I reckon....
its depends on the smells that they used.

I can believe that a hieghtened sense of smell may have evolved when we where hunting mammoth and digging for grubs. So if the test smells were "mammoth scent" and "grub smell" - fair enuf. However, if they were , and as I suspect, "McDonalds Death Burger" and "Fried Chicken Coronary" then no, I would be a little suspicious of these findings.
