Face Time: Bees can tell apart human portraits

Honeybees will learn to zoom up to particular human faces in a version of a facial-recognition test used for people, researchers say.

The new evidence suggests that face recognition doesn't require a big brain, he and his colleagues propose in the Dec. 15 Journal of Experimental Biology.
