It is difficult to judge and rank the intelligence of animals with a unified standard, because different animals have different intelligence performance in different aspects. The following are some animal intelligence rankings for certain specific aspects:
1. Mammals with high intelligence: humans, chimpanzees, dolphins, elephants, dogs, etc.
2. Birds with high intelligence: crows, parrots, passenger pigeons, etc.
3. Reptiles with high intelligence: chameleons, lizards, monitor lizards, etc.
4. Invertebrates with high intelligence: octopuses, bees, ants, etc.
It should be noted that these rankings are based only on certain specific aspects of performance, and their IQ cannot be simply compared with that of humans. At the same time, scientists also believe that the intelligence of many animals is far beyond our cognition and understanding, and there is still much room for further research and exploration.
