"The origin of the kiss is the removal of ticks and teeth from the fur."

In ancient times, kissing was considered both an expression of affection and an act of greeting. It was also an expression of reconciliation, forgiveness, and respect.
There is a lot of disagreement about the origin of the kiss.
In the meantime, some scientists argue that Keith's technique did not start with romantic gestures, but with practical reasons for removing ticks and teeth
According to foreign media such as Daily Star, researchers at the University of Warwick in the United Kingdom said the kissing method dates back to the ancient ancestor of the great apes about 7 million years ago.
Great apes groom each other with their lips and remove itchy animals from their fur as they come down from trees.
The researchers explained that there are many types of kisses, but they all have something in common that there is a 'lip sticking out and a little inhalation'.
The researchers also gave the example of chimpanzees, which use their fingers to brush pests and use their mouths at the end to nibble on remaining teeth and ticks.
He then argued that it has evolved into a form of expressing love to humans.
The findings were recently published in the journal 『Evolutionary Anthropology』.
Meanwhile, a 10-second kiss can carry 80 million bacteria and 700 other strains.
According to a study published in the journal Microbiome, we observed the kissing behavior of 21 couples and found that couples who kiss at least nine times a day shared similar oral bacteria.
The oral bacteria were normal, and kissing could help improve immune system and intestinal health, the researchers explained.
Adrian Benjamin, a nutritionist at ProVen Probiotics, said "The exchange of bacteria during the kiss can introduce beneficial microorganisms into the oral microbiome, which can be converted into the digestive system and the intestinal microbiome"
