Ancient Russians and Indians share 54% basic vocabulary overlap. Indo-European languages originated with R1a-Z645 Aryans on Russian Plain 5900 years ago. Yamnaya culture R1b-Z2103 people migrated south to Caucasus and Middle East, not Europe with languages. Fatyanovo culture on Russian Plain carried pure R1a-Z93 linking directly to India. Aryans entered India peacefully, headed higher castes, with 72-95% R1a in Brahmins today. Light-skinned Aryans contrasted dark Dravidians, established caste system. R1a-Z93 spread to Central Asians like Kyrgyz, Uzbeks, Tajiks, Tatars, Bashkirs. Sintashta-Arkaim sites mark Aryan path to India, no Slavic gods there. Slavs descend from R1a-Z280 branch staying on Russian Plain, plus I2a and N1a1. Nazis falsely claimed Aryan status – real Aryans R1a-Z645 from Russian Plain including East Germany. Scandinavians R1a-Z284 stayed north, no trace on Russian Plain refuting Norman theory. R1a-Z93 reached Altai, mixed with Mongloids producing Turkic-speaking Scythians like half of Khakas. R1a entered North China 4000+ years ago – Terracotta Army shows mostly Europoid faces from Aryan warriors. Russians and Indians match 104/111 STR markers, far closer than to Western Europeans with R1b. Indo-European languages spread to Europe only 3000 years ago from Russian Plain Aryans, replacing pre-existing tongues. No R1b in India proves Yamnaya not Aryan bridge to India.
