Research: North African artifacts and bone marrow made with contemporary archeology materials in East Africa.

Mohamed Sahnouni, a group of scientists led by the National Evolutionary Center (CENIEH), archaeologists, has just published in the journal Science It breaks the humanity's child into a paradigm of what is in East African Africa, based on the archaeological sites found in the Ain Hanech region of Algeria, the oldest in the north of Africa.

For a long time, East Africa has been the origin of early homilies and lithic technologies, which until now has not been widely known about Northern occupations and activities in the northern continent. Two laboratory laboratories in the laboratory and Sahnouni have demonstrated that ancient humans have developed North African stone tools at the present time with the most popular stone instruments in Africa with less than 2.6 million years of age.

Stone artifacts and animal bones are trademarks of stone cuttings, estimated at 2,6 and 1,9 million years old, respectively, found in two levels located in Ain Boucherit (Ain Hanech study area). Paleomagnetism, using Electron Spin Resonance (ESR) and bio-chronology of large mammals, together with archaeological material.

Animal fossils, such as pigs, horses and elephants, have been very ancient sites, paleontologists Jan van der Made, in the National Science National Museum of Madrid, to check branches of Paleomagnetism, the age of the geologist CENIEH, Josep Parés, and ESR, Mathieu Duval At Griffith University.

Oldowan technology

Ain Boucherit's artifacts were also useful in the limestone and local stems and also included faces in choppers, polyhedra and subspheroids, as well as cutting tools used to process animal carcases. These artifacts are Oldowan stone technologies from eastern Africa 2.6-1.9 million, although Ain Boucherit shows subtle variations.

"Ain Boucherit's lithenic industry, Gona and Olduvai, is technologically similar, shows that our ancestors were entering all parts of Africa, not just East Africa. Algerian evidence changes the previous view of Africa's eastern humanity – it was the cradle of African humanity "says Sahnouni, head of the Ain Hanech project.

They are not cheap

Ain Boucherit is one of the archaeological sites in Africa, which marks the bones of stone engraving and bones related to percussion, which show stone tools, that is to say, ancestors use ancient bones and flesh of bones and animal bones of all skeletons. Forcing upper and middle ends, evisceration and defleshing.

Isabel Cáceres, an IPHES tapestry, said that "Ain Boucherit's use of rigorous tools suggests that our ancestors are not cheap. It's not clear whether they were hunted at this time, but the evidence clearly shows that carnivores are competing and have first access to animal carcasses ".

Tool makers

At this time, the most important question is what was found in Algerian stone tools. Hominid remains have not yet been found in North Africa with stone artifacts of the time. In fact, we do not have any facts, and we do not have to document any direct association with the first stone instruments in East Africa.

However, a new Ethiopian discovery of 2,8 million years of Homo's initial presence, and the best candidate for materials from East and North Africa.

Scientists have long thought that hominines and their material cultures emerged in East Africa's Great Rift Valley. Surprisingly, the best known of 7,000 million years ago, and 3.3 million years ago Australopithecus Bahrelghazali were found in Chad, in the Sahara, 3,000 km from the rift valleys of East Africa.

Sileshi Semaw, a CENIEH scientist and author of this paper, were hominid at the age of Lucy (3.2 million years) most likely across the Sahara and later discovered archaeological puzzles as they were found in Algeria, just like East African contemporaries.

"Future research focuses on focusing on Miocene and Plio-Pleistocen deposits, looking for tool-makers and looking for older stone tools," Sahnoun concludes.
