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.

The identification of different prehistoric activity areas and Neanderthal behavior is one of the main research goals at the Abric Romaní site, which is a well‐preserved and microstratified Mousterian archaeological site. A conspicuous occupation surface excavated in level N yielded a remarkably preserved set of aligned combustion activity areas in the inner zone of the living surface. This set of combustion activity areas suggests analogy with sleeping‐and‐resting activity areas of modern foragers. Multidisciplinary analyses suggest (1) diachronic occupation and (2) similar use of the inner zone of the living floor. The sleeping area comprises five combustion activity areas, spaced at approximately 1 m distance from each other. A large wood imprint of travertine was found near the inner zone, suggesting an architectural remain of a prehistoric dwelling. Descriptions of archaic human sleeping activity areas are very few in Paleolithic archaeology. This identification is a proxy for estimating the number of individuals of Mousterian groups that occupied the Abric Romaní rock shelter around 55 kyr BP.

Human cannibalism is currently recorded in abundant archaeological assemblages of different chronologies. The TD6 level of Gran Dolina (Sierra de Atapuerca, Burgos), at more than 800 ka, is the oldest case known at present. The analysis of cranial and postcranial remains of Homo antecessor has established the presence of various alterations of anthropic origin (cut marks and bone breakage) related with exploitation of carcasses. The human remains do not show a specific distribution, and they appeared mixed with lithic tools and bones of other taxa. Both nonhuman and human remains show similar evidence of butchering processes. The stratigraphic evidence and the new increment of the collection of remains of Homo antecessor have led us to identify a succession of cannibalism events in a dilated temporal sequence. These data suggest that hunting strategies and human meat consumption were frequent and habitual actions. The numerous evidences of cannibalism, the number of individuals, their age profile, and the archaeostratigraphic distribution suggest that cannibalism in TD6 was nutritional. This practice, accepted and included in their social system, is more ancient cultural cannibalism than has been known until now.

OBJECTIVES In the last years different methodologies have been developed to reconstruct worn teeth. In this article, we propose a new 2-D methodology to reconstruct the worn enamel of lower molars. Our main goals are to reconstruct molars with a high level of accuracy when measuring relevant histological variables and to validate the methodology calculating the errors associated with the measurements. METHODS This methodology is based on polynomial regression equations, and has been validated using two different dental variables: cuspal enamel thickness and crown height of the protoconid. In order to perform the validation process, simulated worn modern human molars were employed. The associated errors of the measurements were also estimated applying methodologies previously proposed by other authors. RESULTS The mean percentage error estimated in reconstructed molars for these two variables in comparison with their own real values is -2.17% for the cuspal enamel thickness of the protoconid and -3.18% for the crown height of the protoconid. This error significantly improves the results of other methodologies, both in the interobserver error and in the accuracy of the measurements. CONCLUSIONS The new methodology based on polynomial regressions can be confidently applied to the reconstruction of cuspal enamel of lower molars, as it improves the accuracy of the measurements and reduces the interobserver error. The present study shows that it is important to validate all methodologies in order to know the associated errors. This new methodology can be easily exportable to other modern human populations, the human fossil record and forensic sciences.
