About these windows
Each label is a global chronological window, not a cultural assignment for every region. Every eligible canonical sample in the selected timeframe is used for Oracle, optimized two-way, Monte Carlo V3, and PCA calculations.
Results describe genetic similarity to reference samples, not direct descent, identity, ethnicity, or membership in a historical culture.
