"Two Bohemian Bell Beaker genomes from Allentoft et al. 2015 - RISE568 and RISE569 - are labeled as early Czech Slavs in the new Mathieson et al. 2017 preprint (see rows 148 and 149 in the spreadsheet here).
Obviously these samples were initially wrongly dated to the Bronze Age and misidentified. They really date to 600-900 CE and 660-770 calCE, respectively. It's an unfortunate mistake, but also an interesting situation, because they've been analyzed in great detail in several papers and on this blog, and no one suspected that anything was wrong.
So the fact that these two Medieval Slavs from East Central Europe passed so convincingly for eastern Bell Beakers is a hint of very strong genetic continuity in the region since the Bronze Age. Indeed, they're very similar to present-day Czechs, western Poles (from Poznan), and eastern Germans, except perhaps with lower excess Western Hunter-Gatherer (WHG) ancestry and higher Yamnaya-related ancestry.
This is where RISE569, the higher coverage of the two genomes, clusters in my Principal Component Analysis (PCA) of West Eurasian populations:
Unfortunately, both are females, so there's no Y-DNA data. But I suspect that if there was, we'd probably know something was wrong, because their Y-chromosome haplogroups may have turned out to be relatively young Slavic-specific subclades of R1a-M548 and/or R1a-Z280."
