Resent investigations have proved that any single anthropological type might hardly be attributed to the Corded Ware substratum (see: Kristiansen 1989, P.216; Ebbesen 1997: 86).
Studies by Schwidetzky (1978, 1980) and Menk (1980) have shown that the Corded Ware complex is biologically heterogeneous implying the substratum culture.

Construction of regional matrixes of finds, related to the presumable A-Horizon should be regarded as one of the most important aspects of actual consideration of the problem.
Since the phenomenon of the so-called A-Horizon has been discovered from the typological studies of the artefacts, it would be reasonable to start from the consideration of this aspect of the problem.
In study of the Corded Ware artefacts two following aspects are generally emphasized: 1) Typological dissimilarity between regional branches of the CWC (Malmer 1962: 678, 805; Malmer 1975: 115); 2) Typological continuity within local Neolithic cultural complexes and traditions (Behrens 1997: 21; Becker 1990; see also: ┼berg 1912).
The solution of the problem should be in the methodological field.
In most cases the critics of the A-horizon concept appeal to the antiquated conceptions of the A-Horizon, based on the presumption of pure cultural transmission over vast territories. Rose, we should not expect to be able to trace population movements in terms of single cultural complexes (Rose 19).
It is reasonable to note that the typological method should be used with a great caution in regard of issues of cultural transition and succession, since from the typological investigations are known such cases, when, for instance, patterns of decoration and form of particular kind of artefacts (vessels) were far richer than can be captured by a simple set of types, and when form and decoration of beakers did not correspond to a set of types at all even within a certain restricted territory (Boast 1998: 400).
Comparative case study of tentative material categories as cultural markers has shown that ceramic manufacture (non-decorative steps) has highest rates of significance together with food way preferences and domestic architecture layout and spatial organization (Clark 2001).
Aivar Kriiska considered all of the four known Corded Ware Culture dates from The present state of working out of the problem requires further application of newly developed calibration curves to the obtained datings, and bringing them into system in accordance with the chronological sequence.
