In fact, we have plenty of company, and you may be surprised to learn who else is on the list. Thus, the amount of encephalisation is, in turn, considered an important factor in intelligence. In recent years, researchers have found that thought processes in animals aren’t a matter of how closely related they are to humans. The issue is made more complex as humans tend to measure intelligence against their own understanding of it. Like dolphins, they've been seen consoling and helping others, and there's even been a recorded instance of one passing the Mirror Test. See Coryphaenoid.

In my experience, people prefer animals that they can relate to, and at first glance, dolphins definitely seem as far from a human as any living creature could get. If human standards for intelligence are applied to non-human animals, however, dolphins come very close to our own brain aptitude levels, suggests Emory University dolphin expert … Throughout studies, geneticists have found that the human genome and the dolphin genome are basically the same. Big Think. This type of interaction allows humans to find out more about the overall intelligence and behaviors of dolphins. There is more going on though with such interactions than just dolphins learning how to perform tricks for shows. They have also been identified with unique personalities. Brain size.
