A team of scientists led by Mohamed Sahnouni, an archeologist at the National Center for Research on Human Evolution (CENIEH), has just published a newspaper in the magazine Science which is broken by the pattern of cruel Humanity lies in East Africa, based on the archaeological remains found in the Hanech (Algeria) area, the oldest known in northern Africa .
For a long time, East Africa was considered to be the source of the earliest hominins and lithic technology, because so far, very little was known about the possession and first activities of hominin in the north of the continent. It shows decades of field research and laboratory directed by Dr. Sahnouni has shown that ancient hominins have made stone tools in North Africa that are very up-to-date with the earliest known stone tools in East Africa dating to 2.6 million years.
These are artificial stone and animal artefacts that can cut cutting marks by stone tools, with a chronology of 2.4 and 1.9 million years, respectively, found at two levels at Ain Boucherit sites (within the Ain Hanech study area), dated using Paleomagnetism, Resonance Spin Resonance (ESR), and Biocronology of large mammals that have been deposited along with archaeological materials.
Animal fossils such as pigs, horses and elephants, from very ancient sites, have been used by paleontologist Jan van der Made, from the National Museum of Natural Sciences in Madrid, to confirm the ages ; n are produced by Paleomagnetism, obtained by CENIEH Josep Parés, and ESR geochronologist, discovered by Mathieu Duval, Griffith University.
Ain Boucherit artifacts were manufactured from locally available limestone and flint and comprised surfaces that worked in choppers, polyhedra and subpheroids, as well as sharp cutting equipment used to process animal carcasses. These artifacts are typical of Oldowan stone technology known to 2.6-1.9 million age sites in East Africa, although the Ain Boucherit shows subtle variations.
"The Ain Boucherit slippery industry, similar to Gona and Olduvai, shows that our ancestors are campaigning to all corners of Africa, not just East Africa. The evidence of Algeria is changing the opinion Earlier that East Africa was a cruel Humanity. In fact, African crab was really human, "said Ain Hanech's project leader Sahnouni.
Not just artifacts
Ain Boucherit is one of the few archaeological sites in Africa that have provided evidence of bone with associated marks of cutting and placing in place with stone tools, which show it inconceivable that these ancient homininians use meat and marrow from animals of all sizes and skeletal parts, which suggested wearing, evisceration and defining upper extremes and intermediate.
Isabel Cáceres, a taphonomist at the IPHES, said "the effective use of sharp edge gear at Ain Boucherit suggests that our ancestors were not just. It is not clear at the moment that they are getting, but the evidence clearly shows that they successfully compete with carcinifiers and enjoy first access to animal carcasses. "
At the moment, the most important question is who made the stone tools found in Algeria. Hominin is still not found in North Africa that is contemporary with the earliest stone artifacts. As a matter of fact, no viruses have been recorded again in direct contact with the first stone equipment known from East Africa.
However, a recent discovery in Ethiopia has shown that the presence of an early Homo dates to 2.8 million years, most likely the best candidate for the materials from East and North Africa.
Scientists thought a long time that the hominins and their material culture were derived from the Great Rift Valley of East Africa. Surprisingly, the earliest known hominin, has dated to 7.0 million years, and the 3.3 million years Australopithecus bahrelghazali, found in Chad, in the Sahara, 3000 km of the fall valleys in eastern Africa.
As Sileshi Semaw, a scientist at CENIEH and co-author of this paper, said that the homininians who are up to date with Lucy (3.2 million years) are likely to wander over the Sahara, and their descendants may be is responsible for leaving these archaeological puzzles now found in Algeria, which are contemporary contemporaries of East Africa.
"Future research will focus on searching for human fossils in the surrounding Miocene and Plio-Pleistocene deposits, searching for the makers and even older stone equipment," ends Sahnouni.
