The science of kissing

Recently, I came across a rather unusual sight: A couple engaging in a lip-lock in broad daylight right by the escalator in Garuda Mall, Bangalore. My mother, who was with me, turned away and said, “Chee, chee, what is the world coming to?”
I gently reminded her that the world as we know it would be finished if humans didn’t kiss. Not to put too Darwinian a point on it, Mom, I said, but kissing is a superbly effective way to select a mate and pass on your genes. It is essential for the survival of the species.
Osculation: That’s the scientific name for kissing, and an average person spends two weeks of his or her life practising the artYou need to eat more fibre, my mother said in the completely tangential way that mothers are wont to talk. Eat your vegetables, take an oil bath, polish your shoes. What, I ask you, does that have to do with kissing? Or anything else for that matter? But as Bertie Wooster says, aunts will be aunts, and mothers will be mothers.
Growing up, I never saw my parents kiss. As a nation, we Indians don’t emphasize kissing—not in our movies (until very recently), not as the culmination of marriage vows (“you may kiss the bride”, which I personally think ought to be rewritten to “you may kiss your spouse”), and certainly not in public as an affirmation of our love and lust for each other.
According to a great article about kissing in the Scientific American, Finns don’t kiss very much either. They get into a sauna nude with a whole community of people but as a nation, Finland doesn’t buy into osculation, which is the scientific— and rather inept term—for kissing. Neither do certain tribes in Polynesia, Madagascar and Tierra del Fuego. Some Mongolian tribes breathe down on their child’s head in lieu of a kiss.
All of which led me to question the whole notion of a lip-lock. After all, you don’t need kissing for the survival of the species. Not technically anyway. People use other parts of their anatomy for that. A kiss is delicious and pleasurable, yes, but what purpose does it serve in the evolutionary sense?
Freud believed that kissing was just an offshoot of the suckling reflex. We suckle as babies; we kiss as adults, proving once again that we never grow up. Anthropologists feel that, as with many things, we learned from the primates before us. Chimps, for instance, mouth feed their young. It took a few aeons and several species to figure out that the mouth could be used for more pleasurable activities than passing on food particles.
Birds still do this, but we humans have invented cutlery for the whole feeding thing. We use our lips to masticate, yes, but also to osculate. Ergo, the 21st century version where Harry and Sally, or Sunehri and Aryan, pucker up.
Other studies have also advanced the view that kissing helps in the selection of a mate. When you kiss someone, your orbicularis orbis muscle contracts, allowing you to pucker. Meanwhile, blood rushes to your lips, your body gets warm, your neural synapses fire away and levels of the cortisol ‘stress’ hormone drop.
