In all additionally surveyed sectors, we observe what was already indicated by Biblio data, i.e. quite abrupt replacement of HG culture with F culture with few signs of co-existence *.

Established HG tend to gradually disappear after chewers enter the scene and contrary to previous ones (e.g. HG settlements in sector 48), all new HG settlements after the „chewer invasion“ are just one-time shots. Farmer settlements have first difficulties to establish themselves in places formerly inhabited by HG, it is in regions where no prior HG was observed (sector 46) where important bastions of the chewer culture are established.

This does not seem like a sign of peaceful gradual cultural assimilation but rather as a sign of takeover (e.g. invasion).

H0: An HG settlement as old as 7200BP will be excavated on island in sector 35, maybe even older settlements on Frica's northernmost coast (sector 25).
