Kenya National Museums Lukenya Hill Hominid 1 (KNM-LH 1) is a Homo sapiens partial calvaria from site GvJm-22 at Lukenya Hill, Kenya, associated with Later Stone Age (LSA) archaeological deposits. KNM-LH 1 is securely dated to the Late Pleistocene, and samples a time and region important for understanding the origins of modern human diversity. A revised chronology based on 26 accelerator mass spectrometry radiocarbon dates on ostrich eggshells indicates an age range of 23,576–22,887 y B.P. for KNM-LH 1, confirming prior attribution to the Last Glacial Maximum. Additional dates extend the maximum age for archaeological deposits at GvJm-22 to >46,000 y B.P. (>46 kya). These dates are consistent with new analyses identifying both Middle Stone Age and LSA lithic technologies at the site, making GvJm-22 a rare eastern African record of major human behavioral shifts during the Late Pleistocene. Comparative morphometric analyses of the KNM-LH 1 cranium document the temporal and spatial complexity of early modern human morphological variability. Features of cranial shape distinguish KNM-LH 1 and other Middle and Late Pleistocene African fossils from crania of recent Africans and samples from Holocene LSA and European Upper Paleolithic sites.

Core Technology

The Early Middle Stone Age (EMSA) from South Africa occurred, broadly, between 300,000 and 130,000 years ago. This is a crucial phase in the history of Homo sapiens, as genetic and fossil evidence increasingly indicate that the roots of Homo sapiens reach back to this time. The fossil evidence from South Africa from this period is sparse, but the c. 260,000-year-old Homo helmei partial skull from Florisbad is especially significant in understanding modern human origins. A detailed chronological and regional framework for the EMSA is still in progress, but on the available evidence, the earliest EMSA occupations seem to be centered in the interior and northern regions. Transitional entities such as the Fauresmith and Sangoan and the first EMSA without large cutting tools, from Florisbad, are found in these areas. In the EMSA, biface technology as well as bipolar, discoidal, blade, and Levallois technologies were used to manufacture a wide variety of blanks, some of which were retouched into an array of tool types. Before lithic types such as hand-axes and bifacial points can be used as diagnostic criteria to define, for example, the Fauresmith and Pietersburg, further extended technological analyses are needed to determine their production sequences and context. Prepared core or Levallois technology occur frequently, but not always, in the EMSA. Prepared core technology entails careful planning to shape stone nodules geometrically prior to knapping the preformed blanks. EMSA hunters used Levallois and other pointed flakes as armatures in hafted thrusting spears. Levallois and composite tool technology reflect complex problem solving and hierarchical organizational cognitive capabilities. These competencies are also evident in early pigment processing. The clear footprint of the EMSA on the South African landscape indicates that several human groups populated this region during the Middle Pleistocene. It is highly likely that such groups were linked across Africa and that they collectively developed into Homo sapiens.

Abstract Palaeomagnetic data from Klasies River main site Cave 1 (Eastern Cape Province, South Africa) are reported. Natural remanent magnetisation directions obtained from 77 oriented samples were determined by progressive alternating field demagnetisation methodology. Three palaeomagnetic samplings from the Witness Baulk from the Middle Stone Age (MSA) Late Pleistocene White Sand member and the Holocene Later Stone Age (LSA) middens in Cave 1 were dated and analysed to obtain the palaeomagnetic directions recorded in the sediments. Here we provide new optically stimulated luminescence (OSL) dates for the White Sand Member, and new accelerator mass spectrometry (AMS) radiocarbon dates for the LSA midden of areas not previously dated. The palaeomagnetic analysis took into account rock magnetism and directional analysis. The former reveals that the main magnetic carrier was magnetite; the latter shows that characteristic remanent magnetisation of normal and anomalous directions was observed in the lower portion of the White Sand Member and LSA midden. Normal directions correspond to the palaeosecular variation record for South Africa during the Late Pleistocene. On the other hand, the anomalous directions recorded in the LSA midden might represent the likely Sterno-Etrussia geomagnetic field excursion which occurred during the Late Holocene and is observed in other places on the planet. Finally, the directional data obtained are a potential tool for discussing the age of deposits corresponding to those periods.

Social Variation

Many researchers assume that until 10-12,000 years ago, humans lived in small, mobile, relatively egalitarian bands composed mostly of kin. This “nomadic-egalitarian model” informs evolutionary explanations of behavior and our understanding of how contemporary societies differ from those of our evolutionary past. Here, we synthesize research challenging this model and propose an alternative, the diverse histories model, to replace it. We outline the limitations of using recent foragers as models of Late Pleistocene societies and the considerable social variation among foragers commonly considered small-scale, mobile, and egalitarian. We review ethnographic and archaeological findings covering 34 world regions showing that non-agricultural peoples often live in groups that are more sedentary, unequal, large, politically stratified, and capable of large-scale cooperation and resource management than is normally assumed. These characteristics are not restricted to extant Holocene hunter-gatherers but, as suggested by archaeological findings from 27 Middle Stone Age sites, likely characterized societies throughout the Late Pleistocene (until c. 130 ka), if not earlier. These findings have implications for how we understand human psychological adaptations and the broad trajectory of human history.

Wide Range

The Aterian is a North African late Middle Stone Age techno-complex. It is spread from the Atlantic coast in Morocco to the Middle Nile Valley in Sudan and from the Mediterranean hinterland to the Southern Sahara. Chronologically, it covers the period between c. 145,000 years bp and 29,000 bp, spanning across discontinuous, alternating dry (end of MIS 6 and MIS 4) and humid (MIS 5 and MIS 3) climatic phases. Few, but significant human remains indicate that the makers of the Aterian complex belong to early Homo sapiens. Their osteological features show affinities with the early anatomically modern human record in the Levant (Skhul and Qafzeh), suggesting that Aterian groups may have taken part in the initial dispersals out of Africa by Homo sapiens. Toolkits consist of a variety of implements not only made of stone but also of bone (points, spatulas, knives, and retouchers). They include tools that were lacking in earlier or other North African contemporary contexts, namely bifacial foliates, blades, perforators, burins, endscrapers, and particularly tanged pieces. Overemphasis on tanged tools often obscured the complexity of the Aterian, which instead displays a wide range of cultural and behavioral innovations. New mobility patterns and intra-site organization, as well as early symbolism with the use of Nassariidae shells and ochre, corroborate early fully complex behavior by these populations. Given the broad geographic and chronological extension of the Aterian, differences are evident at both local and regional scales. They suggest the development of a flexible and variable techno-complex mirroring considerable adaptive cognitive and behavioral plasticity derived from nonlinear processes. Such diversified behavioral experiments result from multiple and noncumulative trajectories due to different internal and external stimuli but are still part of a single cultural entity.

Although there is a general consensus on African origin of early modern humans, there is disagreement about how and when they dispersed to Eurasia. This paper reviews genetic and Middle Stone Age/Middle Paleolithic archaeological literature from northeast Africa, Arabia, and the Levant to assess the timing and geographic backgrounds of Upper Pleistocene human colonization of Eurasia. At the center of the discussion lies the question of whether eastern Africa alone was the source of Upper Pleistocene human dispersals into Eurasia or were there other loci of human expansions outside of Africa? The reviewed literature hints at two modes of early modern human colonization of Eurasia in the Upper Pleistocene: (i) from multiple Homo sapiens source populations that had entered Arabia, South Asia, and the Levant prior to and soon after the onset of the Last Interglacial (MIS-5), (ii) from a rapid dispersal out of East Africa via the Southern Route (across the Red Sea basin), dating to ~74–60 kya.

Recovered Material

Storage of symbolic information outside the human brain is accepted here as the first undisputed evidence for cultural modernity. In the hunter-gatherer context of the Stone Age this storage could include artwork, rapidly changing artefact styles and organized spatial layout of campsites. Modern human behaviour in this context is distinguished by a symbolic use of space and material culture to define social relationships, including significant groupings based on attributes such as kinship, gender, age or skill. Symbolism maintains, negotiates, legitimizes and transmits such relationships. It is argued here that artefacts are not inherently imbued with symbolism and that modern human culture cannot be automatically inferred from inventories of archaeologically recovered material culture. Evidence for the out-of-brain storage of symbolism in southern African sites first appears in the final phase of the Middle Stone Age at about 40,000 years ago.

AbstractHere we explore variation and similarities in the two best-represented population groups who lived during the Middle Stone Age and Middle Palaeolithic—the Neanderthals and Homo sapiens. Building on approaches such as gene-culture co-evolution, we propose a four-field model to discuss relationships between human cognitive evolution, biology, technology, society, and ecology. We focus on the pre-50-ka phase, because we reason that later admixing between Neanderthals and Homo sapiens in Eurasia may make it difficult to separate them in terms of cognition, or any of the other fields discussed in this paper. Using our model enabled us to highlight similarities in cognition between the two populations in terms of symbolic behaviour and social learning and to identify differences in aspects of technical and social cognition. Dissimilarities in brain-selective gene variants and brain morphology strongly suggest differences in some evolutionary trajectories that would have affected cognition. We therefore suggest that rather than insisting that Neanderthals were cognitively ‘the same’ as Homo sapiens, it may be useful to focus future studies on Neanderthal-specific cognition that may have been well-developed within their specific context at the time.
