Scientists Compared Haitian DNA to Dominican DNA — Same Island, Completely Different Ancestors

Two countries. One island smaller than Maine. A border you can drive across in an afternoon. When population geneticists actually ran the numbers, the two populations on either side came back looking less like close cousins and more like two entirely different Caribbean stories. In this video we walk through the real published genetics and the real documented colonial history behind it: 📌 The same 2013 study (PLOS Genetics), same methods, same researchers: Haiti at ~84% African ancestry vs. the Dominican Republic at ~57% European / 35% African / 8% Indigenous 📌 Five independent studies (2010, 2015, 2016, 2023, 2025) all converging on the same Dominican numbers — roughly half European, high 30s to low 40s percent African 📌 The real 1790 population numbers: Santo Domingo (~125,000, under half enslaved) vs. Saint-Domingue (~557,000, close to 90% enslaved) 📌 The Spanish Crown's own documented 18th-century policy — subsidized Canary Islander family migration, specifically to keep Santo Domingo's European population from disappearing 📌 How two revolutions resolved in opposite directions — and why that still shapes both countries' national identity today 📌 The mtDNA Taíno finding this channel has already reported (22% Dominican vs. ~0% Haitian) as a third, independent line of evidence 📌 An honest, necessary note on how this same genetic gap was historically weaponized — including under the Trujillo regime — and why a population average is not a verdict on any individual family Every claim in this video is drawn from published, peer-reviewed genetic research and documented colonial history — not speculation, and not politics. 🔎 Want to know what your own family's documented paper trail actually shows, on either side of this shared island?
