I didn't know that about elephants!
The brain/bodyweight ratio is often quoted when comparing animals, but you
would have a difficult task convincing me that a 4 gram animal with a 2 gram
brain is more intelligent than a human. . Irrespective of body weight, a
smaller brain means less neurons which must surely mean less processing power.
It depends of course which parts of the brain are bigger or smaller in
different species.. Areas of the brain devoted to movement and dexterity, or
to homeostasis, wouldn't effect intelligence. Parts involved in memory such
as the hippocampus probably would.
