that chimpanzees can speak after all.<br /><br />An international team of scientists reviewed footage of chimps who had been raised by humans in conditions which would now be considered unethical.<br /><br />Their analysis of this footage, filmed in 1962, suggests that chimpanzees are capable of saying simple human words such as 'mama'.<br /><br />This discovery could overturn old assumptions about ape psychology and show that the neural 'circuitry' of language evolved earlier than previously thought.
