Here, we first review and synthesize genetic,palaeoclimatological, linguistic and historical data on the peopling of theCongo Basin. While forest fragmentation led to the increased genetic andgeographical divergence of forest foragers, these groups maintained long-distance connectivity. The eventual expansion of Bantu speakers into theCongo Basin provided new opportunities for forging inter-group links, asevidenced by linguistic shifts and historical accounts. Building from ourethnographic work in the northern Republic of the Congo, we show howthese inter-group links between forest forager communities as well astrade relationships with neighbouring farmers facilitate adaptation to eco-regions through knowledge exchange. While researchers tend to emphasizeforager{\textendash}farmer interactions that began in the Iron Age, we argue that foragers{\textquoteright}cultivation of relational wealth with groups across the region played a majorrole in the initial occupation of the Congo Basin and, consequently, in culturalevolution among the ancestors of contemporary peoples.}}, journal = {{Philosophical Transactions of the Royal Society B: Biological Sciences}}, volume = {377}, eid = {20200490}, }
