Interesting, and thanks for clarification.

One thing this article gets right is the necessity of concentration of people into agricultural-conducive areas for the magic of domestication to reveal itself. Even if it happened earlier than the Younger Dryas, or around its onset, which your 14K date would indicate, there had to be a long time for its replication and spread, which I’ve always thought the YD forced.

The now-submerged settlements probably had fields and corrals and whatnot, but it's not likely any evidence thereto has survived. Same goes for Watson Brake.
