Abstract

Ancient DNA (aDNA) analysis was employed to obtain information on the population relationships of the two Thulamela individuals (AD 1400-1700) and six other skeletons from various archaeological sites of the southern African Iron Age – Tuli (Botswana), Nwanetsi, Makgope, Happy Rest and Stayt. Although sequences were short, it seems that the Thulamela female aligns somewhat more with eastern populations as opposed to the male who aligns more with western groups. This result is not surprising given that the two individuals were buried at the same site but their burials were hundreds of years apart. It was also possible to identify genetic links between the Iron Age individuals and modern southern African populations (e.g. some of the skeletons assessed showed maternal genetic similarities to present-day Sotho/Tswana groups) and to separate the samples into at least two genetic groups. Poor quality and quantity of DNA meant that only haplogroups, not subhaplogroups, of the individuals could be traced.

Abstract

Current potters in Manaledi village in the Tswapong Hills of Botswana aver that they and their ancestors for five generations have made pottery exclusively with clay from nearby sources. We begin with an examination of Manaledi and its clay mine to uncover current dialectics between village, landscape, clay, potters, and ancestors. Archaeological sherds found around the village and clay sources document occupation by makers of Early Iron Age (ca. AD 500-750), Middle Iron Age (ca. AD 750-1050), Late Iron Age (ca. AD 1420-1800), and 18th-20th century wares related to current Manaledi pottery. The proximity of archaeological deposits, clay sources, and village made it possible to conduct simultaneously what might otherwise be considered three separate projects. As a consequence, we are able to document that Manaledi clays have been used to make pottery for some 1500 years and to consider long-standing constraints on potting this implies.

Abstract

Terrace farming flourished in Bokoni from the sixteenth century CE onwards. Bokoni farmers’ resilience strategies, however, were severely tested during the third occupation phase (approx. 1780 to 1840 CE), when the mfecane destabilised the region. In order to reflect on the environmental conditions Bokoni farmers faced in this period the stable carbon isotope proxy rainfall records from Prunus africana and Pittosporum viridiflorum specimens that grew on the Buffelskloof site were studied. Because the Buffelskloof records postdate the occupation, the records are compared with a 1000-year Adansonia digitata rainfall proxy record from the Pafuri region. Deviations between the two are attributed to the juvenile effect, and when these are discounted there is a significant correlation between local and regional rainfall records. This suggests common large-scale synoptic forcing underlies regional rainfall variability, and the decadal-scale variability in the Adansonia digitata records indicates extremely dry conditions in the 1780 to 1840 CE period.

Abstract

Until recently archaeological evidence predating the historically known Kingdom of Dahomey in southern Bénin has been next to non-existent. The situation changed when deep and long drainage channels were dug into the fertile soils at the modern town of Bohicon. In the sides of these channels, rich cultural remains appeared, confirming the assumption that high rates of soil accumulation have caused low archaeological visibility in the forest/former forest belt of West Africa. Geophysical mapping and extensive excavations have revealed two large settlements of 500-600 hectares each, partly overlapping but separated by 2000 years. This paper presents both sites – Sodohomé 1, the earliest site encountered so far in southern Bénin, and Sodohomé 2 (or Sodohomé-Bohicon) which dates to AD 900-1150/1220. Although the first has produced some remarkable results, for instance, an iron spearhead that is the oldest securely dated non-meteoritic iron object in Africa known so far, the focus is on the latter site where evidence demonstrates the existence of a true town with craft specialisation, industrial-scale iron production, long-distance trade and wide communication networks.
