Description: 〈p〉East Africa has provided the earliest known evidence for Oldowan stone artifacts and hominin-induced stone tool cutmarks dated to ~2.6 million years (Ma) ago. The ~1.8-million-year-old stone artifacts from Ain Hanech (Algeria) were considered to represent the oldest archaeological materials in North Africa. Here we report older stone artifacts and cutmarked bones excavated from two nearby deposits at Ain Boucherit estimated to ~1.9 Ma ago, and the older to ~2.4 Ma ago. Hence, the Ain Boucherit evidence shows that ancestral hominins inhabited the Mediterranean fringe in northern Africa much earlier than previously thought. The evidence strongly argues for early dispersal of stone tool manufacture and use from East Africa or a possible multiple-origin scenario of stone technology in both East and North Africa.〈/p〉

Description: The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains. Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithic tools and faunal remains bearing traces of hominin processing, in stratigraphic level TE9 at the site of the Sima del Elefante, Atapuerca, Spain. Level TE9 has been dated to the Early Pleistocene (approximately 1.2-1.1 Myr), based on a combination of palaeomagnetism, cosmogenic nuclides and biostratigraphy. The Sima del Elefante site thus emerges as the oldest, most accurately dated record of human occupation in Europe, to our knowledge. The study of the human mandible suggests that the first settlement of Western Europe could be related to an early demographic expansion out of Africa. The new evidence, with previous findings in other Atapuerca sites (level TD6 from Gran Dolina), also suggests that a speciation event occurred in this extreme area of the Eurasian continent during the Early Pleistocene, initiating the hominin lineage represented by the TE9 and TD6 hominins.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carbonell, Eudald -- Bermudez de Castro, Jose M -- Pares, Josep M -- Perez-Gonzalez, Alfredo -- Cuenca-Bescos, Gloria -- Olle, Andreu -- Mosquera, Marina -- Huguet, Rosa -- van der Made, Jan -- Rosas, Antonio -- Sala, Robert -- Vallverdu, Josep -- Garcia, Nuria -- Granger, Darryl E -- Martinon-Torres, Maria -- Rodriguez, Xose P -- Stock, Greg M -- Verges, Josep M -- Allue, Ethel -- Burjachs, Francesc -- Caceres, Isabel -- Canals, Antoni -- Benito, Alfonso -- Diez, Carlos -- Lozano, Marina -- Mateos, Ana -- Navazo, Marta -- Rodriguez, Jesus -- Rosell, Jordi -- Arsuaga, Juan L -- England -- Nature. 2008 Mar 27;452(7186):465-9. doi: 10.1038/nature06815.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut Catala de Paleoecologia Humana i Evolucio Social, Area de Prehistoria, Universitat Rovira i Virgili, Placa Imperial Tarraco 1, 43005 Tarragona, Spain. eudald.carbonell@urv.cat〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/18368116" target="_blank"〉PubMed〈/a〉

Description: Seventeen Middle Pleistocene crania from the Sima de los Huesos site (Atapuerca, Spain) are analyzed, including seven new specimens. This sample makes it possible to thoroughly characterize a Middle Pleistocene hominin paleodeme and to address hypotheses about the origin and evolution of the Neandertals. Using a variety of techniques, the hominin-bearing layer could be reassigned to a period around 430,000 years ago. The sample shows a consistent morphological pattern with derived Neandertal features present in the face and anterior vault, many of which are related to the masticatory apparatus. This suggests that facial modification was the first step in the evolution of the Neandertal lineage, pointing to a mosaic pattern of evolution, with different anatomical and functional modules evolving at different rates.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Arsuaga, J L -- Martinez, I -- Arnold, L J -- Aranburu, A -- Gracia-Tellez, A -- Sharp, W D -- Quam, R M -- Falgueres, C -- Pantoja-Perez, A -- Bischoff, J -- Poza-Rey, E -- Pares, J M -- Carretero, J M -- Demuro, M -- Lorenzo, C -- Sala, N -- Martinon-Torres, M -- Garcia, N -- Alcazar de Velasco, A -- Cuenca-Bescos, G -- Gomez-Olivencia, A -- Moreno, D -- Pablos, A -- Shen, C-C -- Rodriguez, L -- Ortega, A I -- Garcia, R -- Bonmati, A -- Bermudez de Castro, J M -- Carbonell, E -- New York, N.Y. -- Science. 2014 Jun 20;344(6190):1358-63. doi: 10.1126/science.1253958.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Centro Mixto UCM-ISCIII de Evolucion y Comportamiento Humanos, Madrid, Spain.

Description: A paleomagnetic investigation at the Gran Dolina site excavation (Atapuerca, Spain) shows that the sediments containing the recently discovered human occupation were deposited more than 780,000 years ago, near the time of the Matuyama-Brunhes boundary. Forty-one oriented samples were obtained from 22 sites along an 18-meter section of the Gran Dolina karst filling. The lower 16 sites displayed reversed-polarity magnetizations whereas the upper six sites were normal. The reversal spans the hominid finds at stratigraphic level TD6 (the Aurora stratum), and these hominid fossils are therefore the oldest in southern Europe.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Pares, J M -- Perez-Gonzalez, A -- New York, N.Y. -- Science. 1995 Aug 11;269(5225):830-2.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Institut de Ciencias de la Terra Juame Almera, Consejo de Investigaciones Cientificas (CSIC), Barcelona, Spain.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/7638599" target="_blank"〉PubMed〈/a〉
