Yakutia is where the Eskimo, Aleuts and American Indians come from! This is also where the ruling classes in Korea and Japan came from.
With the recent translation of a good deal of their ancient records (the Sakha "lost writing" BTW) by Russian researchers, everybody now knows who these Sakha/Yakuts are.
There are "other" Saka ~ and today that part of the world is quite diverse having a population composed mostly of white folks of Russian origin.
BTW, unlike all other groups in Japan, the Japanese top nobel families (descended from the Sakha who went to India) have females with breasts ~ just like the statues in India.
Their warrior class must have been interested in the girls!
The Scythians supposedly were identified by a specific ideograph by the ancient Sumerians. Be interesting if it has reindeer antlers in it!
