15cm Taller Tracing Europe s Strangest Genetic Pattern

Why is there nearly a 15cm height difference between the Dutch and Sardinians — two populations that both call themselves European? The answer isn't nutrition. It's written into ancient DNA, and it goes back over 5,000 years.
In this video, we trace the genetic history of the European height gap — from the Neolithic farmers who first settled the continent, to the Yamnaya pastoralists who swept in from the Eurasian steppe and changed everything. Country by country, the same pattern plays out: more Steppe ancestry, taller population. Less Steppe ancestry, shorter. The map doesn't lie.
