Pre-historic tools and remains of hominids discovered in Malawi's remote northern district of Karonga provides further proof that the area could be the cradle of humankind.

Professor Friedemann Schrenk of the Goethe University in Frankfurt told Reuters News that two students working on the excavation site in September 2009 had discovered prehistoric tools and a tooth of a hominid.

"This latest discovery of prehistoric tools and remains of hominids provides additional proof to the theory that the Great Rift Valley of Africa and perhaps the excavation site near Karonga can be considered the cradle of humankind."
