A fossilised fragment of a human jawbone some 180,000 years old has overturned existing theories about the history of mankind.
The fossil was unearthed by a large international research team, led by Israel Hershkovitz from Tel Aviv University in Misliya Cave on Mount Carmel, a coastal mountain range in northern Israel.
This find, which is the earliest fossil of a modern human found outside Africa, suggests that modern humans left the African continent at least 50,000 years earlier than previously believed.
