I want to know the answer to the following question:
What models imply that changes in diversity are guided by a first-order positive feedback?
All the background I'm provided with is that "On the other hand, changes through the Phanerozoic correlate much better with the hyperbolic model (widely used in population biology, demography and macrosociology, as well as fossil biodiversity) than with exponential and logistic models.". Is that enough to answer the question?
