Iwo-Eleru Skull |
The result suggests that the ancestors of early humans did not die out quickly in Africa, but instead lived alongside their descendants and bred with them until comparatively recently.
The skull, found in the Iwo Eleru cave in Nigeria in 1965, does not look like a modern human. It is longer and flatter, with a strong brow ridge; features closer to a much older skull from Tanzania thought to be around 140,000 years old.
Prof Katerina Harvati from the University of Tuebingen in Germany used new digitizing techniques to capture the surface of the skull in detail. The new technique improved upon the original measurements done with calipers by letting researchers see subtler details about the skull's surface.

"This suggests that human evolution in Africa was more complex... the transition to modern humans was not a straight transition and then a cut-off." Prof Stringer thinks that ancient humans did not die away once they had given rise to modern humans. They may have continued to live alongside their descendants in Africa, perhaps exchanging genes with them, until more recently than had been thought. The researchers say their findings also underscore a real lack of knowledge of human evolution in the region.

That the situation is not simple and is deep and complex is what we would expect. "In my view, it is the field of genetics that will help us most in clarifying matters," he told BBC News. Separate research published earlier this month suggests that genetic mixing between hominid species happened in Africa up to 35,000 years ago.
Microlithic and ceramic industries were developed by savanna pastoralists from at least the 4th millennium BC and were continued by subsequent agricultural communities. The Efik/Ibibio/Annang Efik, Ibibio, and Annang people of a single ancestor of coastal southeastern Nigeria are known to have lived in the area at least 7 thousand years before Christ.
As a matter of fact, concerning the age of iron working in Nigeria, Basil Davidson indicated in his work Africa before the whites [18] that 'four charcoal fragments in the Nok strata were revealed to have dates between 3500, 2000, 900 B.C.and 200 A.D by carbon dating'. The author then continues by giving the following commentary by Bernard Fagg.
Eurocentric for years had led the whole world to believe that "Iron Age" started in Southwest Asia in 1500 B.C.E. However, iron smelting in Lejja is 495 older than that done in Asia, 1,045 years older than China's Iron Age, and 695 years younger than the Egyptian Pyramids. The team visited various tourist sites in Enugu State including the Institute for African Studies, University of Nigeria, Nsukka (UNN), which led an excursion trip to the Prehistoric Iron smelting site in Lejja in Nsukka.
The Lejja visit proved to be a most auspicious event, for it exposed the visitors to the world’s oldest iron smelting technology.
