They are concerned by sweeping DNA studies that they say make unwarranted, and even dangerous, assumptions about links between biology and culture.

“Pots are pots, not people,” goes a common refrain.

Most archaeologists have since cast aside the view that prehistory was like a game of Risk, in which homogenous cultural groups conquer their way across a map of the world.

But last year, reports started circulating that seemed to challenge this picture of stability.

A study analysing genome-wide data from 170 ancient Europeans, including 100 associated with Bell Beaker-style artefacts, suggested that the people who had built the barrow and buried their dead there had all but vanished by 2000 .

But improvements in sequencing technology in the mid-to-late 2000s set the fields on a collision course.

In 2010, scientists led by Eske Willerslev at the Natural History Museum of Denmark used DNA from a lock of hair from a 4,000-year-old native Greenlander to generate the first complete sequence of an ancient-human genome.

The artefacts offer a view of those visitors and their relationship with the wider world.

Changes in pottery styles there sometimes echoed distant trends in continental Europe, such as the appearance of bell-shaped beakers — a connection that signals the arrival of new ideas and people in Britain.

The technology is no silver bullet, he says, but archaeologists ignore it at their peril.

Some archaeologists, however, worry that the molecular approach has robbed the field of nuance.
