More mass migrations with no evidence of population DNA changing due to wars between the homo sapiens being invaded by foriegn relations.
It is suggested that 100% of the Iberian peninsula males were replaced within 400 years - a total replacement of the male population of Andorra, Spain, Portugal and Gibraltar in the Bronze Age.
In Britain during this pre historic period it has been stated that over 90% of the population were replaced by all conquering yet no warring evidence Beaker civilisation. Rapid DNA changes?
A migration from Central Europe transformed the genetic make-up of people in Spain during the Bronze Age, a study reveals.
DNA evidence shows the migrants streamed over the Pyrenees, replacing existing male lineages across the region within a space of 400 years.
An even more extreme pattern of replacement occurred at much the same time in Britain, where Beakers replaced 90% of the overall ancestry that was there before they arrived.
Stone Age crisis
Mass movements of peoples and civilizations due to rapid localised climate changes, perhaps triggered through electromagnetic universe events? Plasma mythology catastrophes.
It remains unclear whether violence played a role or whether a male-centric social structure was more important.
One of the triggers may have been a crisis that caused population numbers to plunge in Europe towards the end of the Neolithic period (which preceded the Bronze Age).
Co-author Iñigo Olalde, from Harvard Medical School, US, said: "It would be a mistake to jump to the conclusion that Iberian men were killed or forcibly displaced." He added: "The archaeological record gives no clear evidence of a burst of violence in this period."
Ancient migration transformed Spain's DNA
Perhaps the Beaker bowls and other pottery such as in Israel with the chevrons/triangles/diagonals representing what was or is seen in the skies? These sort of patterns on pots are seen all over Europe including Malta and also in other continents around the world.
We reveal sporadic contacts between Iberia and North Africa by ~2500 BCE and, by ~2000 BCE, the replacement of 40% of Iberia’s ancestry and nearly 100% of its Y-chromosomes by people with Steppe ancestry.
We show that, in the Iron Age, Steppe ancestry had spread not only into Indo-European–speaking regions but also into non-Indo-European–speaking ones, and we reveal that present-day Basques are best described as a typical Iron Age population without the admixture events that later affected the rest of Iberia.
The genomic history of the Iberian Peninsula over the past 8000 years
Another option is that electromagnetic activity changes the EMF of the planet and local magnetic fields and could rapidly evolve our ancestors DNA.
