Scratching can be a sign of stress in many primates, including humans. Research by Jamie Whitehouse

Credit: © andamanse / Fotolia New research sheds light on how “animal personalities” — inter-individual differences in animal behaviour — can drive the collective behaviour and functioning of animal groups such as schools of fish, including their cohesion, leadership, movement dynamics, and group performance. These research findings from the

In other words, the more things change, the more they are the same. While the individual impacts

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
