Bourville site (chewers), which seems to be located in the region where both cultures first got into contact sometimes around 7100, is of rather short duration, indicating potentially (hostile) destruction of the settlement

Fast demise of chewer’s Talona colony around 7060 corrobates the hypothesis of hostilities

Some years later – around 7000 - the same holds for oriental (Montnesse) and youresian (Mulid) poppy farms

since arrival of farmers in non-Frican regions, no presence of longer-lasting (>1 carbon dated sample period) skinner settlement is observed

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).

Sector 46: Absence of HG settlements. Presence of multiple long-lasting F settlements.

Sector 48: Presence of surprisingly long-lasting HG settlements including the oldest one replaced around 6870 by F settlements.

Sector 28: HG replaced by F between 6900 and 6650.

Sector 74: Short-term HG settlements replaced between 6800 and 6750 with F culture. The youngest discovered HG settlement dates to 6785

Sector 62: HG settlements replaced by F settlements betwen 7150 and 6950.
