Wild or domesticated? An ancient DNA approach to canid species identification in South Africa's Western Cape Province

The fragmentary remains typical of archaeological fauna can prove impossible to identify when confronted with closely related sympatric species. In southern Africa domesticated dogs (Canis familiaris) and black-backed jackals (Canis mesomelas) pose just such a problem, rendering difficult an accurate assessment of the timing of arrival of domesticated dogs in the region. Contextual evidence has suggested that canid remains from four Later Stone Age archaeological sites were likely to be domesticated dogs rather than jackals, and were subjected to ancient DNA analyses to determine species. Every tested specimen proved to derive from black-backed jackals. These data provide not only an unexpected window on southern African prehistory, but also highlight the value in applying ancient DNA techniques to archaeological species identification.     

Early North African Cattle Domestication and Its Ecological Setting: A Reassessment

Nearly four decades have passed since an independent North African centre for cattle domestication was first proposed in 1980, based on the Combined Prehistoric Expedition’s work in the Nabta Playa—Bir Kiseiba region of southern Egypt, and the initial rigorous debates between Andrew B. Smith and Fred Wendorf, Romuald Schild and Achilles Gautier. More recently, geneticists have entered the fray with determinations on the spread of haplotypes, and the timing thereof, that extend the scope and increase the complexity of the debate. Here, a new look at the botanical data and a re-analysis of the geology of Bir Kiseiba–Nabta Playa rejects the ecological foundations of the early African domestication model, while a detailed examination of the published osteological and radiometric data from the same area reveals a more nuanced picture than has been recognised to date. These results are placed into context by a wider review of the genetic and other archaeological evidence from the Western Desert of Northeast Africa, where no other cattle remains designated as domesticated have been found. It is concluded that (a) Bos remains from the early Holocene at Nabta Playa—Bir Kiseiba were those of hunted aurochs; (b) domesticated caprines were likely present in Northeast Africa before domesticated cattle; and (c) the domesticated cattle spreading across Northeast and northern Africa, including Nabta Playa—Bir Kiseiba, from the late seventh millennium BC or early sixth millennium BC onwards were descendants of Bos taurus domesticated in the Middle Euphrates area of the Middle East.     

Genetic characterization of an archaeological sheep assemblage from South Africa’s Western Cape

The Neolithic Revolution, constituting a shift from food acquisition to food production, came to Africa as it did to most of the rest of the world: through processes of transmission rather than through de novo innovation. In contrast with other regions the pastoral management of cattle, sheep and goats was widespread in Africa thousands of years before settled agricultural communities or the use of domesticated plants were in evidence ( 46, 35 and 10). We report here the discovery of haplogroup B in the first genetic analysis of an African archaeological sheep assemblage.     

Descent of Iron Age Farmers in Southern Africa During the Last 2000 Years

Ethnographies from southern Africa indicate that patrilineal descent dominates Bantu-language speakers. With great differences in material culture suggesting sociopolitical and economical changes between the earliest farmers that settled in the region in the first millennium AD and those described from ethnographies, it is very likely that descent patterns did not remain static over the course of nearly 2000 years. With major sociopolitical and economical changes, it is not surprising to suggest that other forms of descent also existed amongst farmers of southern Africa in the past. Although it remains ambiguous to establish descent patterns from archaeological remains in the absence of human burials, in this paper I investigate herding practices and the nature of farming as ways to infer descent. The results indicate that at least matrilineal descent was common in southern Africa before the arrival of ancestral Nguni and Sotho-Tswana speakers in the region during the Late Iron Age in the second millennium AD. Other forms of descent were likely present alongside matrilineal descent during the Early and Middle Iron Ages, when widespread evidence for patrilineal descent is absent.     

Domestic Pigs in Africa

The history of African pig breeds is still controversial due to the relative scarcity of archaeological and genetic data clarifying their origins. While these breeds might descend from Near Eastern pigs entering the continent via Egypt during the Neolithic, Africa may be a primary domestication locus for pigs, as indicated for other species such as cattle and donkeys. In this regard, characterisation of the mitochondrial gene pool of African pig breeds has revealed a very low frequency of Near Eastern alleles, suggesting that, if Fertile Crescent pigs played a part in the foundation of African breeds, their genetic signature has been substantially erased. Interestingly, genetic analysis of western and eastern African pig breeds has revealed a strong phylogeographic pattern, with the latter harbouring Far Eastern alleles at high frequencies. This finding is consistent with data obtained for chickens and confirms that livestock was transported in ancient times, from the Far East to Africa as a consequence of the Indian Ocean trade. European colonisation of Africa also involved the introduction of exotic swine breeds such as Iberian pigs. The confluence of the highly divergent European and Far Eastern Sus scrofa gene pools contributed to significantly enrich the genetic reservoir of African swine breeds, favouring their adaptation to environmental conditions that are often harsh. Conservation of this genetic legacy will be of utmost importance to ensure the prosperity of current resource-based subsistence farming systems in Africa.     

The MSA sequence of Diepkloof and the history of southern African Late Pleistocene populations

This paper presents the first multidisciplinary synthesis of the Middle Stone Age sequence of Diepkloof Rock Shelter (South Africa). We explore the main cultural changes that characterized southern African hunter–gatherer societies from OIS 5 to the beginning of OIS 3. We discuss the tempo of these changes, test the current interpretative hypotheses and explore an empirical model to explain the early appearance of symbolic marking within the Pleistocene hunter–gather societies of southern Africa.     

Some Evidence for Seasonality amongst Later Stone Age Hunter-gatherers in Southern Africa

Abstract

The Later Stone Age (LSA) period in Southern Africa is characterised by a succession of cultural traditions. The LSA hunter-gatherer populations were ancestral to the present-day San. They moved around in small bands, within a semi-fixed territory visiting open air and shelter sites to coincide with available resources.

The hunter-gatherers filled every niche in the environment, including the high mountains, deserts and semi-deserts, bush savanna and grass lands. They were well aware of the food sources available in their territories during the course of a year and utilized these opportunities. As winters in southern Africa are relatively mild, and most regions have foods available throughout the year, seasonality is difficult to demonstrate.

In only a few instances there is some evidence for seasonal use or seasonality. Age profiles of seals at Elands Bay Cave suggest short occupation periods during late winter and early spring. In the high mountains of South Africa and Lesotho, where winters are cold and frost and snow common, the faunal and floral remains suggest occupation during late spring, summer and early autumn. Abbot's Cave in the semi-arid central Karoo was used as a hunting lodge during September, relating to the lambing season and migratory behaviour of springbok (Antidorcas marsupialis).     

The History of African Village Chickens: an Archaeological and Molecular Perspective

The history of the introduction and dispersal of village chickens across the African continent is a subject of intense debate and speculation among scholars. Here, we synthesize and summarise the current scientific genetic and nongenetic knowledge in relation to the history of the species on the continent. Sociocultural, linguistic, archaeological and historic data all suggest a complex history for the species in Africa, characterized by multiple maritime and/or terrestrial introductions over time and several dispersal routes towards and within Africa. Molecular genetics information supports these observations and in addition suggests possible Asian centers of origin for African domestic chickens, including South Asia and Island Southeast Asia. However, both sets of data were until now too limited in their geographic scope, both within Africa and in comparison with chickens from Asia, to unravel the history of the species in detail. We anticipate that further continent-wide studies combining archaeological, ancient and/or modern genetic information may shed new insights on the history of the species. These will contribute to a deeper understanding of the history of trading networks and human interactions within Africa and between African and Asian societies, at the root of the development and expansion of African civilizations.     

Intensive hunting during the Iron Age of Southern Africa

Domestic faunal samples from farming sites from southern Africa dating from the Early (～AD 200–900) and Middle (～AD 900–1300) Iron Ages with large faunal samples are typically dominated by sheep/goats (both number of identified specimens and minimum number of individuals for large samples). However, four exceptions to this general pattern from these time periods are Bosutswe, Nqoma (both in Botswana), KwaGandaganda and Mamba (both in KwaZulu-Natal). At these sites, cattle outnumber sheep/goats, which have previously been measured using a Cattle Index. Intensive hunting is investigated at one of these sites, Bosutswe. Using various lines of evidence, including measuring high- vs. low-ranked prey, economic activities, as well as grease extraction and ageing from the most common taxon, plains zebra (Equus quagga), it is suggested that resource depression of wild game likely occurred. This would fit the expectation, based on human behavioural ecology, that as high-ranked game resource diminished over time, more emphasis was placed on cattle herding. The greater emphasis could have influenced descent patterns of people at Bosutswe. By the Late Iron Age (～AD 1300–1820s), cattle dominate most faunal assemblages in southern Africa with large sample sizes, and ethnographic and historical information confirm the central role these animals played in the social, political and economic lives of these farmers.     

DNA analysis of archaeological sheep remains from China

Recent research has thrown considerable light on the history of the domestic sheep, but has not extended to ancient sheep specimens. In the present study, ancient DNA analysis was carried out on eight archaeological sheep remains recovered from Erlitou archaeological site in Henan Province (ca. 2100–1800 B.C.) to explore the genetic structure of ancient sheep and the phylogenetic relationship between ancient and modern sheep. We analyzed the control region sequences and coding regions of mitochondrial DNA from the remains by direct sequencing and restriction fragment length polymorphism analysis, respectively. Our results reveal that all ancient sheep belong to lineage A defined by modern sheep sequences. Phylogenetic analysis shows that neither argali (Ovis ammon) nor urial (Ovis vignei) mtDNA is closely related to Erlitou ancient sheep. In addition, our results suggest that ancient DNA analysis can serve as a powerful tool in tracing prehistoric population movement.     

WEST AFRICAN METALS AND THE ANCIENT MEDITERRANEAN

Summary. Contact between the Mediterranean in Roman or earlier times and the Sahara and lands beyond has commonly been examined from the northern angle with rather negative results (as for instance in Mortimer Wheeler's Rome Beyond the Imperial Frontiers, 1954). Although West African archaeology is still at an infant stage, it is now becoming possible to examine the issue from a southern, inner African, angle. (The multi-volume Cambridge History of Africa, 1975-, and the less consistent UNESCO General History of Africa, 1981-, document some of the progress made in reconstructing the African side of the story.) And, while substantial trans-Saharan communications did not develop till late in the first millennium A. D. with camel-caravans, stimulated especially by the gold of Far-West Africa, evidence is emerging of earlier exploitation of other metals, perhaps connected with horse (and cart?) transport. At two localities on the southern Saharan edge there was copper mining and smelting around the mid-first millennium B.C., with likely trade of the product to the Mediterranean. The case for Nigerian tin at the same period—raised by Taylor in the previous volume of this Journal (1, 317–24)—is less clear, but would make sense in this context. That the same period saw the spread of iron technology in these sub-Saharan regions is doubtless more than coincidence.     

‘The Devil Who Heals’: Fraud and Falsification in the Evangelical Career of John G Lake,Missionary to South Africa 1908–1913

Abstract

An analysis of the missionary career of John G Lake shows that the initial spread of Pentecostalism and Zionism in southern Africa was facilitated by the systematic use of fraud and deception. After having fled from Zion City in America in 1907 to escape popular justice, Lake and his missionary party introduced to South Africa an array of faith healing techniques used by the original Zionist John Alexander Dowie. They used these and other forms of deception to build a unified Zionist/Pentecostal movement. Additionally, they trained a number of influential African Zionists to use these methods – a factor that further contributed to the rapid spread of this new religious movement.     

On the origin of the tree Spondias mombin in Africa

This paper examines evidence for the origin of the tree Spondias mombin in Africa, where it is generally described as introduced from the Neotropics. Based on biogeographical, ecological, and historical evidence, this paper argues that the tree reached Africa via natural, long-distance dispersal, and should be considered an African native plant. The idea that it is introduced appeared in 1868, when it was a scientifically justifiable conclusion reflecting the limitations of nineteenth-century biogeographical knowledge. By the early twentieth century, representing Spondias mombin as a human introduction in Africa was no longer scientifically justifiable because of advances in knowledge of the African flora and plant dispersal ecology. Nonetheless, most authors continued to represent the tree as introduced, in part because such representation was consonant with dominant images of the African environment: (a) that the continent had suffered extensive deforestation in the recent past, and (b) that Africa's flora was depauperate in fruit trees prior to the coming of Europeans. Recent authors continue to describe Spondias mombin as introduced because they have not sufficiently considered the historic contexts of primary and secondary sources on Neotropical plant introductions in Africa. This paper concludes that the human role in creating the African portion of the trans-Atlantic tropical flora has been overemphasized. Natural plant dispersal across the Atlantic may be more frequent than generally accepted.     

Cairo to Cape: The Spread of Metallurgy Through Eastern and Southern Africa

This article traces the beginnings of metallurgy in the eastern half of the African continent, focusing on three regions: (1) Egypt and Nubia; (2) the Great Lakes region of Central and East Africa; and (3) southern Africa. Metallurgy was not practiced much beyond the Nile valley until the first millennium BC, when copper, bronze and iron metallurgy began in Ethiopia and Eritrea, and iron metallurgy in the Great Lakes region. The expansion of agricultural societies carried iron metallurgy south, reaching its southern limit in South Africa by c. 300 cal AD. Copper was also smelted in southern Africa, but its use was restricted to pendants, bracelets, wire and other items of jewelry. In stark contrast to the metallurgical sequence in the Nile Valley, there was no production of tin, lead, gold or silver in central or southern Africa before these regions were linked to the Islamic world system after c. 800 AD.     

The Possible Time and Region of Host Switches of Ancient Malaria Parasites with Reference to the Pliocene–Quaternary Archaeological Sites in Africa

About 96% of all malaria deaths occur in Africa, and the malignant falciparum malaria also originated on the continent. Although falciparum malaria only appeared in the Holocene period, it can be hypothesized that the transfer of malaria parasites from other primates to humans occurred several times in history parallel to human evolution. This study develops the model that examines the possible coexistence of the potential original host apes, human ancestors, and the diverse anopheline mosquito species; and how, where, and when the host switch of these parasites from great apes to humans occurred. Based on the Pliocene-early Pleistocene archaeological sites, it was found that certain early hominin populations could have lived in malaria areas where the anopheline mosquito fauna was moderately diverse. The people of the Lupemban Culture, as well as the Greenlandian and Northgrippian human populations of East and West-Central Africa, lived close to the high diversity of anopheline fauna and the territories of such great apes as Gorilla gorrilla. African mid-Holocene cultures likely came in contact with gorilla populations — the original hosts of Plasmodium falciparum — along the coasts of the Gulf of Guinea and the East African Rift Valley during their migration to southern Africa. The host switch of the ancestor of the falciparum malaria parasite likely occurred in these regions.

     

Ancient DNA for the Archaeologist: The Future of African Research

Ancient DNA analyses are increasingly popular in archaeology. With the exception of Egypt, the African continent has been grossly understudied using these techniques. We review the state of ancient DNA research on Africa, ancient DNA analysis techniques, and common pitfalls in these studies. We provide recommendations for archaeologists interested in collecting and interpreting ancient DNA data.     

The Holocene History of the Southern Lake Chad Basin: Archaeological, Linguistic and Genetic Evidence

Archaeological evidence indicates a complex history of settlement of the southern Lake Chad Basin from the mid-Holocene onward, in parallel with the gradual desiccation of the Sahara and reduction of lake and river systems in the region. These archaeological data can be compared with a growing body of data from historical linguistics and genetics, and the southern Lake Chad Basin is one of few areas in Africa where such comparisons can be undertaken. This paper will serve as a preliminary consideration of some of the issues generated by an initial comparison of archaeological, genetic and linguistic evidence for the peopling of the Lake Chad Basin. It focuses on the contexts of initial encounters between ancestral Nilo-Saharan and Chadic populations south of Lake Megachad and subsequent population expansions and diversifications around the Mandara Mountains.     

Confronting the settler legacy: Indigenisation and transformation in South Africa and Zimbabwe

This article examines attempts to negotiate a perceived residual dominance of settler populations in South Africa and Zimbabwe by means of developmental and cultural policies deemed necessary to restore sovereignty to Africans. Indigenisation has become a preferred strategy for reconstructing post-colonial states in Africa: indigenisation of the economy as part of a Third Chimurenga in Zimbabwe and Black Economic Empowerment in the socio-cultural context of Ubuntu in South Africa. These are issues arising from the regional legacy of contested and uneven transitions to majority rule. Identifying how governments frame the ‘settler problem’, and politicise space in doing so, is crucial for understanding post-colonial politics. Indigenisation in Zimbabwe allows the government to maintain a network of patronage and official rhetoric is highly divisive and exclusivist although couched in terms of reclaiming African values and sovereignty. Revival of Ubuntu as a cultural value system in South Africa facilitates a more positive approach to indigenisation, although Black Economic Empowerment displays elitist tendencies and cultural transformation remains controversial and elusive. The perceived need to anchor policy in socially acceptable (i.e., ostensibly indigenous/traditional) contexts has become a prominent feature of post-colonial politics and is indicative of an indigenous turn in Southern African politics.     

Mitochondrial DNA diversity in a Transbaikalian Xiongnu population

Xiongnu was a confederation of nomadic pastoral tribes (~200 bc–100 ad) that founded the first nomadic empire in Central Asia. According to archeological and historical data, the tribes played a key role in ethnic and cultural processes in Central Asia and adjacent regions of Eurasia. Genetic studies of the Xiongnu published to date have focused on remains from burial grounds in present-day Mongolia, in the southern part of the ancient Xiongnu area. However, paleoanthropological materials from numerous Xiongnu cemeteries and settlements in Transbaikalia (the southern region of Eastern Siberia, Russia) in the northern part of the Xiongnu Empire have not been examined genetically. Here, we analyzed mitochondrial DNA variation in a Transbaikalian Xiongnu population based on ancient DNA obtained from skeletal remains (n = 18) at four burial grounds to complement available Xiongnu genetic diversity data. We detected 16 mitochondrial DNA haplotypes belonging to seven East Eurasian haplogroups (A, B5, C, D4, G2a, N9a, and Y) in the Transbaikalian Xiongnu series. We observed substantial similarity between Transbaikalian and Mongolian Xiongnu series with respect to main haplogroup composition and frequencies. We observed several mitochondrial DNA clusters (N9a, Y, B5, and A16) and 11 of 16 haplotypes that were previously undetected in the Xiongnu gene pool. We also observed high similarity between the Xiongnu and contemporary indigenous populations of eastern Central Asia, particularly Mongolian-speaking groups. These findings extend our knowledge of Xiongnu genetic diversity.     

Identifying regional variability in Middle Stone Age bone technology: The case of Sibudu Cave

A few pieces of worked bone were previously reported from Sibudu, a site from KwaZulu-Natal in South Africa featuring a stratigraphic sequence with pre-Still Bay, Still Bay, Howiesons Poort, post-Howiesons Poort, late and final MSA cultural horizons. Here we describe an expanded collection of worked bones, including twenty-three pieces. Technological and use-wear analysis of these objects, and their comparison with experimental and ethnographic data, reveals that a number of specialised bone tool types (wedges, pièces esquillées, pressure flakers, smoothers, sequentially notched pieces), previously known only from the Upper Palaeolithic and more recent periods, were manufactured and used at least 30,000 years earlier at Sibudu Cave. These tools appear to be part of a local tradition because they are absent at contemporaneous or more recent southern African sites. Variability in Middle Stone Age material culture supports a scenario in which, beyond broad similarities in lithic technology, significant differences between regions, and trends of continuity at a local scale emerge in other aspects of the technical system, and in the symbolic domain. The archaeological record is revealing a complexity that prevents evaluation of the modern character of Middle Stone Age cultures in antinomic terms. We argue here that it is the detailed analysis of cultural variation that will inform us of the non-linear processes at work during this period, and contribute in the long run to explaining how and when crucial cultural innovations became established in human history.
