Not so fast. Sight isnt the only feature nocturnal animals rely on. When scientists from the University of Chicago asked a group of women to sniff T-shirts worn for two consecutive nights by different men, the women pinpointed their closest genetic matches even though there could be millions of unique combinations of MHC genotypes.

Adding to the intrigue is the fact that the number of neurons found in those olfactory bulbs is remarkably consistent across mammals, McGann reports. This suggests foxes have evolved a complex language of chemical communication. Previous studies have shown that African Elephants can distinguish between odor molecules with extremely tiny structural variations. Owl eyes, for example, are so big that they cant move in the socket, but their wide pupils help them collect more light.
