Old footage of chimps raised by humans confirms the apes can say 'mama' Swedish researchers reviewed footage of chimpanzees raised around humans.
Analysis of this footage suggests apes are capable of saying simple human words.
Discovery could overturn old assumptions about ape psychology and show that the neural 'circuitry' of language evolved earlier than previously thought.
The researchers argue this is clear evidence that chimpanzees do in fact have the jaw-voicebox 'coupling' required to make syllabic speech.
Dr Amos Grunebaum , an American obstetrician and gynaecologist, says language development explodes from between the ages of two and four .
A child's vocabulary, understanding and communication skills flourish at around these ages, he says.
These skills are an essential foundation for how a child interacts with others.
