Question for group,
Is intelligence in different species convergent evolution?

Define "intelligence"...

But if all these species are intelligent, it either relies on shared
ancestral (plesiomorphic) neural traits, or it is convergently derived
(autapomorophic). We share a lot of homology with octupuses at the
neural cell structure level, more with dolphins (since they're mammals,
and so are we), and more with chimps (since they;re primates, and so are
we). Brain structure homology likewise is inversely related to
phylogenetic distance.

If chimps had ancestors incapable of symbolic reasoning in the Pan
clade, and evolved their own kind of intelligence, then theirs would be
convergent with ours, but probably based on the same shared ancestral
structures.
