(That's more than twice the number of olfactory genes in domestic dogs and five times more than in humans.
The following animals were tested in the battle of the schnozes:-
  1. Elephant - 1948
  2. Rat - 1207
  3. Cow - 1196
  4. Mouse - 1130
  5. Horse - 1066
  6. Dog - 811
  7. Guinea Pig - 796
  8. Rabbit - 768

  10. Chimpanzee - 380
  11. Marmoset - 366
  12. Macaque - 309
