I don't think their b/B ratio peaks over humans, at least not
on the charts I've seen.

But yes, on the charts they're up there with the chimps and humans.

I can't say :-)..

It depends on how intelligence is defined. It's possible that
whales and dolphins might have intelligence levels of chimps
or so. But it's impossible to test them like humans because
if they have speech we don't understand them. As for
chimp intelligence, we do have indications that they can solve
some problems which even diehards can admit takes intelligence.

I don't have any problems attributing intelligence to
animals. Living things all have intelligence. I'd like to
attribute intellgience even to machines.

The problem is one of finding the right scale and a way
of measuring it, or at least finding some rough scale.

They are not too far behind. I wish there was something like a
thermometer with which we can touch their heads and get readings
but they don't exist.

What I don't like is people constantly telling me what can't
be done. It sounds like I'm breaking the second law of
thermodynamics but it's nothing like it. What can be done
will probably be eventually done. If I don't do it someone
else will. And if you don't do it, someone else will.

I think it's time to give up PC.

Maybe some of its brain is got a sonar remote-sensing program
and that's what makes it have a large brain.

BTW, how do bats measure up on this scale? That might give us
a clue as to how much space sonar takes up.
