“The rotation changes the state of our consciousness, it disrupts the reaction and coordination of our body and mind, because of which we feel sick, feel dizzy and can even be accompanied by high spirits, as is the case with children riding a carousel,” said Adriano Lameria..

Scientists decided to conduct a study after the emergence of a viral video in which a gorilla from the Dallas Zoo Zola is circling in the pool.

The researchers studied 40 videos that contained footage of the rope spinning, for a total of 709 turns.. Gorillas, chimpanzees, orangutans and bonobos were spinning. The average rotation session was 5.4 rotations and the average rotation rate was 1.43 rotations per second.

The longest session was 28 spins and the fastest single spin was 5 spins per second.

Scientists have concluded that monkeys rotate fast enough to cause a state that in humans is called a "

“Human ancestors, whether or not they had access to psychotropic drugs, may have had the ability to independently induce altered states of proprioception and awareness through rotation,” the team wrote..

Previously, scientists have found that fish can recognize themselves in the photo. This may be a sign of their self-awareness..
