That’s apparently what the paper says. In any case, since the population of Canaan grew during the Late Bronze collapse [citation not needed], and olives could certainly be grown on the slopes of the hills of Samaria during the Late Bronze Age [citation not needed], in the case of Canaan, it seems that it was the end of Egyptian rule over Canaan and the corresponding sudden shift in social structure that led to the Late Bronze collapse and the revival of olive cultivation there. Things were probably different in the cases of Cyprus and the Alawite coast, and, possibly, the cases of Anatolia and Greece. I still hope to see the results from the Sea of Galilee core-they might be interesting.
