A new ancient DNA study unveils valuable information about the genetic evolution of Southern African populations, highlighting a surprising genetic stability over the past 10,000 years. The research, which analyzed samples from the Oakhurst rock shelter in southern Africa, compared genomes of ancient individuals with those of modern groups like the San and Khoekhoe.
Genetic Questions and Population Evolution in Southern Africa
Researchers analyzed the genomes of 13 individuals who lived between 10,000 and 1,300 years ago, using advanced DNA sequencing technologies to overcome the degradation of genetic material. The goal was to understand how the genetic heritage of these ancient populations evolved and how it relates to today's San and Khoekhoe groups.
Genetic Stability Over Millennia
One of the most surprising findings is that the populations inhabiting southern Africa 10,000 years ago share remarkable genetic similarities with today's San and Khoekhoe. That suggests an impressive genetic continuity, in contrast to regions like Europe and Asia, where large migrations significantly altered the population composition over the centuries.
The research indicates that southern Africa experienced little large-scale migration until about 1,200 years ago when new groups introduced herding, agriculture, and new languages. Before this period, the genetics of local populations remained largely stable.
Cultural and Genetic Interaction with New Groups
The landscape began to change with arriving migrants who brought technologies like herding and agriculture, initiating interactions with local hunter-gatherers around 1,200 years ago. While these interactions caused some genetic changes, the previous genetic foundation remained significant.
Expanding the Historical and Cultural Understanding of Southern African Populations
Despite significant advances, the study faced challenges, such as the limited number of genomes analyzed—only 13 individuals had their DNA successfully sequenced—and adverse environmental conditions that hindered the preservation of ancient DNA, requiring special extraction techniques that may have introduced certain biases. Researchers plan to expand their studies by sequencing more genomes from different areas of Southern Africa to overcome these limitations and broaden the understanding of the region's genetic history.
Additionally, they intend to deepen the analysis of interactions between migrant herders and hunter-gatherers, seeking to reveal more details about genetic and cultural changes over time. These studies aim to illuminate the genetic trajectory of the region's populations and enable a more accurate reconstruction of the migrations and interactions that shaped their genetic diversity.
