Due to a production error, Figure 4 in this article was incorrectly replaced with a new version of Figure 1. The correct versions of both figures are reproduced below.

Figure 1. Map of Central Europe showing the main archaeological groups of the third millennium BC (figure by J. Kolář, based on Gerling et al. 2012; Bilger 2018; Kolář 2018).

Figure 4. Correspondence analysis in geographical space; the factor score of burial sites on the first axis is illustrated in Figure 3 (only burial sites with more than two contexts; natural neighbour method of interpolation; figure by J. Kolář, modified from Kolář 2018: fig. 94).
