Or, as her majesty Faith Hill might say, “This kiss.” And, it turns out, it’s also really old. British scientists say they’ve traced the age of the kiss, to anywhere from 16 million to 21 million years ago, and have found that it was far more common among other species than previously understood.

A new study that examines how kissing evolved suggests that ape ancestors and early humans like Neanderthals probably locked lips with their friends and sexual partners.
