38k Western Expansion as Diaspora Core

The Initial Upper Paleolithic (IUP) and a rapid western expansion around 38,000 years ago, not only the earlier ~50k Out‑of‑Africa pulse, may have been the demographic event that most strongly shaped the ancestry of today's non‑African populations. Recasting the ‘diaspora’ around this later western explosion highlights how archaeological horizons and local founder events can dominate continental genetic structure. — If true, this reframes public and scientific narratives about who non‑African peoples descend from, affects interpretation of ancient DNA, and shifts which archaeological periods receive priority in public funding and education.
