The Beaker folk have been known to archeology for a long time, 60 years that I know of, and probably longer. They are known in Britain by the drinking mugs, beakers, in their graves. These are handsome handleless, pottery mugs, good for 12-14 ounces of beer (modern measure), quite distinctive. They used to think that the beaker folk were traders, who came to Britain, trading bronze to neolithic natives who were still using flint.
The DNA people got to work recently analyzing beaker folk DNA and have declared that all modern Britons are descended from the beaker folk. The earlier neolithic people who had raised Stonehenge were wiped out by the beaker invaders. This raises the beaker folk from mere bronze traders to ancestors of all of Britain. The U-Tube videos putting forth this quite new interpretation are non technical and do not give any of the observations supporting this heady conclusion, but I have not seen any postings of contrary conclusions so they probably have it right.
