What is a great house?
Why this place?
Why this time?
IFD tells us that habitat suitability is negative density dependent, so how do we get agglomeration effects?
Positive effects at low density are eventually overwhelmed by competition.
Given circumscription, the productivity of an unequal system will increase relative to alternative arrangements.
Can explore this process by looking for times and places where great houses and pueblos co-occur.
