Princeton University researchers discovered that marmosets (a kind of new world monkey) take turns speaking with one another, similar to people! During their vocal exchanges, which can last up to 30 minutes, the monkeys wait their turn to speak. They don’t interrupt each other.

According to one of the study’s authors, Asif Ghazanfar:

“We were surprised by how reliably the marmoset monkeys exchanged their vocalizations in a cooperative manner, particularly since in most cases they were doing so with individuals that they were not pair-bonded with.

“This makes what we found much more similar to human conversations and very different from the coordinated calling of animals such as birds, frogs, or crickets, which is linked to mating or territorial defense.”

This research on marmoset vocalizations could provide clues about the early development of conversation in humans.
