Thank you for this article which is showing us that the intelligence is not the way we thought so far. And it also proves that we are not as intelligent as we might think over other living beings. Most of the time we, as the humans make a categorization on the animals by using our intelligence testing methods like IQ tests. Thus we think that we are the most intelligent ones on the planet and the monkeys are the second, octopuses are the third..etc. However it is very weird to make such reasoning like this. In our daily lives we clearly see that other animals can find out really considerable solutions to survive.
