Research: Old Stone Artifacts and Cutmarked Bones in North Africa Contemporary with Archaeological Materials in East Africa –


A team of scientists led by Mohamed Saean without a archaeologist at the Centro Nacional Investigació Sobre La Evoluci Humana (Senieh), has just published a paper in the magazine Science The breakthrough with the paradigm that the humanism of Humankind lies in Eastern Africa, based on the archaeological remains found in sites in the area of ​​Ahn Hanchech (Algeria), the oldest currently known in the North of Africa.

For a long time, East Africa has been the place of the earliest mummins and lithic technology, since then, it was very little about the former Haminin occupation and activities in the north of the continent. Two decades of field and laboratory research directed by Dr. Sahnouni has shown that anodised haminins have actually made stone tools in North Africa that are close to contemporary with the earliest stone tools in Eastern Africa dated to 2.6 million years.

These are artifacts and animal bone bearing marks of cutting tools, with an estimated chronology of 2,4 and 1,900,000 years, respectively, found in two levels at the sites of Ain Boucherit (in the Hanech study area), which were dated Paleomagnetism, Electron Spin Resonance (ESR), and the Bionronology of large mammals excavated together with the archaeological materials.

Fossils of animals such as pigs, horses and elephants, from their ancient sites, are used by the Padontologist Jan van der Made, of the Museo Nazional de Ciencias Naturales in Madrid, to understand the ages given by Paleomagnetism, obtained by the Seniors Geochonologist Josep Paris, and ESR, found by Mathieu Duval, from Gryphith University.

Oldowan technology

The Artifacts of Authentic Boucherite are manufactured from locally available limestone and flint and include faces worked in choppers, polyhedra and subpersoids, as well as sharp-edged cutting tools used to process animal carcasses. The artifacts are typical of the old-fashioned stone technology known from 2.6-1.9 million-year-old sites in Eastern Africa, though those of aerial bouquet show subtle variations.

"The Lytick Industry of Auter Boucherit, which is technologically similar to Gona and Olduwai, shows that our ancestors are ventured in all corners of Africa, not just East Africa.The evidence of Algeria changes the earlier view that East Africa is the cradle of Humanity, in fact, the whole of Africa was the lust of human rights, "says Sahhona, leader of the Han Hanchet project.

Not just scavengers

Ain Boucherit is one of the few archaeological sites in Africa that has provided evidence of bones with associated marks of cutting and percussion in situ with stone tools that show unmistakable that the ancestral haminins exploited meat and brain of animals of all sizes and skeletal parts Implies skinning, evolution and deflation of upper and lower extremities.

Isabelle Cassers, a Tapponist at the IPHES, noted that "The effective use of sharp-edged tools in a bowl suggests that our ancestors are not just scavengers, it is not clear at the moment they enjoy it, but the evidence clearly shows that They are successfully competing with carnivores and enjoyed first access to animal carcasses. "

The tool-makers

At the moment, the most important question was that the stone tools found in Algeria were made. Hominine remains not yet found in North Africa that are contemporary with the earliest rock artifacts. As a matter of fact, nor have any humanities documented in equal union with the first stone tools known from East Africa.

However, a recent discovery in Ethiopia has shown the presence of early homo dated to 2.8 million years, most likely the best candidate for the materials of East and North Africa.

Scientists have long thought that the Humans and their material culture are born in the Great Riff Valley in Eastern Africa. Surprisingly, the earliest known hominine, dated to 7.0 million years, and the 3.3 million years Australopithecus Bahraghazali, discovered in Chad, in the Sahara, 3000 km from the referred routes in the east of Africa.

As Syyleks Cemiev, a CENIEH-based scientist and a co-author of this paper, explained that the Humans, who were Lucius (3.2 million years), were probably helped by the Sahara, and their offspring would be responsible for Leaving the archaeological puzzles now discovered in Algeria, which are close tonight of East Africa.

"Future research will focus on looking for human fossils in the myocene and pleyo-plisosene deposits, looking for tools and even older stone tools," says Sahhna without.
