Humor in Our Primate Relatives: An Insight into Playful Behavior
Written on
Chapter 1: The Jestful Nature of Primates
Recent studies have unveiled that certain human-like primates exhibit distinct forms of humor. Observations reveal that younger members of these species often engage in playful teasing towards their older counterparts. Researchers propose that this "monkeying around" might provide insights into the evolution of humor in humans.

Humor has long been recognized for its beneficial effects on human health, such as reducing stress and anxiety. The act of laughing triggers the release of endorphins, known as the "happiness hormones," which promote feelings of well-being and can even diminish pain.
Section 1.1: The Role of Humor in Social Bonds
Joking and playful banter serve to strengthen social connections. Psychologists refer to this as a "universal language" among humans. Sharing humor can foster new friendships and reinforce existing ones.
“Humor involves intricate cognitive skills: grasping social norms, understanding others' perspectives, and predicting their responses,” state the authors of a study published in the journal "Proceedings of the Royal Society B." Interestingly, some human-like primates display strikingly similar behaviors. Young primates, particularly those aged 3 to 5 years, often tease their elders, a phenomenon that has intrigued scientists.
Subsection 1.1.1: Observational Insights
Researchers meticulously analyzed 75 hours of footage from zoos in San Diego and Leipzig, documenting 142 clear instances of teasing among primates. “We devised a method for identifying playful behaviors and applied it to the videos of human-like primates in captivity. All four species exhibited persistent playful behaviors, often characterized by playful attributes,” the researchers from the University of California noted.
Section 1.2: Understanding Teasing Behavior
The findings suggest that teasing serves various purposes, including capturing attention. Young primates often engage in playful teasing during relaxed moments, differentiating it from other forms of play. The observed teasing behaviors are unpredictable, often incorporating surprise elements and provocation.

Chapter 2: The Evolutionary Roots of Humor
The authors propose that the origins of humor may be traced back to our evolutionary ancestors. “From an evolutionary perspective, the presence of playful teasing across the four great ape species, akin to the teasing observed in human infants, suggests that humor and its cognitive foundations may have been present in our last common ancestor, dating back at least 13 million years,” the researchers explained.
This video titled "Humans Are Apes (& Here's Why)" features anthropologist Zachary Cofran discussing our evolutionary connections with primates, enhancing our understanding of humor's development.
In total, the researchers identified 18 distinct teasing behaviors, such as unexpected nudges or gentle hits. Most of these actions are intended to provoke specific reactions or to attract the attention of the targeted individual.
In another insightful video, "95% of your behavior is primate behavior," Frans de Waal explores the links between human behavior and our closest primate relatives, further emphasizing the evolutionary significance of humor.
Section 2.1: Implications for Future Research
The scholars hope their study will encourage further exploration of humor and jokes in other species, aiming to deepen our understanding of this multifaceted behavior. They also aspire to raise awareness about the profound connections we share with our closest relatives.
