Final answer:
The appearance of blade technology in African societies is tied to their use of superior weapons-making technology and to the broader adoption of ironworking. This led to significant advancements in agriculture and the rise of powerful Bantu kingdoms that mastered these techniques.
Step-by-step explanation:
The appearance of blade technology in African societies is associated with the appearance of superior weapons-making technology. This technological advance was a part of a much broader set of changes during the Upper Paleolithic, where humans began to construct tools from a diverse array of materials such as antler, ivory, and bone, moving from simple flake tools to more efficient blade tools. The prepared-core technique refined from the Mousterian provided pre-shaped blades that represented a significant leap in tool-making technology.
Blade technology was a hallmark of the blade tool industry and can be linked to the evolution of human civilization in Africa. With the introduction of ironworking, possibly independently developed in Central Africa, significant socio-political and economic changes occurred. Iron tools such as axes and knives allowed for the expansion of agriculture, settlement, and the formation of large and powerful Bantu kingdoms, that mastered both agricultural and ironworking techniques.
The ironworking technology likely disseminated throughout sub-Saharan Africa through the migration of the Bantus, a people skilled in ironworking and agriculture, who spread across the continent from at least 500 BCE. These developments were not isolated technological advances, but were part of a much broader social transformation that saw the rise of powerful state societies on their way to becoming modern nation-states.
