## Extracted Topic Notes

- A linguistic-cultural label Jiang uses for the steppe/Yamnaya peoples whose language family spreads across Europe, Iran, and India. Source refs: `video:predictive-history-jpti2gfywru@transcript:v1#seg-0029`; `video:predictive-history-jpti2gfywru@transcript:v1#seg-0032`
- The common language Jiang says connected the Yamnaya-derived world from Europe through India. Source refs: `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0027`
- A reconstructed lost mother language behind many European, Iranian, and Indian languages. Source refs: `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0003`; `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0004`
- definition: Jiang treats the Yamnaya, steppe peoples, and Proto-Indo-Europeans as overlapping usable names for this lecture’s pastoralist conqueror culture. Source refs: `video:predictive-history-jpti2gfywru@transcript:v1#seg-0029`
- evidence: Linguistic similarities across Indo-European languages and distinct vocabulary for wheels, dairy, horses, and non-farming life are used to infer a common Proto-Indo-European pastoralist culture from the steppes. Source refs: `video:predictive-history-jpti2gfywru@transcript:v1#seg-0033`, `video:predictive-history-jpti2gfywru@transcript:v1#seg-0034`, `video:predictive-history-jpti2gfywru@transcript:v1#seg-0035`
- diagnosis: Jiang reads the Secret History account of Genghis Khan as suspiciously mythic because it follows the same structure as other Proto-Indo-European founding stories. Source refs: `video:predictive-history-mpqzapnjykm@transcript:v1#seg-0017`, `video:predictive-history-mpqzapnjykm@transcript:v1#seg-0018`, `video:predictive-history-mpqzapnjykm@transcript:v1#seg-0020`
- model: The conquest created a shared Proto-Indo-European language and common religion across India, Iran, the steppes, the Near East, and Europe. Source refs: `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0026`, `video:predictive-history-j4htfjwl5d8@transcript:v1#seg-0027`
- evidence: Jiang says Proto-Indo-European is a reconstructed mother language behind European, Iranian, and Indian languages, supported by cognates such as father, mother, and two. Source refs: `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0003`, `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0004`
- model: The reconstructed vocabulary lets Jiang infer four traits of the Proto-Indo-Europeans: wheels, dairy consumption, relatively few agricultural terms, and horse domestication. Source refs: `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0005`, `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0006`, `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0007`
- evidence: Because wheel vocabulary belongs to Proto-Indo-European and wheels appear archaeologically around 3500 BCE, Jiang dates the first speakers after the invention of the wheel. Source refs: `video:predictive-history-rat-zudjhrm@transcript:v1#seg-0009`
