In my previous analysis all "steppe" samples located very close modern Europeans. Making it simple let's follow Bronze Age Scandinavians (baSca). They seem to be the westernmost group of all Bronze Age samples.
After adding South Asians all "steppe" samples move eastwards and Bronze Age Scandinavians with them to the same direction. Regarding "steppe" samples this starts to look like Jones et al. Sorry about flipping pictures, SmartPca does it sometimes.
After adding East Asians changes happen again, "steppe" samples move back to west and some of Bronze Age Scandinavians are now among Basques (this is interesting indeed, think about western megaliths, but let's forget it now).
As a conclusion I would say that it is not always relevant to make up one's mind about clines between modern and ancient samples if we are not aware of the history between ancient and modern samples. We can select modern samples coincidentally or even in a prejudiced manner and perhaps lose meaningful history.
