Pato criollo: an American domesticate that European shipping turned into a world poultry species, and that Fujian re-domesticated after 1743

The Muscovy duck — pato criollo in Spanish America, Cairina moschata in zoology — was domesticated in Central or South America before any European arrived, and Cabeza de Vaca found Guaraní farmers breeding ducks in quantity. Genome papers of 2021 and 2024 carry it onward: European colonists spread the bird worldwide, a Chinese gazetteer of 1743 records its arrival in Fujian through the Europe–China trade, and in 1996 a French company sold a commercial Muscovy breed back into China.
