Crows and chimpanzees are thought to have last had a common ancestor 300 million years ago. Bees are thought to have had a common ancestor with them 600 million years ago. But crows, chimpanzees, and bees are all much more closely related to life forms that have not attracted attention for their intelligence. Are we just missing their intelligence? Or perhaps the question of unusual intelligence in some birds and other life forms but not others is one of the fruitful mysteries of science that invites further study.
