Human and Ape Laughter Traced to Common Ancestor 15 Million Years Ago

Comparative Study of Laughter in Humans and Apes

According to НВ — Техно: On June 29 at 11:00, Science Alert published findings from a study that analyzed tickling-induced laughter recordings from 13 apes alongside those of four young children. The research revealed that both human and great ape laughter share a similar rhythm, with consistent intervals between individual sounds-pointing to a shared evolutionary origin dating back roughly 15 million years.

Lead author Chiara De Gregorio, a primatologist at the University of Warwick, stated:

“Humans and other great apes have been laughing in comparable ways for about 15 million years.”

The study examined archival recordings of captive apes being tickled during earlier experiments, as well as new recordings of children laughing during play at home. According to Brittany Florkiewicz, an animal communication specialist at Lyon College who was not involved in the study, different species developed their laughter patterns based on the unique demands of their social lives.

Why This Research Matters

Scientists have long investigated the origins of laughter, but most efforts have focused on animal facial expressions rather than vocal patterns. Human laughter has evolved to become faster and more complex over time, with its sound shifting depending on the context. The researchers urge further examination of vocalizations in other animals-including dogs, horses, and cats-to deepen our understanding of how communication evolved across species.

This study highlights the importance of exploring the evolutionary ties between humans and their closest animal relatives. Comparing laughter offers fresh insights into the development of social interactions in both humans and apes, while opening up new avenues for future research in zoology and communication science. Recognizing shared features in vocal communication may also help improve methods for interacting with animals in captivity.

This study not only sheds light on the evolutionary roots of laughter but also emphasizes the broader implications of animal communication. Understanding how different species convey emotions can deepen our insight into social behaviors.
