Did you know?

There are only 3 animals on the planet with the same brain structure, similar size and have the ever-important ‘brain-fold’ - Humans, Dolphins and Gorillas.

Elephants are up there, but their brain-fold is not quite aligned to the other 3.

Therefore, I’d speculate that those 3 animals are the most complex and ‘powerful’ insomuch as critical thinking, emotions et al.
