Should that be taken literally? Or do we have to wait for, say, Avar and Hunnic genomes to expect more realistic models? Update 15/03/2018: This is where many of the Medieval German samples cluster in my PCA of modern-day Northern European genetic variation (see here). Obviously, I could only run the individuals with wholly or overwhelmingly North European genomes, and most of these turned out to be the males without any signs of ACD. They look very West Germanic.

First real foray into Migration Period Europe: the Gepid, Roman, Ostrogoth and others
This is going to be our first meaningful look at the all important Migration Period, thanks to the recently published Veeramah et al. 2018 paper and accompanying dataset (see here). The Migration Period is generally regarded to have been the time when present-day Europe first began to take shape, in a rather sudden and violent way, with, you guessed it, a lot of migrations taking place. Here's where most of the ancients from Veeramah et al. 2018 cluster in my Principal Component Analysis (PCA) of ancient West Eurasian genetic variation. Those East Germanics (the Gepid and Ostrogoth) are certainly very eastern, and indeed more exotic than I would've ever expected them to be. But I do love surprises like this. The relevant datasheet is available here. Global25 datasheets with many of the same ancients. You can use these datasheets to plot them on 2D or 3D "genetic maps", and model their ancestry proportions. Feel free to share your findings in the comments below. nMonte3 and based mainly on Iron Age (IA) reference samples. I used the same data file for all of the models; it includes scaled coordinates and is available for download here.
