The Yamnaya (Aryans) migrated over the Eurasian steppe about 7000 years ago. At the same time, 95% of other male bloodlines - vanished.
The first thought was, violence. That the Yamnaya butchered their way across the continent... But there was no evidence of that scale of violence.
The key knowledge... The Yamnaya were 10-15cm taller and physically larger than the indigenous males in Eurasia, and had more grave goods (wealthier). There was no violence. Simply women preferring taller, stronger and wealthier males to their indigenous shorter weaker ones.
Their women betrayed them. All of them.
Asian, Black and Indian men. If you mix with white people, your women are going to betray you, genociding your entire line.
It has already begun.
