If the dating estimates in the article are right, I think this might even have been caused by the prior Preclassic Collapse a few centuries before that. Remember, the dates given are a full two millenia before colonialism and a lot can happen to cause societies to change and history and knowledge to be lost over that timescale; our historical knowledge of much of Europe during this time period isn't exactly great either.
