> there wasn't a complete elimination of the HG groups
replyThe annihilated culture was not worried about its haplogroups, it was worried about is survival; its dead now; its haplogroups survive so everything is fine, yes?
It did survive! And it paints a fascinating picture of adaptation. The Yamnaya cultural package brought elite domination and patrilineal succession. So for the I1 line (mesolithic European HG) to not just survive but spread widely across Scandinavia and crowd out the Yamnaya R1 haplogroup suggests that at least one member of the Hunter Gatherers became dominant over the Yamnaya and beat them at the new Bronze Age game they brought to the region.
replywonderful; the culture is dead but one of its remnants at some point had a position of leadership over its conquerors; this is success
replyHowever, the Corded Ware culture that largely displaced EEF in Europe itself had a large EEF component in addition to Yamnaya (and in some places like Sardinia EEF still dominates).
replyBTW, the only modern Indo-European ethnicities/language families that are not Corded Ware-derived are Greek, Albanian, and Armenian. (Indic and Iranic speakers resulted from a Corded Ware migration out of Central Europe back into the steppe, completing the circle begun with the Yamnaya migration out of the steppe into Europe.)
replyThe article is very much making up conclusions not present in the work cited. There were no "wipe outs" or "total turnovers".
replyProbably some sort of jingoist advocating ethnic cleansing writing articles like this.
You're right that "wipeouts" and "total population turnover" basically doesn't exist in our genetic history, but there's one critical exception to that rule of thumb: massive epidemics really do wipe out entire local populations, and given that early farming was involved (with its higher pathogen burden) this cannot be ignored as a factor here.
replyWe can’t say for certain what the causes were, but there are some very striking near-total population replacements we can infer from DNA analysis, such as the disappearance of Neolithic ancestry in Britain over the span of just a century or two.
replyPhys.org is good for DOI links to the studies they butcher and nothing else. It makes me cringe every time I see people discussing their writing seriously, but my God they’re a popular domain.
replyThey’re often sensational and frequently inaccurate or misleading, but often the research they cite is worthwhile.
