Neanderthal theory of Indoeuropeans - стр. 6
Ket people.
Hittites (Khets) created a famous empire on the territory of Asia Minor. Where did they come from? This event is encircled in mystery. The conquerors retained old names of the previous Hatti and even seemingly adopted their culture. How to explain such respect? Pronunciation of Hittites is similar to Kitai, the Russian name for China. Hatti is similar to Yeti. Were Yenissean Kets a very remote spawn of Hittite Empire or maybe both Hatti and Hittites came to Anatolia from South Siberia? The most probable variant is multiple shuttle migrations between these sites.
All these facts make it possible to formulate a hypothesis that what is known as Indoeuropeans was a group of modern humans led by remains of the previous hominids. They had 150 millennia longer human experience, were specifically adapted to northern climate and high mountains so were well suited to form a ruling class over the next generations.
Now let's look how this subgroup evolved further already as a part of Homo Sapiens. The first civilized communities separated into pastoralists and peasants which correspond to hunters and gatherers of Stone Age. Neanderthals were predominantly hunters so they should be linked to the later nomadic herders.

Scythians
There was a large group of such people between the Black Sea and Central Asia. Scythians were Iranian-speaking nomads. Iran has prominent Neanderthal sites too. Neanderthals emerged circa 300000 years ago. Just before this time Caspian Sea was dry. Water level dropped 30 – 50 metres below present. Just 2 lakes remained. Rising sea could prompt large-scale migration of previous hominids. Wide area to the East from Caspian presented excellent conditions for prehistoric hunters. There were abundant game and fresh water. Rocky desert supplied stone tools. Hominids dwelled hundreds of thousands of years there.
At the other side of the sea, landscape was formed by 2 lengthy processes. Sea level substantially oscillated over millennia. Simultaneously, the mountains of the Greater Caucasus rose. This was a lengthy process which began 30 Ma BCE, sharply increased 5 Ma BCE and 2.5 Ma BCE when hominids emerged, and continues into the 3 millennium CE. Elbrus and Kazbek are volcanoes.
Mount Elbrus viewed from the south in Russia.
Elbrus erupted 200 Ka, then 33, 21, 8, 6, 5 Ka ago, even possibly 2 and 1 Ka ago.
Kazbek, 5047 m.
Kazbek erupted 40 Ka ago. Oscillating sea level plus the rise of mountains created terraces. They may be elevated up to 400 m, but Dagestan has many terraces above this. They are artificial and were created for agriculture in the range from 900 to 2400 m above sea level, that is in cold zone. Human agriculture started here in the 3 or 2 millennium BCE, well after Neanderthals. Nevertheless somebody taught humans how to do it.
