More than 5,000 years agone a nomadic grouping of shepherds rode out of the steppes of eastern Europe to conquer the remainder of the continent. The group, today known every bit the Yamna or Pit Grave culture, brought alongside them an innovative novel technology, wheeled carts, which enabled them to rapidly occupy novel lands. More than 4,500 years ago, the descendants of these people reached the Iberian peninsula together with wiped out the local men, according to novel query yesteryear a squad of international scientists.

The arrival of the hostile invaders inward what is today Espana together with Portugal had “a rapid together with generalized genetic impact,” said Castilian scientist Íñigo Olalde at a conference 2 weeks agone inward Jena, Germany. According to Olalde, during the Bronze Age, the subsequent populations had “40% of their genetic information together with 100% of their Y chromosomes from the migrants.”
Given that children inherit the Y chromosome from their fathers, “this way that the men who arrived had preferential access to local women, in i lawsuit again together with again,” said Reich at the September event.
The study, which analyzed the deoxyribonucleic acid of the remains of 153 individuals dug upwardly inward the Iberian peninsula, is laid upwardly to live on published inward i of the most of import scientific journals inward the world. Neither Reich or Olade, who are both from Harvard University, wanted to offering whatever to a greater extent than details. The geneticist Carles Lalueza-Fox, from the Barcelona Institute of Evolutionary Biology, besides worked on the research.
Three years ago, approximately other query squad led yesteryear Reich suggested that Indo-European languages – the linguistic household unit of measurement to which most European languages belong – developed via the Yamna civilization together with their descendants.
The prehistorian Roberto Risch, from the Autonomous University of Barcelona, told EL PAÍS at the fourth dimension that findings from the La Bastida dig, inward the Castilian southeastern percentage of Murcia, had uncovered “a keen surprise.”
“We realized that the Iberian peninsula was non alone colonized yesteryear the outset Neolithic migration moving ridge 8,000 or 9,000 years agone simply besides yesteryear a after i 4,500 years ago, which brought alongside it a really dissimilar culture,” he said.
War axes together with carts alongside iv wheels tin dismiss live on constitute inward the layers of the world that appointment dorsum 4,500 years. “From together with hence on, close all men’s tombs were filled alongside weaponry, adornments, displays of wealth. The archæology reveals marked signs of a hierarchical lodge that broke alongside the former egalitarianism of the early on Neolithic period,” said Risch.
The findings from Reich’s query squad are besides backed upwardly yesteryear a written report published final twelvemonth yesteryear geneticists Dan Bradley from Trinity College inward Dublin together with Rui Martiniano from Cambridge University. This query squad announced they had discovered a “discontinuity” inward the Y chromosome during the Bronze Age inward the Iberian Peninsula, after studying the deoxyribonucleic acid of the remains of xiv people constitute inward archaeological sites inward Portugal.
“In damage of why the Y chromosome was replaced, nosotros could speculate that the populations from the steppes had superior technology, amend weapons together with besides domesticated horses that could convey given them an wages inward war,” says Martiniano.
