Surprise: genetics reveal that humanity used to be ... barbaric

David Reich on how much ancient DNA evidence has overturned so much consensus thinking how ancient cultures spread. "It wasn't peaceful, it wasn't friendly, it wasn't nice. Some of our archaeologist co-authors were just really distressed." ------------ WTF did they expect? Our ancestors were absolute monsters! It took thousands of years of civilization to create societies where the majority of the people are peaceful, cooperative and even quite nice. Maybe we should avoid importing people who are still stuck in barbaric cultures?
