Similarly, cultural changes are tracked analyzing the evidence of human behavior obtained from the study of several bone and lithic assemblages from these three sites. At least three periods with different cultural features, involving technology, subsistence and behavior, are determined from the available evidence. The first two periods correspond to the Mode 1 tech- nology and Homo antecessor: the first is dated around 1.2 to 1.0 Ma and reflects opportunistic behavior both in technology and subsistence. The second period is around 800 kyr BP. Mode 1 technology is still maintained, but subsistence strategies include systematic hunting and the use of base camps. The third period is dated between 500 ka and 200 ka and corresponds to the Mode 2 technology and the acquisition of directional hunting and other organizational strategies by Homo heidelbergensis. A transition from Mode 2 to Mode 3 seems to appear at the end of this time-range, and may reflect the early phases of a fourth cultural change. With regard to the environment, our main conclusion is that there was an absence of extremely harsh conditions at Atapuerca throughout this time period. The presence of Mediterranean taxa was constant and the dominant landscape was a savannah-like open environment, probably with small forest patches.

In any case, it is not possible to establish clear cut-off points separating entirely different environmental episodes. Our results show no evidence of any relationship between environmental change and cultural change at the Sierra de Atapuerca. Ó 2010 Elsevier Ltd. All rights reserved. 1. Introduction evaluate the possible existence of correlations between cultural and environmental changes. The time period from the late Early Pleistocene to the end of the Middle Pleistocene was an era of cyclic climatic changes (Berger, 2. The Trinchera del Ferrocarril sites 1988; Rial, 1999). This period also saw the human settlement of Europe by Homo antecessor,(Carbonell et al., 2008a) and its even- The Sierra de Atapuerca is situated 15 km east of Burgos (Spain) tual substitution in the fossil record by Homo heidelbergensis and contains several archaeological and palaeontological sites (Arsuaga et al., 1997). From a cultural point of view, this period also dating from the Early Pleistocene to the Holocene (Arsuaga et al., records the appearance in Europe of Mode 1 and Mode 2 techno- 1997; Carbonell et al., 1999b,c, 2008a, Carretero et al., 2008; logical complexes, and even the transition to Mode 3.

Within the Sierra de Technological Modes were defined by Clark in 1968 (Clarke, Atapuerca, the Trinchera del Ferrocarril includes three sites: Sima 1968). They provide a general framework to define the similarities del Elefante, Gran Dolina and Galería (Fig. 1).

As a summarized by Foley and Mirazon Lahr ping their entire stratigraphic sequences at Gran Dolina and Galería, (2003, pp 114) “Mode 1, comprising the Oldowan and Asian Pebble Tool and Chopping Tool Traditions, constituted the simplest mode of production, the striking of a flake off a core. The number of flakes could vary, but what held this system of production together was . the simple platforms and lack of preparation involved. ( ). Mode 2 Atapuerca . fi saw the development of two elements ( ). The rst of these was the Burgos ability to strike off relatively large flakes (.) suitable for a greater amount of invasive retouch. (.). The result was the bifacial tradition Madrid that is represented by the Acheulean and its variants. Mode 3 Portugal represents a major shift in the output of lithic production, although Spain it shares with Mode 2 elements of the way tools are produced. The key difference is that the core is prepared (.). The outcome is a much more diverse set of finished tools, and hence a greater potential for variability and a greater emphasis on smaller items.” (For an extensive explanation, see Foley and Mirazon Lahr, 2003). We should clarify that preparation of cores already occurred during Mode 2, but it was during Mode 3 that this preparation developed, acquired complexity and became generalized. The Sierra de Atapuerca includes several archaeological and Gran Dolina T paleontological sites with a record of all these environmental r in c and cultural events at a local scale. Sima del Elefante, Gran Dolina h Galería e r and Galería, three sites located in the Trinchera del Ferrocarril a d (Railway Trench), provide evidence of both environmental (macro e l and microvertebrates and/or pollen remains) and cultural (stone F e tools and/or modified bones) changes for the 1.2 to 0.2 Ma period. r r o In addition, these three sites have yielded human fossils (Bermúdez c a r de Castro and Rosas, 1992; Carbonell et al., 1995, 2008a). Conse- r i l quently, the sites in the Atapuerca Trinchera del Ferrocarril provide Sima del Elefante a unique opportunity to track the environmental and cultural changes in an European locality over a one million-year period covering several climatic cycles, and recording different techno- logical complexes from Mode 1 to the transition to Mode 3. A traditional premise states that environmental changes drive faunal and cultural evolution, suggesting that the emergence of technology is a result of environmental changes that led the African 42º 21’N 1025102 m. forest landscapes to contract and the savannas to develop between 100010 2.8 and 2.5 Ma (De Menocal, 1995; Vrba et al., 1995).
