Africa's technological gap is not explained by genetics

Africa's technological gap is not explained by genetics

Why didn't a civilization with writing, hydraulic engineering, and a state apparatus comparable to those of the Mediterranean or the Indus Valley emerge in sub-Saharan Africa? The question is historical, has serious answers, and has been circulating for almost five years without the crudest versions—those that resolve it with the word race—having disappeared. Therein lies the problem: a legitimate question of Africa's technological development turned into an exam on IQ that no one has known how to correct.

What historians say about Africa before European contact

Let's start with the obvious: Egypt is in Africa. Pharaonic civilization, with its granary accounting, its corps of officials, and its hydraulic works, was born on the Nile, not the Rhine. It is argued that the mechanism was always the same: agriculture that alternated good and bad harvests forces storage, storage forces keeping accounts, accounting generates a surplus, and the surplus frees hands for trades that do not produce food.

Anyone who accepts that scheme for Mesopotamia must accept it for the Nile. The variable is not the continent, it is the river basins and population density. The continent is the excuse, not the reason.

Sub-Saharan Africa dragged along very concrete obstacles: fragile soils, the tsetse fly blocking the way to draft livestock, and a picture of endemic diseases that decimated both newborns and work animals. None of that is fixed with an adjective about race.

Why didn't craftsmanship develop in sub-Saharan Africa?

Some argue that the decisive blow was slavery: a territory that for centuries exported its youngest population cannot consolidate a stable artisan class, because there is no one to inherit the trade. The hypothesis has its logic. A continent that sells people does not accumulate workshops; it accumulates social debt.

The objection is reasonable and also appears in the controversy: if the brake were only the slave trade, craftsmanship should have rebounded in the gaps between wars. It did not. The answer gaining weight is less epic and more uncomfortable: extractive institutions that reward capturing rent and punish producing it.

Slavery worked in both directions

One of the most discussed segments is the direction of the traffic. Against the image of Europeans hunting people in Africa, it is replied that it was African tribes that captured other tribes to exchange them for manufactures they did not produce. And a fact rarely shown in movies is added: for centuries, North African corsairs ravaged the southern coast of Europe, kidnapping Europeans to sell them in Maghreb markets.

Both things peine, and the order of magnitude of each is still debated. What no historian maintains is that slavery is a character trait of anyone: it was an industry, with buyers, intermediaries, and profits. And industries respond to incentives, not genetics.

Can the intelligence of a continent be measured?

Here the slippery ground begins. In the controversy, it is stated that the average IQ of the black population is around 60 points, that there is not a single technical-scientific Nobel Prize, and that no African city had two-story dwellings before the arrival of Europeans. These are rotund statements. They are also statements.

The data cited as support has a trick from the start: the table circulating averages the results of nine international studies between 1990 and 2010 and cross-references them with the average income and public spending on education of each country. That is, it measures populations with unequal schooling, unequal nutrition, and unequal healthcare, and then attributes the difference to biology.

The material itself acknowledges the hole: within Africa there are groups with very different physical traits and origins—from the southern Sahara to the Khoisan or the Dinka—and putting them in the same statistical bag is an exercise that no geneticist would sign.

Genetics as a shortcut: Neanderthals and other unsupported hypotheses

A theory circulates according to which populations that interbred with Neanderthals would have gained a few IQ points, and African ones, by not interbreeding, would have fallen behind. Whoever repeats it usually immediately adds that they are only theories and that they have no idea about the matter. It is an honest warning: the hypothesis has no scientific support and does not explain why the development leap occurred in the last century, not in the Paleolithic.

If DNA were the determinant, the industrial takeoff of East Asia after 1960 would be inexplicable without changing theory every three paragraphs. No one has yet proposed a mechanism that works for both things at once.

Biological race, legal race: why the category does not hold

One of the most useful contributions is the one that dismantles the very subject of the question. It is argued that what is classified as "black" in the United States is a legal concept without a uniform biological basis: a dark-skinned Caribbean who speaks Spanish moves to the Hispanic box, while someone with a quarter African ancestry is labeled black if they so request. The label is distributed by administrative convenience.

If the group to be measured is defined by law and not by biology, any conclusion about its average intelligence measures the law, not the head.

And yet, the question remains without a closed answer

The problem of detail remains, the most uncomfortable one: why in specific villages people still carry firewood on their heads and walk miles for water when technology accessible for centuries exists. There, explanations by history, institutions, and capital fall short, and whoever says they have the complete answer is usually selling something.

With this material, the genetic shortcut does not fit. What is missing is a theory of development that also explains why takeoffs arrive late, suddenly, and almost always hand in hand with an institutional change. That work is still pending.
