Ever since the ancient Greeks were sitting around in their round halls, inventing philosophy, and contouring human limitations, people have been convinced that a human’s sense of smell is inferior to that of most animals. Now, a new study begs to differ, showing concrete proof that the homo sapiens sapiens can smell its way out of a conundrum.
Humans Can Even Compete With Dogs When It Comes to Olfactory Acuity
The scientists behind this research found solid proof to bust the myth saying people have a bad sense of smell. Combining new data with historical facts and sources, John P. McGann managed to prove that Poor Human Olfaction is a 19th Century Myth. This study was published in the Journal Science.
Back in the 19th century, a famous anatomist, Paul Broca discovered that the human olfactory bulb was a lot smaller compared to the rest of the brain. He assumed that the sense of smell is affected by this. The myth was also believed and researched by Charles Darwin who mentioned several times in his work that human olfaction is bad.
New studies showed that the human olfactory bulb is actually bigger than the one of some animals. Humans also have the same number of neurons there. The difference is that we have a more complex brain. This helps us distinguish certain odors better.
Another great thing about human smell is that it influences our behavior. Certain odors can cause us to remember things and to recall emotions. This only happens to human because we have a more complex brain than animals. We are not better than dogs at smelling things. It just depends on the odors we smell.
Sometimes we can sense certain odors from miles away, while other times we can’t even distinguish them when we are close. The researchers that conducted this study mentioned that they are going to continue their study and find out more about the human smell. They also stated that, while the human sense of smell is great, we don’t rely on it like animals do.
