ABSTRACT: African societies, particularly Bantu, have structured their kinship systems around matrilineality, a system in which a man’s true children are children of sisters from the same mother. Indeed, in this system, the children of the sister from the same mother are the natural heirs of the uncles. At first glance, the logic of such kinship remains poorly understood, and the rationale is nonexistent. In this narrative review, we demonstrate that African ancestors possessed empirical knowledge (Information acquired by means of observation, experience, or experimentation) of maternal genetic inheritance, which influenced their social organization, inheritance practices, and the transmission of lineages. We find that the African kinship structure fully respects the scientific principles of mitochondrial DNA (mtDNA) inheritance, known to be exclusively mediated through the maternal line. This biological principle, formally established by modern genetics, suggests that African ancestral hereditary knowledge was not due to chance but rather to a deep understanding of the maternal lineage long before the discovery of mtDNA transmission. This article, which integrates anthropological analyses, historical narratives, and genetic research to explore the depth of African knowledge about heredity and kinship, closely parallels modern scientific knowledge about mitochondrial inheritance. Understanding this connection not only highlights the sophistication of indigenous African thought but also challenges the Eurocentric discourse that presents genetics as a recent Western innovation. By critically examining how African societies have structured their kinship systems through models of biological inheritance, this article demonstrates that African ancestral knowledge anticipated modern scientific discoveries. This convergence of anthropology and genetics underscores the need to recognize and value indigenous knowledge as a fundamental element in studying human ancestry and heredity.
