What was the single-grave culture in prehistoric Denmark?

In prehistoric Denmark, the single-grave culture emerged around 2800 BCE during the Neolithic Period. This culture is characterized by the practice of burying individuals in separate, individual graves, marking a departure from the earlier tradition of constructing large, communal megalithic tombs.1

It remains unclear whether the appearance of this culture represents a shift in local customs or the arrival of a new group of people in the region. In central Europe, a similar group known as the Battle-Ax or Single-Grave culture was distinguished by the use of shaft-hole battle-axes, the domestication of horses, and the production of beaker-shaped pottery.12
