100 ANCIENT GENOMES SHOW REPEATED POPULATION TURNOVERS IN NEOLITHIC DENMARK

67 Summary
68 Major migration events in Holocene Eurasia have been characterised genetically at broad
regional scales1–4 69 . However, insights on the population dynamics in the contact zones are
hampered by a lack of ancient genomic data sampled at high spatiotemporal resolution5–7 70 . To
71 address this we analysed shotgun-sequenced genomes from 100 skeletons spanning 7,300
72 years of the Mesolithic, Neolithic and early Bronze Age in Denmark and integrated these
with proxies for diet (δ13C & δ15N isotopes), mobility (87Sr/86 73 Sr isotopes), and vegetation
74 cover (pollen). We observe that Danish Mesolithic individuals of the Maglemose,
75 Kongemose and Ertebølle cultures form a distinct genetic cluster related to other Western
76 European Hunter-Gatherers (HGs). Despite shifts in material culture they displayed genetic
77 homogeneity from ~10,500 cal. BP until 5,900 cal. BP when Neolithic farmers with
78 Anatolian-derived ancestry arrived. Although this process was delayed by more than a
79 millennium relative to Central Europe it was very abrupt and resulted in a population
80 turnover with limited genetic contribution from local HGs. The succeeding Neolithic
81 population, associated with the Funnel Beaker Culture, persisted for just ~1000 years before
82 immigrants with eastern Steppe-derived ancestry arrived. This second and equally rapid
83 population replacement gave rise to the Single Grave Culture with an ancestry profile more
84 similar to present-day Danes. In our multiproxy dataset these major demographic events are
85 manifested as parallel shifts in genotype, phenotype, diet, and land use
