Worth a moment to recall (particularly as we watch the 2024 YR4 impact odds creep up; not that it is that big) that there are relatively regular events where life has to cope with long sunless periods. A big asteroid impact can blot the sky for years. It is quite amazing to think what evolution has to handle with. The aftereffects after a bad asteroid impact are staggering. No sun for years & the entire earth can get cooked for a few hours from the kinetic energy of the ejecta that gets kicked up. Then everything freezes. So survivors typically do well eating carrion, hibernating and burrowing.
