Drifting Around Denmark

Get ready for some SGC DNA.  Lots of questions and answers ahead regarding the relationship of SGC with the CWC and BBC nations.  These are the results of radiocarbon analysis on graves associated with the TRB, SGC, CWC and BBC's.  Will update later in the day, getting back in the saddle.


*afternoon update*

Here's one of the individuals that is likely to reveal the genetic affinities of the mysterious Single Gravers.  You may recognize a few of the authors of this paper, and I think a fair guess is that sometime within the next few weeks we'll have a genetic window to Denmark's past like Britain and Spain.  In those previous cases, the isotope/anthropology precedes the genetic paper by a few weeks or months.  They all have RISE numbers assigned, so they may be searchable if you know where to go.



Abstract

We present results of the largest multidisciplinary human mobility investigation to date of skeletal remains from present-day Denmark encompassing the 3rd and 2nd millennia BC. Through a multi-analytical approach based on 88 individuals from 37 different archaeological localities in which we combine strontium isotope and radiocarbon analyses together with anthropological investigations, we explore whether there are significant changes in human mobility patterns during this period. Overall, our data suggest that mobility of people seems to have been continuous throughout the 3rd and 2nd millennia BC. However, our data also indicate a clear shift in mobility patterns from around 1600 BC onwards, with a larger variation in the geographical origin of the migrants, and potentially including more distant regions. This shift occurred during a transition period at the beginning of the Nordic Bronze Age at a time when society flourished, expanded and experienced an unprecedented economic growth, suggesting that these aspects were closely related.

Update.  Nick, got your email.  Today as a bit busy so I’ll be checking it out in the morning

    Love the multidisciplinary methodology. It should be the norm.

      It is nice when genetics is paired with physical anthropology.

    The genetics might help determine the migratory reach of earlier Bell Beaker people.
    I suspect they will be similar to samples from Southern Sweden (RISE 97, RISE 98, RISE 175 and RISE 210), which I estimate to be ancestrally-related to Central European Bell Beakers, but not significantly derived from them. But we shall see ...

      I believe you are correct in that the extent of Beaker surveying, prospecting and settlement was likely a bit more significant in Southern Sweden than is widely assumed. In some ways these frontier settlements may be more difficult to fully appreciate, but the burial orientation and genetics may broaden this understanding.

      In the public domain, I see mainly two-dimensional general analysis of Bell Beaker group genetics, but feel that multi-dimensional analysis of full genetic profiles for Bell Beaker individuals are more instructive. If you would be interested to see some, let me know and I can send them to you.

      Hopefully, the analysis got to you OK.

    The fact that we have R1b-U106 popping up in late neolithic sites more or less inundates these pretentious claims that L51 didn’t spread with SGC clans. We’re getting warmer I can feel it.

    I have just noticed we already have a good genetic profile for one Danish sample from the early part of that era (RISE 61, date-estimated to around 2,670 BC).

    This sample is interesting, as it is suggestive of fairly recent diverse ancestral contributions from all directions, including what I would estimate to be around a 9% contribution from Iberian Chalcolithic-like populations. This is the only direct sign I have seen so far of Iberian Beaker-like DNA appearing in North Central Europe, and (if the dating is accurate) it is perhaps surprisingly early for this.

    If analysed in detail, further early samples from Denmark could provide some very useful insights.
