The earliest evidence anywhere for the processing of cotton comes from what is now Sudan. It is indirect. No fabric survives from that depth, but the spindle whorls used to spin thread do, and they turn up at sites of the Khartoum culture with calibrated dates in the sixth millennium BCE. Each has the flat round form characteristic of African whorls. That puts Sudanese spinning about a thousand years ahead of the oldest securely dated Indian cotton, and one to two thousand years ahead of the oldest American cotton, from Peru. Ceramics: African first. Iron smelting: African first. Cotton processing: African first. Past a certain point a run of results stops reading as coincidence and starts reading as the technological record of a continent whose peoples were among the most inventive in the ancient world. People at Khartoum were spinning thread eight thousand years ago, in a period the standard curriculum passes over in silence.

Loom weaving is the mechanical line of technological descent, and cotton is where it shows most clearly at a global scale. The machine looms of modern industry evolved from methods that begin in the middle of the Holocene. People invented cotton weaving independently in at least three parts of the world and possibly four. The proof lies in the plants. Each set of inventors domesticated a cotton species native to their own region: Gossypium barbadense in Peru, Gossypium hirsutum in Central America and Mexico, and across India and Africa the two species Gossypium herbaceum and Gossypium arboreum. Nobody was carrying seed between these regions. The pattern is the one that already holds for ceramics and for metallurgy. Communities far apart, with no contact, set out on the same trajectory of invention thousands of years ago and arrived at the same transformative technology by their own routes, working with whatever grew where they lived.
