Whether we Philematologists, the scientists who study kissing, aren't exactly sure why humans started locking lips in the first place. The most. 14 Jul A new study finds that half of human cultures don't practice romantic lip-on-lip kissing. Animals don't tend to bother either. So how did it evolve?. 25 Nov What's more romantic than two people hugging, looking into each other's eyes, and then, to put the final touches on the idyllic moment, kissing each other on the lips? At that instant, the kiss transports the lovers to another plane of existence – high above the mundane. Only when romance ends does the.
Pecking, smooching, French kissingand playing tonsil-hockey — there are as many names for kissing as there are ways to do it. Whether we use it as an informal greeting or an intensely romantic gesture, kissing is one of those ingrained human behaviors that seems to defy explanation.
The key chemical is a pheromone called androstenone that triggers the females' desire to mate. Francesca throws herself between the two brothers. Next, slide the inside of your forearm across the same edge of the same teeth as if you were biting your arm.
So why is it that we love to pucker up? Kissing is more than just showing affection. Philematologists, the scientists who study kissingaren't exactly sure why humans started locking lips in the first place.
The most likely theory is that it stems from primate mothers passing along chewed food to their toothless babies. The lip-to-lip contact may have been passed on through evolution, not only as a necessary means of survival, but also as a general way to promote social bonding and as an expression of love.
The tragic ending comes when the jealous Gianciotto, rapier in hand, is about to kill Paolo. Having a different MHC means less immune overlap and a better chance of healthy, robust offspring. When the berries are all plucked the privilege ceases.
The kissing we associate with romantic courtship may help us to choose a good mate, send chemical signals, and foster long-term relationships. Part of this information exchange is most likely facilitated by pheromones, chemical signals that are passed between animals to help send messages. We know that animals use pheromones to alert their peers of things like mating, food sources, and danger, and researchers hypothesize that pheromones can play a role in human behavior as well.
Although the vomeronasal organs, which are responsible for pheromone detection and brain function in animals, are thought to be vestigial and inactive in humans, research indicates we do communicate with chemicals. The first study to indicate that chemical signals play a role in attraction was conducted by Claud Wedekindover a decade ago. Women sniffed the worn t-shirts of men and indicated which shirts smelled best to them. They preferred the scent of man whose major histo-compatibility complex MHC — a series of genes involved in our immune system — was different from their own.
Having a different MHC means less immune overlap and a better chance of healthy, robust offspring. Kissing may be a subtle way for women to assess the immune compatibility of a mate, before she invests too much time and energy in him. Perhaps a bad first kiss means more than first date jitters — it could also mean a real lack of chemistry. Behavioral research supports this biological reasoning. Inresearchers at University of Albany studied 1, college students and found significant differences in how males and females perceived kissing.
Although common in courtship, females put more importance on kissingand most would never have sex without kissing first. Since females across species are often the choosier ones when it comes to mate selection, these differences in kissing behavior make sense. Men are also more likely to initiate French kissing and researchers hypothesize that this is because saliva contains testosterone, which can increase libido.

But kissing isn't all mating practicality ; it also feels good. Researcher Wendy Hill and colleagues at Lafayette College looked at how oxytocin, which is involved in pair bonding and attachment, and cortisol, Why Do People Kiss On The Lips stress hormone, changed after people kissed.
Using a small sample of college couples that were in long-term relationships, they found cortisol levels decreased after kissing. The longer the couples had been in a relationship, the further their levels dropped. Cortisol levels also decreased for the control group—couples that just held hands—indicating that social please click for source, in general, can decrease stress levels Looking at oxytocin levels, the researchers found that they increased only in the males, whereas the researchers thought it would increase in both sexes.
At an Association for the Advancement of Science meeting on the science of kissing, Helen Fischeran evolutionary biologist, posits multiple reasons for lip locking. She believes that kissing is involved in the three main types of attraction humans have: Kissing, she postulates, evolved to help on all three fronts. Saliva, swapped during romantic kisses, has testosterone in it; feel-good chemicals are distributed when we kiss that help fuel romance ; and kissing also helps unleash chemicals that promote bonding, which provides for long-term attachment, necessary for raising offspring.
Yet, not all cultures or mammals kiss. Some mammals have close contact with each others' faces via licking, grooming, and sniffing, which may transmit the necessary information. And although chimps may pass food from mother to child, the notoriously promiscuous bonobos are apparently the only primates that truly kiss. So it seems that as much as we use kissing to gather genetic and compatibility information, our penchant for kissing also has to do with our cultural beliefs surrounding it.
Whether we live in a place where kissing is reserved for close acquaintances, or somewhere where a casual greeting means a one, two, or three cheeker, one thing does remain highly consistent: A study published in Nature found that twice as many adults turn their heads to the right rather than continue reading left when kissing.
This behavioral asymmetry is thought to stem from the same preference for head turning during the final weeks of gestation and during infancy.
