What Is the Origin of the R One Lineage?

About five thousand years ago, there was a massive invasion of brutal horse riding warrior conquerors from the east into europe. They have been called the most brutal, genocidal invaders of all time in human history. The question is, who are these yamnia people? And then there is the question of the step ancestry, which comes into india sot. I i am informed by very reliable and well placed sources that a new paper is going to be published this year by indian scientists. But let's wait for this new paper to come in with lots of more data, which will prove, prove, beyond any doubt, that arwana originates in india.
