  "summary": "Acosta's Seville imprint of 1590 describes the guinea pig on the page — a common little animal of the Peruvian sierra called cuy, held for very good eating and offered most frequently in sacrifices — and Alcedo in 1786 records the Spanish name conejo de Indias and a Quito lake named for it. A 2020 study of forty-six ancient mitogenomes dates and routes the animal: a probable second domestication centre in Colombia, Caribbean voyages from about AD 600, one European specimen of 1550–1640.",

Son como conejuelos, y tienen sus madrigueras debaxo de tierra, y en partes ay, donde la tienen toda minada. Son algunos dellos pardos: otros blancos, y diferentes\" (p. 288).

What the page therefore evidences firmly is that the animal was central to Andean ritual life at contact and that a Spanish author printed the fact in 1590; it is not an independent ethnographic record made by someone with no stake in the answer, and the confidence here is set accordingly.",

Twelve ancient Colombian samples, spanning from roughly 5,940–5,670 BC at Checua II to about AD 1600 at El Venado, belong to a distinct species — tentatively Cavia anolaimae — separated from domestic Cavia porcellus by 1,406 mutations, which the authors read as a probable independent centre of domestication in the Colombian highlands. The word \"probable\" is theirs, and the claim rests on mitochondrial data alone, so it is stated here below 0.9.",

The whole European leg of the story rests on one archaeological specimen; the genetics are strong, the sample size for the crossing itself is one.",

The animal that fed Andean households and was offered on Andean altars arrived in the Atlantic world as an exotic pet, and the corpus of colonial-era descriptions read here says nothing about that transition.",

And the archaeological picture has known gaps of its own — preservation at coastal Caribbean and Peruvian sites was poor, and the overall sequencing success rate was sixty-four per cent — so the routes reconstructed above are the routes the surviving DNA supports, not a complete map.",
