A brand new research is shedding gentle on the violent historical past of Scandinavia which noticed a number of waves of mass homicide throughout Denmark in only a thousand years.
A group of worldwide researchers analyzed DNA samples from roughly 100 human stays present in southern Scandinavia by a course of referred to as shotgun sequencing. These stays span roughly 7,300 years, from the Mesolithic interval, when hunter-gatherer life had been warning, to the Neolithic interval, when people started settling and farming was ascendant, to the Early Bronze Age.
The research, revealed within the journal Nature, discovered that reasonably than co-existing peacefully, the hunter-gatherers in what’s now Denmark, had been wiped out by farmer-settlers.
“This transition has previously been presented as peaceful,” stated Lund University paleoecologist Anne Birgitte Nielsen. “However, our study indicates the opposite. In addition to violent death, it is likely that new pathogens from livestock finished off many gatherers.”

The area on which the researchers targeted their research has a local weather appropriate for foraging and farming and preserved human stays, enabling deep analysis of gene flows between populations in addition to adjustments in vegetation.

The research discovered that round 5,900 years in the past, farmers started settling the realm and killed off hunters, foragers, and fishers within the course of.
It was beforehand thought that the 2 populations combined, as previous analysis indicated the first Scandinavians shared round 30% of their genomes from hunter-gatherers. But the most recent analysis means that the hunter-gatherers’ DNA was nearly completely erased.
These early farmers – referred to as the “Funnelbeaker culture,” and have zero genetic relation to modern-day Danes – lived for round 1,000 years earlier than one other wave of settlers moved in from the realm of southern Russia. This new group, changed the Funnelbeakers, giving rise to a brand new group referred to as the “Single Grave Culture” and has an ancestry profile that’s extra much like present-day Danes.

The researchers hope that such insights into historic DNA can clarify modern-day well being patterns equivalent to why a number of sclerosis is extra pronounced amongst white, northern Europeans than these within the south.
