The Origins of Early Sapiens Behaviour: Origins Centre, University of the Witwatersrand, Johannesburg

This exhibition showcases the results of archaeological research at three coastal sites in the southern Cape of South Africa: Blombos Cave, Klipdrift Shelter and Klasies River main sites. Part of a long-term programme aiming to make palaeosciences accessible to the public, the exhibition befittingly started more locally, first at Stellenbosch and then at the Iziko South African Museums in Cape Town, before moving to Johannesburg. The exhibition opened at the Origins Centre of the University of the Witwatersrand on 25 November 2021. To those of us who attended the opening, it provided an opportunity to hear from the archaeologists, curators and designers behind the exhibition. The exhibition opened to the public on 27 November.

Lineal Megalithic Rock Scripts as precursors of Iberian and other lineal Mediterranean/Euro African ancient writings: the case of Fuerteventura (Canary Islands, Spain)

Lineal Megalithic/Paleolithic Lineal signs/lines may have a variety of purposes or representations. Some authors have proposed they represent sky, planets and stars and their movements, space/time representations or others, including letters/syllables or symbols/events. Some are painted, other incised; the latter are relatively more common in Megalithic scripts. Man is “writing” or creating handmade figures on stones /rocks and other supports, which sometimes have intentionally been polished since Paleolithic times: at least 70,000 years BP (Blombos Cave, South Africa). Megalithic script is named because it is associated to megalithic structures, although not exclusively. Von Petzinger 40,000 years old “symbols” and/or writing are extended worldwide in Paleolithic caves and other rocks. Man connection was worldwide in Paleolithic times. Canary Islands incise or picketed lineal writing exists with a transcribed and translated meaning collection of signs (Ibero-Guanche or Latin inscriptions and Lybic ones). Also, other African/European/Mediterranean lineal scripts there exist and examples are given in the present paper. Fuerteventura Island contains in addition many small or bigger stones and rocks with these Paleolithic/Megalithic incised lines all over its territory. About timing in which these stones that were incised by man, we are only referring to a kind of stone crafting. However, we do not discard that they were made by man several thousand years BP. Some Paleolithic/Megalithic scripts are mixed with clear Iberian semi-syllabary signs in Fuerteventura and other Canary Islands. They may reflect the evolution of more ancient Megalithic scripts to lineal writings like those detailed in the present paper and others. Finally, writing concept should be redefined whenever more precise data and dating be available.

The role of materiality in numerical cognition

Numerical elaboration and the extension of numbers to non-tangible domains such as time have been linked to cultural complexity in several studies. However, the reasons for this phenomenon remain insufficiently explored. In the present analysis, Material Engagement Theory, an emerging perspective in cognitive archaeology, provides a new perspective from which to reinterpret the cultural nexus in which quantification develops. These insights are then applied to representative Neolithic, Upper Palaeolithic, and Middle Stone Age artifacts used for quantification: clay tokens from Neolithic Mesopotamia, notched tallies from the European Upper Palaeolithic, hand stencils with possible finger-counting patterns as documented at Cosquer and Gargas, and stringed beads from Blombos Cave in South Africa.

Material Scaffolds in Numbers and Time

The present paper develops a framework for interpreting Upper Paleolithic artifacts from an analysis of material complexity, numeration systems, and timekeeping using cultural categorizations (Hayden & Villeneuve, 2011), insights on the emergence of number terms in language (Menninger, 1992), and the astronomy practices of 33 contemporary hunter–gatherer societies (Yale’s Electronic Human Relations Area Files World Cultures database). Key findings: (1) an absence of societies with minimal material complexity and later-stage numeration systems, suggesting that material scaffolding may be important to realizing explicit number concepts, (2) the consistency of material complexity with both early- and later-stage numeration systems, emphasizing that material complexity may precede and inform the development of complexity in numeration systems, (3) the compatibility of astronomical practices with the spectrum of complexity in material culture and numeration systems, suggesting that the awareness of time may precede both, and (4) the increasing quantification of time consistent with greater material and numeration complexity, suggesting the availability of numbers as a cognitive technology may enable the structuring of time. These findings suggest that astronomy originates in the ability to estimate and infer contextual relations among natural phenomena and transitions from these natural associations to material representations and cognitive technologies that mediate conceptual apprehensions of time as a substance that can be quantified. Given that artifacts may act as scaffolds for explicit concepts of numbers and numbers scaffold explicit concepts of time, prehistoric artifacts such as the Blombos Cave beads (ca. 75,000), Abri Blanchard and Cellier artifacts (ca. 28,000), and Taï plaque (ca. 14,000) may represent similar scaffolding and conceptual development in numbers and time. It is proposed that the prehistoric societies making these artifacts possessed, in addition to material complexity, the abilities to express quantities in language and to use material externalization and cognitive technologies. Further, the Abri Blanchard artifact is proposed to represent externalized working memory, a very modern interaction between mind and material culture.

Faunal Exploitation Strategies During the Later Pleistocene in Southern Africa

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.

The 100,000–77,000-Year Old Middle Stone Age Micromammal Sequence from Blombos Cave, South Africa: Local Climatic Stability or a Tale of Predator Bias?

In this paper, we present a case study of the micromammal sequence from Marine Isotope Stage 5 (130,000–71,000 YBP) at Blombos Cave on the southern Cape coast of South Africa. Our analyses of the micromammal assemblage from 100,000 to 76,000 YBP shed light on micromammal taxonomic distributions, local palaeoenvironments, and site formation processes at this renowned Middle Stone Age site. Taphonomic analyses indicate that spotted eagle owls (Bubo africanus) were the main predator species responsible for accumulating the micromammals, but with contributions from barn owls (Tyto alba). In addition, the micromammal bones have been subjected to a range of post-depositional processes, some of which are associated with microbial actions likely resulting from human or animal activities in the cave. We have recorded three species in the archaeological assemblage that do not occur in the Blombos area today. These are the Hottentot golden mole (Amblysomus hottentotus), Duthie’s golden mole (Chlorotalpa duthieae), and Laminate vlei rat (Otomys laminatus). The biodiversity indices based on micromammal species suggest that local vegetation consisted of different habitats that could sustain a diverse small mammal population. During MIS 5c/5b, the diversity of species declined, but there was still a mosaic of vegetation habitats present in the local area. On a larger temporal scale, climate conditions were slightly more humid than at present, and winter rainfall was seemingly greater. The amount of winter rainfall would have been similar to locations currently c. 50–150 km further west of Blombos Cave. However, based on micromammal proxies, there were seemingly no major fluctuations visible in climate or vegetation composition during the entire 24,000-year period. We suggest that the explanation could be multifaceted, two potential factors being predator bias derived from the owls’ preference for generalist micromammal species or an actual reflection of local stable climatic and environmental conditions in the Blombos area.

Mark Making and Human Becoming

This is a paper about mark making and human becoming. I will be asking what do marks do? How do they signify? What role do marks play in human becoming and the evolution of human intelligence? These questions cannot be pursued effectively from the perspective of any single discipline or ontology. Nonetheless, they are questions that archaeology has a great deal to contribute. They are also important questions, if not the least because evidence of early mark making constitutes the favoured archaeological mark of the ‘cognitive’ (in the ‘modern’ representational sense of the word). In this paper I want to argue that the archaeological predilection to see mark making as a potential index of symbolic representation often blind us to other, more basic dimensions of the cognitive life and agency of those marks as material signs. Drawing on enactive cognitive science and Material Engagement Theory I will show that early markings, such as the famous engravings from Blombos cave, are above all the products of kinesthetic dynamics of a non-representational sort that allow humans to engage and discover the semiotic affordances of mark making opening up new possibilities of enactive material signification. I will also indicate some common pitfalls in the way archaeology thinks about the ‘cognitive’ that needs overcome.

Geoarchaeological investigation of occupation deposits in Blombos Cave in South Africa indicate changes in site use and settlement dynamics in the southern Cape during MIS 5b-4

The archaeological assemblage recovered from the Middle Stone Age (MSA) levels in Blombos Cave, South Africa, is central to our understanding of the development of early modern humans. Here, we demonstrate that the cultural and technological innovations inferred from the Blombos Cave MSA record also correlate with significant shifts in site use and occupational intensity. Through a comprehensive geoarchaeological investigation of three MSA occupation phases, we identified distinct diachronic trends in the frequency of visits and the modes of occupation. During the earliest phases (ca. 88–82 ka), humans inhabited the cave for more extended periods, but cave visits were not frequent. During the later phases (ca. 77–72 ka), the cave was more regularly visited but for shorter periods each time. We argue that these changes in local occupational intensity, which also coincide with shifts in vegetation, sea levels, and subsistence, can best be explained by broader changes in hunter-gatherer mobility strategies and occupation patterns. Fundamental changes in regional settlement dynamics during Marine Oxygen Isotope Stages 5b-4 would have significantly affected the nature and frequency of social interaction within and between prehistoric populations living in the southern Cape, a scenario that ultimately may explain some of the social and technological advances that occurred there during this time frame.

Early humans recipe for processing plants foods at Blombos Cave, South Africa (85-82 ka)

We present the results of archaeobotanical research conducted into the plant diet of early modern humans who intermittently occupied Blombos Cave on the southern Cape coast of South Africa during the Middle Stone Age (MSA). Botanical samples were taken from two combustion events in the MSA sequence dated to 85 and 82 kya (kya = thousands of years ago). Analysis of these samples shows charred starchy plants had undergone processing sequences prior to cooking. The plant cells show evidence of having been pounded whilst still fresh and some of these fragments indicate pounded starchy plant food was mixed with pounded seeds prior to cooking. We infer that these samples represent the earliest known example of food processing and mixing in a ‘recipe’ as part of early human foodways. We consider these findings and their role in human evolution in the context of human behavioural modernity.
