No one trait is sufficient to insure fitness. Every functioning gene in
the vast human genome has contributed to fitness in one way or another.
But I do think that the innate ability to learn is a very important factor
in vertibrate fitness.
I think you have been postulating that intelligence is not selected for,
and that the evidence for this is the fact that human intelligence hasn't
changed in the last few thousand years. I think you could argue that very
little has changed evolutionarily in ANY animal in that time frame. So
this is hardly evidence for or against intelligence being influential in

Wait, so you are just _assuming_ that dolphins probably do things that
seem stupid to you? Isn't that sort of circular logic? What would the
dolphin do? something stupid. how do you know its stupid? Because I
thought it would do that stupid thing.

but you said that dolphins weren't intellegent because they didn't tell
the rest of the pod about the fishing nets. what if they just can't
communicate, or they don't have the necessary vocabulary to describe the
problem? They may be smart, but not have language...

| That a kitten seems to know to use a litter box does not imply intelligence.
I think the fact that you (or the kittens mother) can teach the kitten to
use a litter box certainly does imply intelligence.
