Smells also help some animals find mates. However, for modern humans, the olfactory system is much less important that it was for human ancestors and distant relatives. Scientists were skeptical that they could confirm a correlation. Researchers designed a series of experiments to test participants' spatial memory and sense of smell. In one test, participants explored a virtual city, trekking down each street and passing by the city's 20 landmarks. Afterwards, participants were q...
