How is the sense of smell different from humans
Answers
Explanation:
The odors compared between species also have to be the same. That sounds obvious, but while humans have sniffed around 3,300 different scents for science — out of the trillions possible — the highest number for animals is 81, by spider monkeys.
Answer:
Humans detect smells by inhaling air that contains odor molecules, which then bind to receptors inside the nose, relaying messages to the brain. Most scents are composed of many odorants; a whiff of chocolate, for example, is made up of hundreds of different odor molecules.
Scents that humans are particularly attuned to include chemical components in bananas, flowers, blood and sometimes pee. In 2013, Laska and colleagues tested the abilities of humans, mice and spider monkeys to detect urine odors found in common mouse predators.
Smell is in fact the strongest human sense, and contrary to popular belief, may be just as powerful as the snout sniffers in dogs and rodents (to certain degrees).
The human nose has roughly 400 types of scent receptors that can detect at least 1 trillion different odours. The human nose can distinguish at least 1 trillion different odours, a resolution orders of magnitude beyond the previous estimate of just 10,000 scents, researchers report today in .
