Michelsberg Comes from the Paris basin, and Funnelbeaker comes from Michelsberg. The Archaeological Paralells between the two are very Striking and the most obvious paralell for TRB is Megalithism, Which is a Western European tradition the LBK and post-LBK did not practice.
Further Parelells are the Type 0-1 / Oxie flint axes, which are associated with the Earliest TRB finds. You can also see Michelsberg colonist sites appearing in Northern germany in what is to Become the Funnelbeaker culture
The Type 0-1 flint axes are found all across Western europe, mainly within core Michelsberg areas and the Paris basin.
The construction of Causeways is also associated with this Cultural spread, the earliest from the paris basin and then spreading with Michelsberg 4400bc and Funnelbeaker.
Megalithic long barrows are also a construction staple of the Funnelbeaker, although they are rarely found within the Michelsberg but appear in Brittain
The expansionist tendencies of the Michelsberg lead them to conquer and settle much of Germany. Slave-raids were a common practice into the fractured territories of the cultures preceeding the LBK.
Michelsberg and Chasseen groups are genetically Distinct from LBK, mainly due to HG admixture from the Cardial period. Chasseen is clearly a cline from Cardial toward WHG, and while Michelsberg mostly represents a cline from LBK toward WHG-
It is not entirely within the Post-LBK cluster which is simply LBK groups with extra HG. instead it sits between Chasseen and Post-LBK, which is exactly what you would expect. Furthermore, the main Haplogroup of Chasseen, Michelsberg, TRB and GAC were I2, contrasted by LBK G2a
You can essentially divide the Megalithic world into East and West, West giving rise to Basques, Iberians, Tartessians, Sardinians (?) and East contributing as a heavy substrate into Corded-ware indo european (Avidic substrate) (Reposting due to typo)
@VVeltkrieger Wonderful post! Very timely.
