Lateralization in the Invertebrate Brain : Left-right asymmetry of olfaction in bumble bee, Bombus terrestris
Brain and behavioural lateralization at the population level has been recently hypothesized to have evolved under social selective pressures as a strategy to optimize coordination among asymmetrical individuals. Evidence for this hypothesis have been collected in Hymenoptera: eusocial honey bees showed olfactory lateralization at the population level, whereas solitary mason bees only showed indivi
