While the Funnel(-neck-)beaker culture (short TRB or TBK from (German) Trichter(-rand-)becherkultur, ca 4300 – 2800 BC), an archaeological culture in north-central Europe, isn’t exactly the LBK, the TRB origins have to be sought rather in the central European LBK than in the Mediterranean Cardium pottery. According to a craniometrical cluster analysis by Ilse Schwidetzky, the Swedish neolithic is very similar to the central European middle neolithic Rössen culture, and both are close to LBK.

The main difference between the Danubian cultures and the Cardium derived cultures is that the latter seem more strongly dominated by haplogroup G, which in turn seems to imply a stronger presence of the (Southern part of the) Caucasus component, while the former may have had more haplogoup I and Haplogroup R1b3.
