This is a very interesting read! The key to our present and future is in the past! I highly recommend checking out this article and the topic addressed!
There’s a new paper out in Science – ” The genomic history of the Iberian Peninsula over the past 8000 years” . It discusses genetic change over time, from hunter-gatherer days, the arrival of the Anatolian-ancestry farmers, and the coming of the Indo-Europeans.
The chart above shows what happened when the Indo-Europeans show up. Autosomal steppe ancestry goes from zero to ~40%, but on the Y-chromosome, it goes from zero to 100% over a few hundred years. As quoted in the New York Times, archaeologists ruled out violence as a possible cause. [ ” I cannot say what it is,”said Roberto Risch, an archaeologist from the Autonomous University of Barcelona, who was not involved in the new studies/ But he ruled out wars or massacres as the cause. “It’s not a particularly violent time,”, he said.
Instead, Dr. Risch suspects “a political process” is the explanation. ]
