Study finds maternal obesity in mice increases microRNA levels
in the hypothalamus in offspring, leading to overeating

   Somehow I doubt it's all *that* simple ...
   In times of plenty, many species increase not only
   their reproductive rates but also size (including
   fatness) to unconsciously "take advantage of the
   situation". This continues until famine arrives, then
   the big offspring are at a disadvantage. This sort
   of picture perhaps describes the emergence of
   megafauna, and their decline.
