Lemur Vocalizing (image) Princeton University Share Print E-Mail Caption Princeton University research suggests that idle conversation could be a social-bonding tool passed down from primates. The researchers found that ringtailed lemurs (above) use vocalizations far more selectively than previously thought, primarily exchanging calls with individuals with which they have close relationships. The findings could have implications for how scientists understand the evolution of primate vocalizations and human speech.
