Four peer-reviewed genetic and morphometric studies, read in full, attach them, and they cut in several directions at once. They credit Iberia with something more specific than transport: a secondary centre of diversity built from a demonstrably limited founding gene pool, where selection produced the non-pungent pepper (67.4% of Iberian accessions non-pungent against 70% pungent in Mexico) that the world now eats as a vegetable and grinds into pimenton. They also take credit away where the evidence takes it away - C. annuum's 78% dominance of duplicated genebank accessions looks like a founder effect rather than agronomic merit; the Portuguese, not the Spanish, drove the pungent pepper into Asia as a cheap substitute for black pepper; and the African link that ties the American and Eurasian pools together is attributed by the authors to the triangular transatlantic slave trade. And it keeps first place where it belongs: at least 10,000 years of Mesoamerican domestication, by a model published in 2024 and still contested, before any European saw the plant.",
