Agriculture spread to Europe thousand of years ago from the South to the distant North, with successive steps, according to the Swedish-danish scientific research. The study analysed the DNA of the four [inhabitants of Scandinavia] of the Neolithic period and found that they had many more genes in common with today’s Southern Europeans, as the Greeks, Cypriots the inhabitants of Sardinia, than with any other European people.
The researchers of the Universities of Upsala, Stockholm, and Copenhagen, having at their head and
This discovery by the Scandinavian scientists shows that the ancient farmers transported their agricultural knowledge and technique from the South to the rest of Europe, up to the frozen North, where they finally mingled with the indigenous populations, while teaching them how to grow their food rather than hunt and gather fruits.
The farming way of life originated in the Near East some 11,000 years ago and had reached most of the European continent 5000 years later. However, the impact of the agricultural revolution on demography and patterns of genomic variation in Europe remains unknown. We obtained 249 million base pairs of genomic DNA from ~5000-year-old remains of three hunter-gatherers and one farmer excavated in Scandinavia and find that the farmer is genetically most similar to extant southern Europeans, contrasting sharply to the hunter-gatherers, whose distinct genetic signature is most similar to that of extant northern Europeans. Our results suggest that migration from southern Europe catalyzed the spread of agriculture and that admixture in the wake of this expansion eventually shaped the genomic landscape of modern-day Europe.
