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.

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.

AbstractIn this brief introduction, we present and contextualise ‘theoretical pathways’ elaborated in this special issue, in terms of understanding humanity from a deep-time perspective. The participating authors discuss a wide range of approaches related to thinking about human endeavour during the Middle Stone Age and Middle Palaeolithic ranging from the constraints of technological niches and Material Engagement Theory to aspects of palaeo-neurology, agent-based models of self-domestication and co-evolutionary model building. Together, the contributions demonstrate that current theoretical approaches that aim to explain deep-time human endeavour require multi-disciplinary approaches, and that for some researchers, the trend is to move away from the symbolic standard or models of sudden mutation. By doing so, each contribution, in its own way, enhances our understanding of ‘being’ or ‘becoming’ human during the time slice between 300,000 and 30,000 years ago. The work represented here makes it increasingly clear that a singular or particular aspect did not ‘give birth’ to Homo sapiens in Africa during the Middle Stone Age and/or in Eurasia during the Middle Palaeolithic. Instead, humanity in all its complexity was probably shaped by a broad range of factors and processes that took place over an extended period.

Sub Saharan

The obligatory use of cooking by the Mousterian occupants of the north temperate zone relaxed the forces of selection maintaining archaic tooth size and led to the reductions that shaped modern human face form from the Middle East to the Atlantic coast. The delay in the spread of cooking techniques accounts for the later onset of dental reduction to the south. The development and use of projectiles in the African Middle Stone Age led to gracilization and the earlier appearance of "modern" post-cranial and reflected cranial form in Africa. The subsequent adoption of the use of projectiles elsewhere was followed by gracilization and the appearance of "modern" post-cranial morphology. The craniofacial form of Cro-Magnon allies it with the living populations of northwestern Europe, specifically with the fringes in Scandinavia and England, but not with the European continent. Qafzeh represents the pattern still found in sub-Saharan Africa, particularly West Africa. Although the craniofacial configuration in both is "modern," the dentition of Qafzeh is archaic in size and form. Qafzeh is a logical representative of the ancestral form for sub-Saharan Africans but not for Cro-Magnon and subsequent Europeans.

This chapter examines what it means to be human, a member of the biological species Homo sapiens. Comparing humans to a wide range of primates, it shows that no other species has a similar social structure, with social groups of varying sizes built around nuclear families. Moreover, it explores how these traits may have been shaped by humans' shared experience with Canis lupus. Humans are indeed unique, but their adaptations emerge from a set of unusual events, and a considerable amount of the history of modern human evolution seems to be influenced by their association with wolves and their dog descendants. The chapter then demonstrates how modern attitudes toward predators result from religious traditions rather than scientific understanding.

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.

The Late Pleistocene in southern Africa shows important developments in human subsistence economies. Zooarchaeological research indicates that early modern humans exploited a wide range of faunal species during the Middle Stone Age. Southern African societies developed flexible animal exploitation strategies that increased their resilience against the backdrop of drastic Pleistocene climatic changes. While megafauna are virtually absent, very large herbivores such as giant buffalo and dangerous prey such as suids were targeted with regularity. The study of faunal remains of such key sites as Border Cave, Blombos Cave, Klasies River, and Sibudu also played an important role in the development of overarching theories of the role of subsistence in the development of modern human behaviors through landmark studies by Richard Klein, Lewis Binford, and Curtis Marean, among others.

New Perspective

It has long been claimed that Homo sapiens is the only species that has language, but only recently has it been recognized that humans also have an unusual pattern of growth and development. Social mammals have two stages of pre-adult development: infancy and juvenility. Humans have two additional prolonged and pronounced life history stages: childhood, an interval of four years extending between infancy and the juvenile period that follows, and adolescence, a stage of about eight years that stretches from juvenility to adulthood. We begin by reviewing the primary biological and linguistic changes occurring in each of the four pre-adult ontogenetic stages in human life history. Then we attempt to trace the evolution of childhood and juvenility in our hominin ancestors. We propose that several different forms of selection applied in infancy and childhood; and that, in adolescence, elaborated vocal behaviors played a role in courtship and intrasexual competition, enhancing fitness and ultimately integrating performative and pragmatic skills with linguistic knowledge in a broad faculty of language. A theoretical consequence of our proposal is that fossil evidence of the uniquely human stages may be used, with other findings, to date the emergence of language. If important aspects of language cannot appear until sexual maturity, as we propose, then a second consequence is that the development of language requires the whole of modern human ontogeny. Our life history model thus offers new ways of investigating, and thinking about, the evolution, development, and ultimately the nature of human language.

Humans are unique, compared with our closest living relatives (chimpanzees) and early fossil hominins, in having an enlarged body size and lower limb joint surfaces in combination with a relatively gracile skeleton (i.e., lower bone mass for our body size). Some analyses have observed that in at least a few anatomical regions modern humans today appear to have relatively low trabecular density, but little is known about how that density varies throughout the human skeleton and across species or how and when the present trabecular patterns emerged over the course of human evolution. Here, we test the hypotheses that (i) recent modern humans have low trabecular density throughout the upper and lower limbs compared with other primate taxa and (ii) the reduction in trabecular density first occurred in early Homo erectus, consistent with the shift toward a modern human locomotor anatomy, or more recently in concert with diaphyseal gracilization in Holocene humans. We used peripheral quantitative CT and microtomography to measure trabecular bone of limb epiphyses (long bone articular ends) in modern humans and chimpanzees and in fossil hominins attributed to Australopithecus africanus, Paranthropus robustus/early Homo from Swartkrans, Homo neanderthalensis, and early Homo sapiens. Results show that only recent modern humans have low trabecular density throughout the limb joints. Extinct hominins, including pre-Holocene Homo sapiens, retain the high levels seen in nonhuman primates. Thus, the low trabecular density of the recent modern human skeleton evolved late in our evolutionary history, potentially resulting from increased sedentism and reliance on technological and cultural innovations.
