In 2011, Marcus Perlman saw a YouTube video of a gorilla named Zola spinning in a circle while playing in a puddle at the Calgary Zoo in Alberta. In 2017, he noticed Zora again. This time it was a viral video from the Dallas Zoo in Texas. Zola swirled in a plastic blue kiddie pool as water splashed around him.
Perlman, a lecturer in English and linguistics at the University of Birmingham, UK, has done research on communicative gestures, and saw a YouTube video that piqued his curiosity about this form of behavior in apes. He searched for more YouTube videos of him spinning apes and found about 400. “They do pirouettes with their feet. They do backflips. They roll sideways. They do somersaults. They roll down hills and they spin on ropes,” Perlman says.
Perlman wasn’t the only one to stick around. Adriano Lameira, a primatologist and evolutionary psychologist at the nearby University of Warwick in England, was also fascinated by Perlman and saw a video of the ape spinning online.Together they co-authored a recent paper Primates It focuses on primate rotation, especially rope rotation. Videos they analyzed showed orangutans, gorillas, chimpanzees, and bonobos holding hands on ropes and vines and turning through the air at dizzying speeds.
At first glance, such rotations may seem like a stereotype. It was more than just a pastime, it was a rich and creative activity for the apes. The animals seemed preoccupied with their movements. They let go of the rope, capsized from the wobble, stood up and spun over and over again.
Kat Hobiter, a primatologist at the University of St Andrews in Scotland, who wasn’t involved in the study, says she’s encountered spinning movements many times while studying chimpanzees and gorillas in the wild. “She’s one of the favorite games of gorillas when they’re young,” she says, noting that in the wild they’re seen more often in gorillas than in other primates. “They literally spin themselves until they collapse and collapse in dizziness, which was uncommon in wild chimpanzees,” Hobiter adds.
In their paper, Lameira and Perlman recorded the rotation and its speed, and speculated about the implications that our closest animal relatives seem to prefer to rotate in the same way that humans do. Many great apes in captivity are retired from medical research, making the hundreds of videos that exist an invaluable resource. “YouTube has given us a ton of data that we could never have collected before,” he says Lameira.
Spinning turns the world into a moving blur for apes, including humans. The emotions it produces disrupt the vestibular system, which senses changes in body movement, orientation, position, and speed. You may feel dizzy, light-headed, light-headed, high-spirited, or giggle. Perhaps for this reason, spinning has become a staple of children’s play. Human children go crazy for playground spinners his bowls and merry-go-rounds, carousels and carnival rides spinning in the air. For people with autism, spinning acts as self-stimulation. In some denominations of Sufism, a branch of Islam, the spiral cult rotates in a circular motion as a form of religious dance, the movement of which induces a spiritual, trance-like state. Lameira and Perlman wrote in their study that “spinning is positively ecstatic.”
The researchers compared the spinning speed of an ape’s rope to that of a human pirouette in professional ballet, the spinning of a Ukrainian hopak dancer, a Sufi whirling cult, and the spinning of a suspended rope by a circus artist. The ape rotated at an average rotational speed of 1.43 revolutions per second, and the maximum speed reached was 3.3 revolutions per second. These are the speeds that induce a physiological “high” in humans.
Humans seek out altered mental states to lose themselves, says Marc Wittmann, a psychologist at the Frontiers Institute for Psychology and Mental Health in Germany and author of the book. Altered States of Consciousness: Experience Beyond Time and Self“In altered states, we lose our sense of self and time and therefore become present-oriented,” he says. “We feel much better when we are focused on the present, without reflecting on the past or the future.”
But Perlman says there’s a giant leap from the sense that humans are spinning to the prediction that gorillas are experiencing altered states of consciousness. Even though they share physiology with primates, gorillas may experience similar physical effects.
“I’ve seen mountain gorillas in the wild spinning wildly, so I’m pretty sure these gorillas are experiencing some sort of sensory impairment,” Hoveter says. they fall to the ground. They fall just like we do,” he says. “Even if you’re back on solid ground, I’m sure the world revolves around them.”
Beyond that basic interpretation, it’s hard to interpret what’s going on in a gorilla’s head.
What happens to apes if gorillas’ consciousness is altered? does not mean that people experience the same kind of mental state changes.” The question of what spin looks like needs to be explored in dogs, horses and birds before scientists can reach any conclusions, she says. We can examine the question of whether spinning is more common in gorillas, and explore other details such as spinning preferences by gender and age.
The origin of spinning and how it developed is another question of intriguing researchers. “You can imagine this being elaborated over thousands of years of human evolution,” Perlman says. “A basic urge for altered perception and altered mental states may be common to our primates.” Many primates eat fermented foods and may be slightly intoxicated. Researchers report that there is
Rotating and consuming fermented fruit raises the bigger issue of how animals entertain themselves and what animal entertainment tells us about their experience being a gorilla or chimpanzee.

Chimpanzees are seen playing with objects.But if we pay more attention what Because they actually do when they’re immersed in play, Byrne writes, it could reveal more about their cognition. Lameira hopes this could be one way to test whether our evolutionary ancestors regulated mood by deviating from normal arousal just for the thrill.
Seeing apes spinning increases the likelihood that non-human primates indulge in the same pleasures that manipulate normal sensory experience in the same way that humans alter their consciousness through drugs, alcohol, or physical activity. “It accentuates the subjectivity of the experience,” Perlman says.
