Baboons live in and travel in stable groups of up to 150 individuals, ranging from 30 kilo adult males to infants. New research shows that all baboons compromise their preferred speed in order to keep the group together, but the smallest members are forced to adjust the most, thereby footing the greatest energy bill.
