A groundbreaking study published in Nature Heritage has utilized 'sediDNA' (sedimentary ancient DNA) extracted from the North Sea floor to reconstruct the ecosystem of Doggerland. This submerged landmass once connected Britain to mainland Europe. Researchers identified the DNA of dozens of plant and animal species, alongside human genetic markers, providing evidence of a much denser population of Mesolithic hunter-gatherers than previously estimated.
The data suggests that as sea levels rose around 8,000 years ago, the inhabitants of Doggerland did not simply disappear but migrated in a series of planned movements that significantly influenced the genetic makeup of contemporary Northern European populations. This 'climate archaeology' breakthrough offers new insights into how ancient societies adapted to rapid environmental change.
