Description:But scientists have come up with an evolutionary explanation which perhaps threatens to kill the passion. As many as 80 million bacteria are transferred during a ten-second kiss, according to Dutch biologists. Sharing those germs means both partners are equipped to ward off the infections they might introduce to each other later on. Humans carry trillions of bacteria in the body, which together make up a 'microbiota' — a complex mix of bugs which play a crucial role in digesting food and warding off infections. They discovered that 'there is a direct relationship between the presence of kissing and the level of stratification within a society, with kissing present most frequently in complex societies.
