Cognitive abilities evolve by natural selection to help an organism cope with problems encountered in the organism’s typical environment. In acacia ants, coevolution with the acacia tree led workers to forage exclusively on the host plant (“in-nest” foraging), instead of the central-place foraging typical for most social insects. To test whether foraging ecology altered the orientation skills of acacia ants, we developed a novel field disorientation assay to evaluate the ability of foraging… CONTINUE READING
