  We study the evolution of black hole entropy and temperature in collapse
scenarios, finding three generic lessons. First, entropy evolution is
extensive. Second, at large times, entropy and temperature ring with twice the
frequency of the lowest quasinormal mode. Third, the entropy oscillations
saturate black hole area theorems in general relativity. The first two features
are characteristic of entanglement dynamics in `democratic' models. Solely
based on general relativity and Bekenstein-Hawking entropy formula, our results
point to democratic models as microscopic theories of black holes. The third
feature can be taken as a prediction for democratic models coming from black
hole physics.
