Africa’s State of Development is Simple:
… (a) African geography is (most) heavily affected by climate variations over the millennia and epochs, causing a north-south back-and-forth of habitable lands.
…(b) Africa’s horrific disease gradient requires rapid maturity, and it’s fauna is hard to domesticate.
…(c) Africa’s population coverage (not density) prohibited isolation and speciation.
…(d) The absence of cold weather prohibited close-quarters domestication syndrome.
…(e) Even so, Africa, due to the desert and waters all around, is effectively isolated, and has a narrow east-west green belt, is huge, and has few useful rivers for east-west trade, so africa was too far from trade routes.
…(e) even such, the new generation of subraces of africans (especially the Bantu) nearly replaced the old africans (Kho-San) as thoroughly as homo sapiens replaced older species across the world, and even how Europeans and Siberian Americans repeatedly replaced previous generations in those territories.

Africa is backward because it’s an early generation with lower selection pressure for domestication syndrome maintaining a lower IQ (the result of neoteny ), compounded by disease gradient and geography.

They’re doing just fine now. They need another century or two and they’ll be just fine.
