        [Stewart, Dwight]  I'm glad someone brought this up.  After a minor
        last fall, I have worked with a neurologist/neuropathologist here in
my recovery.
        I asked him a similar question about brain mass/intelligence.  This
guy is
        a top person in his field in the Southwest & told me that the brain
mass vs.
        body mass gauge of intelligence is an "old paradigm".  And that VERY
        discoveries in neurology for humans AND other species is bringing
        paradigm under close scrutiny.  He talked about the development of
        neural network & how it is probably a better gauge of  intelligence
than simple
        mass ratio.  Now, he wasn't saying there was no validity to the old
        ratio gauge, he was simply stating that the neural network is a
better indicator.
        I see him tomorrow, so I'll bring this up.  

        That estimate of a parrot's intelligence may be true.  My
neurologist made the statement 
        that the neural network model implies we may be underestimating the
        of most animals. :-)  Species jingoism?  

        And it's my understanding that neural networks could be implied in
fossil remains.
