Hunter-gatherers took refuge in European 'water world' for millennia

Ancient inhabitants of the RhineMeuse river delta resisted population shifts that transformed most of Europe until they helped to catalyse the expansion of Bell Beaker culture.

A western European water world was a holdout for hunter-gatherers for thousands of years.
Ancient inhabitants of the RhineMeuse river delta wetland, riverine and coastal areas of modern-day Netherlands, Belgium and western Germany maintained high levels of hunter-gatherer genetic ancestry. This genetic signature persisted long after most of Europe was transformed into farming and animal-herding-based communities by successive migrations from the east, starting around 9,000 years ago. The findings come from a study published in Nature on 11 February1.
Its really an island of persistence and resistance to the incorporation of external ancestry, says David Reich, a population geneticist at Harvard Medical School in Boston, Massachusetts, who co-led the study.
Cultural integration
For two decades, ancient-genomics laboratories, including Reichs, have painted Europes population history over the past 10,000 years in broad brushstrokes. This work showed that resident hunter-gatherers were, to varying degrees, replaced by Middle Eastern farmers, who were themselves usurped by pastoralists whose ancestry traced back to the central Eurasian steppe (see 'Hunter-gatherers holdouts').
