Why do chimpanzees struggle with human pointing if they are so intelligent?

Chimpanzees, despite their high intelligence and average IQ comparable to a 3-4 year old human, struggle with declarative human pointing due to fundamental differences in communication intent. Their pointing is typically imperative, focusing on requesting objects, whereas human-dog interactions leverage cooperative, information-sharing gestures. This distinction highlights a divergence in social cognition, where dogs have evolved to interpret human cues for shared attention, a skill less naturally developed in chimpanzees who do not inherently share a communicative need to direct others' attention to objects in the environment.
