Overview

• Researchers discovered that marmosets use 'phee-calls' to address specific individuals, similar to human names.
• This vocal labeling ability was previously observed only in humans, dolphins, and elephants.
• Marmoset families share similar vocal labels, indicating a form of dialect and learned behavior.
• The study suggests that these communication skills may have evolved to maintain social cohesion in dense rainforest habitats.
• Insights from this research could enhance understanding of the evolution of human language and social communication.
