Episode notes
Evidence Is Biased And Incomplete
- Luke Smith warns that archaeological evidence is biased and incomplete, so absence of evidence is not evidence of absence.
- Relying only on found sites skews narratives about human origins and timelines.
Haplogroups Tell A Narrow Story
- Luke Smith explains uniparental markers (mtDNA and Y-chromosome) trace only single lines and mislead whole-genome history.
- Haplogroups can imply recent origins while hiding broader, older genetic diversity.
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.
