Additionally, I wouldn't wonder about this "Northern component" being split up in the future, with more data available, because the Neolithic expansion happened to a large part from inside of the older spectrum, yet there was a differentiation present if comparing f.e. the Eastbaltic area with that of Southern Russia and the Ukraine.
I guess there might be something to find here too, further distinguishing the "real North Eastern Mesolithic" from those elements which were related, but expanded from the South in the Neolithic and Metal Age eras.
If this is recognisable in the archaeological record, why not in the genes? So far most of the time, if the archaeological record and typological analysis showed something clearly, the better the genetic tests were, the more they showed of this...
