Are Marmoset Monkeys Taking Turns To Talk?

When we talk to one another, we take turns. This simple rule seems to apply to all human conversation, whether the speakers are English city-dwellers or Namibian hunter-gatherers.

One person speaks at a time and, barring the occasional interruption, we wait for our partner to finish before grabbing the conch. Timing is everything: cutting someone off is rude; leaving pregnant pauses is awkward. You need to leave a Goldilocks gap—something just right.
