Honeybees' waggle dance no longer useful in some cultivated landscapes
For bees and other social insects, being able to exchange information is vital for the success of their colony. One way honeybees do this is through their waggle dance, which is a unique pattern of behavior, which probably evolved more than 20 million years ago.
