"Another lost race theory": who is in the reference panels

SUMMARY"Another lost race theory": who is in the reference panels (Nov 7, 2026; Tito: "Unknown group that doesn't exist while we don't get tested fairly with the correct control / Another lost race theory"). RECORD, the panels: the Human Genome Diversity Project's Americas samples are five groups, Maya, Pima, Colombians, Karitiana and Suruí; 1000 Genomes' Americas panels are Mexican Americans in Los Angeles, Puerto Ricans, Colombians, Peruvians, and African Americans in the Southwest (ASW) and Barbados (ACB), with no US Native nation. No Southeastern nation (Cherokee, Creek, Catawba, Lumbee, Powhatan, the Eastern Shore peoples) and no Indigenous-papered-as-Black community is a "Native American" reference. Black Americans are modeled as African plus European against Yoruba and Utah samples (P823, Coop). RECORD, why the nations hold back: the Havasupai gave blood to Arizona State for a diabetes study (1990–1994, about 400 people); it was used for studies on schizophrenia, inbreeding and migration without consent; settled 2010 ($700,000, samples returned). The Lumbee were told their 1958 samples were for health (P824). RECORD, the old "lost race": in the 1800s, the Mound Builders were said to be a vanished "lost race," not the land's own people, until Cyrus Thomas's Smithsonian report (1894) credited the nations

PATTERNwhen the living descendants aren't sampled, the signal is named a ghost (Population Y, "an unknown group that doesn't exist anymore") instead of looked for in the living, the same move as the Mound Builder myth. TEST, Open (Rule 14, the correct control): sample Southern Black American families with deep local roots (rolls, Accomack, the Carolinas, Louisiana) and Southeastern nations with consent and community control of the data, then run the same Australasian/Population Y statistics and the Tf D1 vs DChi check (P824). If the signal shows up, Population Y isn't lost; it was unsampled
