Human sense of smell is as good as other mammals: Study

Human sense of smell is much more powerful than it is usually given credit for, and it also plays a larger role in maintaining health and behavior than previously thought, according to a new study.

A team led by John McGann, a neuroscientist at Rutgers University-New Brunswick in New Jersey, found in the new review that humans’ sense of smell is just as good as that of other mammals.

Sharing their findings, McGann said, “People often think of dogs and rats as the superior sniffers in the animal kingdom, but humans also have an extremely keen sense of smell. The fact is the sense of smell is just as good in humans as in other mammals, like rodents and dogs.”

The researchers found that humans have the ability to discriminate among 1 trillion different odors. A number of previous studies suggested that humans can detect only around 10,000 different smells.

The interesting finding of the new study appeared in the most recent edition of the widely-acclaimed journal Science.
