#15 Honeybees can recognize human faces.

For a long time, we believed that only large-brained mammals could distinguish faces. But the humble honeybee shook that theory up!

Bees can distinguish between many different flowers, so it was theorized that they might tell people apart. Scientists discovered that honeybees could recognize a familiar face, even days after being trained to do so.

Fun Fact: Bees see faces in a compilation of 5,000 individual images – kind of like pixels.
