This ghost lineage remained uncharacterized until now, and after further analysis, it was determined to be unrelated to other lineages from the region. The remains, which once belonged to a woman who had been buried with her knees to her chin, had a secret—her 7,100-year-old bones deepened the mystery of a ghost lineage in Tibet’s past. When exactly this lineage diverged from other East Asian lineages is unknown, but it diverged deeply, and is ancestral to Tibet. However, this ancestry are unrelated to the ghost lineage. The ghost lineage took its secrets to the grave, and for now—even after the excavations—it seems to be keeping them there.
