Honeybees Can Recognize Human Faces

Honeybees can distinguish human faces with tiny brains containing only 1 million neurons. Human brains have 86 billion. Researchers showed bees photographs and rewarded them with sugar water for choosing the correct face. Bees learned to recognize faces with 80% accuracy. This ability probably evolved for recognizing flowers. Bees must remember which flowers contain nectar - face recognition uses similar pattern matching. Source: Journal of Experimental Biology
