“Ew,” my friends would tell me when I’d try to describe it.
Simply by using their sense of smell, mice end up choosing mates with MHC types that are not too similar, yet not too different, from their own, as a way to avoid inbreeding and to make their offspring evolutionarily as strong as possible.
Whether or not these odors play the same behavior-influencing role in human mate choice, however, is still up for some debate.
It’s also a highly social sense, linked to memory, emotions and interactions with other people—encouraging us to draw closer or stay away.
The nose also deserves credit for much of our pleasure, especially when it comes to another of our chemical senses: taste.
These pheromones shape the social and sexual lives of some creatures, like invertebrates, insects and rodents, by attracting them towards evolutionarily compatible partners, which are desirable because they lead to better offspring.
In these animals, genes in the major histocompatibility complex (MHC)—part of the immune system—produce unique odors; when another animal gets a whiff, they’re either attracted or repelled based on immune compatibility.Smell Dating is the first mail-order smell dating service, but its creators aren’t the only ones wagering that we’re better at choosing partners through our noses than our eyes.By sniffing other people’s body odor instead of swiping right on their photos, the thinking goes, we rely on primal bodily intuition.“Isolating the odor part to it has been very, very difficult.” Animal studies are able to control for the diet, genes, upbringing and diseases that alter body odor, but that’s impossible to do in humans.Scientists can also expose lab animals to bodily secretions that would be far too unseemly to use in human studies.“So much of we think of as taste is really smell,” says Richard Doty, director of the Smell and Taste Center at the University of Pennsylvania Medical Center.Tags: Adult Dating, affair dating, sex dating
