L_2_16 — Genetic Diversity and Inbreeding: Population Health Across History

Genetic diversity — the total amount of genetic variation within a population — is a fundamental determinant of population health, adaptive potential, and long-term survival. The loss of diversity through inbreeding (mat

Africa harbors the greatest human genetic diversity on Earth — a direct consequence of being the continent of human origin, where populations have accumulated genetic variation for ~300,000+ years. Modern African populat

L_2_14 — Sex-Biased Admixture: Patrilocal vs. Matrilocal Migration

One of the most powerful revelations from ancient and modern DNA studies is that human migration, conquest, and admixture are almost never sex-neutral — they are systematically biased toward one sex or the other, produci
