Ok, first off, Hiflier, I must say I enjoy and appreciate your input and ideas, at times out the box thinking, and willingness to explore and consider various pathways of inquiry and interpretation . Kudos.
However, some of the things you stated five posts up are quite rather "sapiens-centric" and somewhat display the high handed self-impressed assumptions and conclusions our species is so well known for ("I know! they always do that! like they're some 'chosen monkey' or something! like who died(or they drove to extinction) and made them the pinnacle of evolution? they don't even have fur!")
Body configuration does not dictate intelligence as long as there are biologic processes that support firstly, self awareness(so like most every organism that interacts with an environment) and secondly awareness of the external reality. With these two, intelligence may expand and cognition progress.
"Brain development is not open ended whereby a raccoon say, can figure out a complex math problem"
Any more advanced species observing us could well say the same thing....
"these things are so limited, they haven't the capacity to progress past rudimentary string theory or quantum mechanics! it's a dead end..."
We as humans have virtually no means to perceive, much less determine, the levels of abstraction within the communications and minds of other living organisms. To dismiss even the possibility of such is an act of arrogance that blinds us to potentials we've yet to conceive or realize.
. "There is no doubt that it is animal and its brain will limit it to animal even though it's body type will allow it to do so much more than any other animal. Its diminished right brain capacity will insure that it never rises above that level"
once again, this could just as easily apply to our species, all a matter of perspective and self-image.
Even within the paradigm of body type determining limits of cognitive development, the anatomic similarity would indicate strong parallels of potentials between BF's and humans. So, consider the idea that our physically founded drive progressing us through our biologic then cognitive/social development resulted in our departure from strictly physiological guidance as our cognitive capacity allowed us to visualize then manifest new pathways to manage corporeal existence, as seen in our technology, realization and application of abstract conceptualization, social constructs, and the delivery of pizza. So, in light of the form parallels, this physically founded drive element must(for the sake of the discussion)exist within the BF in some perhaps slightly altered, but none the less potent, presence and level, which could have focused and directed their attention and intent, manifesting in development of awareness, abstraction, and environmental utilization, which while disparate from our own in content, is equal in extent.
Just a thought......
