Story

The narrative of this ancient life

The Late Stone Age (LSA) in Tanzania, particularly in the Kisese region, is a fascinating period that highlights the complex interplay of environment, technology, and culture in Sub-Saharan Africa. This era roughly spans from about 50,000 to 10,000 years ago, bridging the end of the Middle Stone Age and the advent of more settled agricultural societies.

Environmental Context

During the Late Stone Age, the climate in what is now Tanzania experienced significant fluctuations, with periods of increased rainfall followed by arid phases. These climatic changes influenced the types of vegetation available and the distribution of wildlife, which in turn affected human subsistence and settlements. The landscape was a mosaic of grasslands, woodlands, and savannas, allowing for diverse ecological niches that supported a variety of plant and animal life.

Archaeological Sites and Discoveries

One of the most well-known sites in Tanzania from this period is Kisese II, a rock shelter in the Kondoa District. Excavations have revealed a wealth of information about LSA cultures, including tools, artwork, and evidence of subsistence practices.

The LSA toolkit in this region was characterized by microlithic technology. People crafted small, precise stone tools that were often hafted onto wooden or bone shafts to make composite tools. These tools were used for hunting, processing plant materials, and crafting other implements.

Subsistence and Lifestyle

The inhabitants of Late Stone Age Tanzania were primarily hunter-gatherers, exploiting the rich biodiversity of their environment. The tools and remains found at Kisese and similar sites indicate a diet that included a wide array of mammals, birds, fish, and plant resources. The adaptation to both terrestrial and aquatic resources reflects a flexible survival strategy that could adjust to changing environmental conditions.

The presence of grindstones and other plant processing tools suggests that plant foods played a significant role in the diet. This included seeds, nuts, and tubers. The variety and sophistication of these tools imply a deep knowledge of local flora and a capacity for planning and storage.

Social and Cultural Aspects

The Late Stone Age was a period of significant social and cultural development. Evidence of symbolic behavior has been uncovered, most notably in the form of rock art. The rock shelters in the Kondoa area, including those at Kisese, contain paintings that depict humans, animals, and abstract patterns. These artworks suggest a community with a rich symbolic life and possibly complex spiritual beliefs or rituals.

The presence of personal adornments, such as beads made from ostrich eggshells and bone, indicates a culture with a sense of identity and social structures. Trade or exchange networks might have been in place, facilitated by shared cultural practices across the region.

Technological Innovations

The LSA period saw several technological advances. The use of microliths, as mentioned earlier, allowed for more efficient hunting and processing of natural resources. The development of these tools is an indication of the cognitive capabilities of LSA peoples, reflecting innovation and adaptation.

Fire also played an essential role, not only for cooking and warmth but as a tool for landscape management, aiding in hunting and encouraging the growth of certain plant species.

Conclusion

The Late Stone Age in Tanzania, exemplified by sites like Kisese, reveals a dynamic period of human history marked by adaptation and innovation. The people of this time were adept at manipulating their environment and had complex social structures, as seen in their art and technology. These cultures laid important foundations that would influence subsequent periods, including the advent of more settled agricultural societies. Understanding the LSA in Tanzania provides crucial insights into the broader human story, particularly regarding the development and spread of modern human behaviors in Africa.

Ancient DNA and deep population structure in sub-Saharan African foragers

Authors Lipson M, Sawchuk EA, Thompson JC
Abstract

Multiple lines of genetic and archaeological evidence suggest that there were major demographic changes in the terminal Late Pleistocene epoch and early Holocene epoch of sub-Saharan Africa1-4. Inferences about this period are challenging to make because demographic shifts in the past 5,000 years have obscured the structures of more ancient populations3,5. Here we present genome-wide ancient DNA data for six individuals from eastern and south-central Africa spanning the past approximately 18,000 years (doubling the time depth of sub-Saharan African ancient DNA), increase the data quality for 15 previously published ancient individuals and analyse these alongside data from 13 other published ancient individuals. The ancestry of the individuals in our study area can be modelled as a geographically structured mixture of three highly divergent source populations, probably reflecting Pleistocene interactions around 80-20 thousand years ago, including deeply diverged eastern and southern African lineages, plus a previously unappreciated ubiquitous distribution of ancestry that occurs in highest proportion today in central African rainforest hunter-gatherers. Once established, this structure remained highly stable, with limited long-range gene flow. These results provide a new line of genetic evidence in support of hypotheses that have emerged from archaeological analyses but remain contested, suggesting increasing regionalization at the end of the Pleistocene epoch.
