A study was recently published in the Nature magazine where different changes are shown in prehistoric European populations. This is demonstrated by the genome analysis carried out on 51 individuals that colonized the European continent.
Regarding these people, it must be taken into account that the last Ice Age was about 100,000 years ago and ended about 12,000 years ago in Europe, at which time Homo sapiens arrived from Africa, which caused the Neanderthals to gradually disappear.
This class of hominids set foot on continental soil some 45,000 yearsAlthough some remains have been studied, only the genetic makeup of four of them was known, but now, after the studies, there is new data that reveals important changes that are linked to the end of the last Ice Age.
According to what has been learned, during this time, the populations of the southwest area, such as that of the Iberian Peninsula, re-colonized the continent when the thaw began about 19,000 years ago and thus they were able to recover areas that had been abandoned to the north of the continent, although this advance was slowed by another migratory wave that arrived from the Middle East, which imposed their genetics.
From that moment on suffered different changes in the European population. Yes, it is highlighted by David Reich, attached to the Harvard Medical School and main author of this research together with Manuel González Morales, of the International Institute for Prehistoric Research of the University of Cantabria.
As Reich stated, “The genetics of some groups gradually expanded throughout the continent, displacing the inhabitants of the Southwest. Today we can see how the DNA of these people persists for many thousands of years until the arrival of agriculture about 8,000 years ago.”.
For his part, Cosimo Posth, a scientist at the Max Planck Institute for the Science of Human History in Jena, stated that don't know where humans went during the coldest period during the Ice Age, something they are currently investigating.
He has also ensured that one of the remains they have analyzed, known as "The Red Lady" by El Mirón (in Cantabria) reveals a genetic link to a branch of sapiens that predates the first colonizers. Now, with advances in the study of DNA and new technologies, it will be possible to learn more about this unknown and it will surely not take long to learn more about this topic.
After studying History at the University and after many previous tests, Red Historia was born, a project that emerged as a means of dissemination where you can find the most important news of archeology, history and humanities, as well as articles of interest, curiosities and much more. In short, a meeting point for everyone where they can share information and continue learning.
