Not sure why you are being downvoted. Seems like lot of people with high ego are not ready to accept the truth that a human has way less knowledge than a world encyclopedia with infinite and practically perfect memory.
Otherwise researching intelligence in animals would be a completely futile pursuit since they have no way of "knowing" facts communicated in human language.
Well, thank you for editing your own comment and adding that last bit, because it really is the crux of the issue and the reason why OP is being downvoted.
Having all of the worlds knowledge is not the same as being smart.
The smartest kid in class was not the one that memorized the most facts.
