Just heard a radio story about this during the drive to work this morning (KQED) - some story about circadian rhythms and how studies showed that flight attendants had lower scores and smaller brains than airport workers; and how hamsters that were jet lagged had less brain growth than normal hamsters...
Anyway, I've got a follow up question. Say you throw a bunch of primitive humans onto a 36-hour planet for 5-10 thousand years (and thousands of generations). Would that be enough time for them to adjust to the new cycle (and feel weird if they ever come back to Earth's 24 hour day) or would that kind of evolution take longer than that?
