These tribes all built fine buildings, canoes, and great art without being dependent on intensive agriculture.
That is correct. They lived in an expecially abundant area.
They were pretty much permanent in their location.
That is very unusual for hunter gatherers, who usually have to move around to follow the game.
Perhaps it should be considered a hybrid of farming and hunter-gathering.
Also, keep in mind that almost a rchaeologists are trained Marxists and it infects their scholarship. You have to be skeptical some of the conclusions but the evidence presented is interesting. Like all information sources these days. I say this as a person with a BA in anthropology.
