Baboons feeding at the Mpala Research Centre, Laikipia, Kenya. The benefits that baboons can acquire depend on where they are positioned in their group. Those at the front typically are the first to get access to food, whereas those in the centre may be safer from predators. Tracking the movements of baboons using high-resolution GPS reveals that individuals tend to occupy consistent positions within their troop. These patterns at the group level could arise from differences in the rules individuals use when deciding where to move. See the paper ‘Individual variation in local interaction rules can explain emergent patterns of spatial organization in wild baboons’ by Farine et al, published in Proceedings B (http://dx.doi.org/10.1098/rspb.2016.2243).
