Key Insight
Europe's colonization of sub-Saharan Africa, despite Africa being the cradle of human evolution for millions of years, was not due to differences in peoples but to geographical and biogeographical 'accidents.' Europeans benefited from the triple advantage of guns and other technology, widespread literacy, and advanced political organization, all of which historically stemmed from the development of food production. This development was significantly delayed in sub-Saharan Africa compared to Eurasia due to several key factors, including Africa's paucity of domesticable native plant and animal species, its smaller area suitable for indigenous food production, and its predominantly north-south axis.
The scarcity of domesticable animals was particularly pronounced; while Eurasia had species like cows, sheep, goats, horses, and pigs that met domestication criteria, Africa's iconic large wild mammals (e.g., African buffalo, zebra, rhino) proved untamable and undomesticable, even in modern times. This meant African societies lacked the sustained benefits of animal power for agriculture, transport, and warfare that Eurasia enjoyed. Similarly, Africa yielded fewer varieties of indigenous domesticable plants than Eurasia, contributing to a later start in agriculture, potentially thousands of years after the Fertile Crescent. These disparities in biological endowments gave Eurasia a substantial head start in the development of complex societies.
A critical factor was Africa's north-south continental axis, which starkly contrasts with Eurasiaβs east-west orientation. Along a north-south axis, climates, habitats, rainfall patterns, day lengths, and diseases vary greatly, impeding the spread of domesticated crops and animals. For example, Mediterranean winter-rain crops from Egypt could not spread south of the Sudan due to different rain patterns and day lengths, and Sahel summer-rain crops could not grow at the Cape. Livestock faced barriers like the tsetse fly zones, which decimated introduced Eurasian and North African species. This north-south orientation also retarded the spread of technology; pottery, present in the Sudan by 8000 B.C., took nearly 8000 years to reach the Cape, and writing developed in Egypt by 3000 B.C. did not independently arise in most of Africa, thereby fundamentally slowing the pace of societal development across the continent.
