I think making a causal connection is a real stretch. The world was getting warmer, growing seasons were longer, glaciers were retreating. Sounds as though it was a good time to start agriculture.
There can be no exact timing on events that far in the past.
Ignore dendrochronology. They have a continuous calendar going back that far. When they finally pull up a post from a building down in the oxygen-free depths of the Black Sea they will be able to date it to the year the tree was cut.
