**We are learning just how smart insects can be. As I show in my new book, "The Mind of a Bee of a knowledgeable bee on the vertical honeycomb. The movements make reference to gravity and the direction of the sun; since it's dark in the hive, bees that want to learn from the dancer need to touch its abdomen with their antennae. Sometimes, such dances are displayed at night, when no foraging takes place: The dancer appears to think about locations visited on the previous day, without an obvious need to do so at the time. The observation that bees are most likely sentient beings has important ethical implications. Many species of bees are threatened by pesticides and wide-scale habitat loss, and that this spells trouble because we need these insects to pollinate our crops. But is the utility of bees the only reason they should be protected? I don't think so. Bees have a rich inner world and unique perception, and, like humans, are able to think, enjoy and suffer.
