Story summary

Geneticist David Reich reveals that ancient DNA analysis shows human history is marked by migration and mixing.
Modern humans exhibit lower genetic diversity, with notable interbreeding with Neanderthals and Denisovans.
Reich's team has published 114 papers on human origins but faces funding uncertainty due to a $2.7 billion cut in federal grants to Harvard.
A federal judge deemed the funding cuts illegal, but the government plans to appeal.
