The average IQ of a chimpanzee is estimated to be around 20 to 25 when compared to human IQ scales. However, it’s important to note that IQ tests are designed for humans and may not accurately measure the intelligence of chimpanzees. Chimpanzees exhibit complex behaviors such as problem-solving, tool use, and social interactions, which indicate a high level of cognitive ability. While their intelligence is different from that of humans, they are considered one of the most intelligent non-human animals.
