Episode notes
Genghis Khan Example Shows Haplogroup Limits
- Luke Smith uses the Genghis Khan example to show Y-chromosome dominance can mislead whole-genome history.
- Y-haplogroups can spread widely while most of the genome remains diverse and transient.
Deep Divergence In Southern African Genomes
- Luke Smith highlights ancient Khoisan divergence estimates of 260–350k years, indicating deep population splits.
- These dates are inconsistent with a single recent origin around 50–100k years ago.
Early Dispersals Reached Arabia And SE Asia
- Luke Smith notes Homo sapiens were in Arabia by ~85,000 years and in Southeast Asia by ~73,000 years.
- Early dispersals occurred well before the conventional 50k 'great leap' timeframe.
