An intriguing confirmation of deep similarities in brain chemistry across the animal kingdom.
Plants are known to go to great lengths to attract pollinators.
They produce all sorts of chemicals that affect animal behavior: sugar in nectar, memorable fragrances, even substances in fruit than can act like laxatives in the service of quick seed dispersal.
Lars Chittka, who studies bee behavior at Queen Mary, University of London, and wrote a commentary on the research in the same issue of Science, said that in the marketplace of plants seeking pollinators, the plants “want their customers to remain faithful,” thus the sugary nectar and distinctive scents.
