Scientists Mapped Texas DNA — What They Found Wasn't Supposed to Be There!

Texas sells one identity. Cowboys, cattle, the Alamo. Its DNA tells a layered, stranger story. This documentary maps the real genetic landscape of Texas stream by stream, the Anglo and Scots-Irish South, the German Hill Country, and the deep Tejano current that predates statehood, plus the hidden African, Slavic, Czech, and Polish lines most Texans never expected to find. Region by region, surname by surname, here is what consumer DNA tests and ancient genomes actually reveal about Texan blood. SOURCES: Han, Ball et al.
