i think this shows only that social species' behaviours are fine tuned to the environment they have evolved in and drastically changing said environment requires the species to adapt in order to survive.

i feel like there should be a pen size above which such an experiment might run indefinetly. but my gut tells me: no matter the size, it will always eventually crash and burn because mice can't "talk it out"

i think the only possible lesson here is: if you send a generation ship to alpha centauri, you better make sure they all have at least one common language.
