A groundbreaking study published in the journal Science suggests that bonobos, our closest living genetic relatives, can convey complex thoughts in a way that mirrors some elements of human language. The research, led by Professor Simon Townsend at the University of Zurich, reveals that bonobos can combine different calls to create new meanings, challenging the long-held assumption that humans are the only species capable of this ability.
Using over 400 hours of audio recordings and meticulous notes on group dynamics, the researchers mapped more than 700 vocal calls, including combinations, and found at least four instances where bonobos combined calls to create new meanings. While the exact meaning behind each call is unclear, the researchers were able to make assumptions based on context.
The study’s findings have significant implications for our understanding of human language evolution. By studying bonobos, who share a common ancestor with humans, researchers can gain insights into how humans developed their ability to use language in the distant past.
Experts praised the study as “convincing” and “novel,” highlighting its potential to shed light on the evolutionary origins of language. The research also raises questions about what triggered the emergence of complex verbal communication in humans.
Bonobos, an endangered species with a population estimated to be less than 20,000, offer a unique opportunity for scientists to study human-like behavior and gain a deeper understanding of ourselves. As one expert noted, “losing them would be like losing a part of our heritage.”
