When did humans start talking?

Human language probably started to develop around 100,000 years ago. Before then, human jaws, mouths and voice boxes were the wrong shape to form words. Some scientists think that all human languages arose from a common language spoken by our ancestors in Africa. There are over 5000 different languages in the world today, although over 90 per cent of these are nearly extinct.
