Until recently, it was thought that homo sapiens, from whom we are directly descended, began in Africa, about 200,000 years ago.
Recently, discoveries of human remains in China and Spain have hurt the 'Out of Africa' theory.
On 28 December 2010, we read of the discovery, in Israel, of human remains that are 400,000 years old.
(Did first humans come out of Middle East.)
Archeologists found eight human-like teeth, and various artefacts, in a cave near Israel's main airport.
They said the remains found in the Qesem cave suggest the making of flint blades, the use of fire and the sharing of food.
The findings have been published in the American Journal of Physical Anthropology.
